+ WebDriver: auto-install pytest instead of importing it from wpt tools directory
+ https://bugs.webkit.org/show_bug.cgi?id=180243
+
+ Reviewed by Brian Burg.
+
+ We don't really need the (old) version included in wpt tools dir, so we can simply remove it and use autoinstall
+ instead.
+
+ * Scripts/webkitpy/thirdparty/__init__.py:
+ (AutoinstallImportHook.find_module): Check pytest.
+ (AutoinstallImportHook._install_pytest): Install pytest.
+ * Scripts/webkitpy/webdriver_tests/webdriver_selenium_executor.py: Import autoinstalled pytest.
+ * Scripts/webkitpy/webdriver_tests/webdriver_test_runner_w3c.py:
+ (WebDriverTestRunnerW3C.run): Update the subtest path since the new pytest uses a different strategy for
+ rootdir.

-**Bug Fixes**
-
-* Improve error message when a plugin fails to load.
- Thanks `@nicoddemus`_ for the PR.
-
-* Fix (`#1178 <https://github.com/pytest-dev/pytest/issues/1178>`_):
- ``pytest.fail`` with non-ascii characters raises an internal pytest error.
- Thanks `@nicoddemus`_ for the PR.
-
-* Fix (`#469`_): junit parses report.nodeid incorrectly, when params IDs
- contain ``::``. Thanks `@tomviner`_ for the PR (`#1431`_).
-
-* Fix (`#578 <https://github.com/pytest-dev/pytest/issues/578>`_): SyntaxErrors
- containing non-ascii lines at the point of failure generated an internal
- py.test error.
- Thanks `@asottile`_ for the report and `@nicoddemus`_ for the PR.
-
-* Fix (`#1437`_): When passing in a bytestring regex pattern to parameterize
- attempt to decode it as utf-8 ignoring errors.
-
-* Fix (`#649`_): parametrized test nodes cannot be specified to run on the command line.

-2.9.0
-=====
-
-**New Features**
-
-* New ``pytest.mark.skip`` mark, which unconditionally skips marked tests.
- Thanks `@MichaelAquilina`_ for the complete PR (`#1040`_).
-
-* ``--doctest-glob`` may now be passed multiple times in the command-line.
- Thanks `@jab`_ and `@nicoddemus`_ for the PR.
-
-* New ``-rp`` and ``-rP`` reporting options give the summary and full output
- of passing tests, respectively. Thanks to `@codewarrior0`_ for the PR.
-
-* ``pytest.mark.xfail`` now has a ``strict`` option, which makes ``XPASS``
- tests to fail the test suite (defaulting to ``False``). There's also a
- ``xfail_strict`` ini option that can be used to configure it project-wise.
- Thanks `@rabbbit`_ for the request and `@nicoddemus`_ for the PR (`#1355`_).
-
-* ``Parser.addini`` now supports options of type ``bool``.
- Thanks `@nicoddemus`_ for the PR.
-
-* New ``ALLOW_BYTES`` doctest option. This strips ``b`` prefixes from byte strings
- in doctest output (similar to ``ALLOW_UNICODE``).
- Thanks `@jaraco`_ for the request and `@nicoddemus`_ for the PR (`#1287`_).
-
-* Give a hint on ``KeyboardInterrupt`` to use the ``--fulltrace`` option to show the errors.
- Fixes `#1366`_.
- Thanks to `@hpk42`_ for the report and `@RonnyPfannschmidt`_ for the PR.
-
-* Catch ``IndexError`` exceptions when getting exception source location.
- Fixes a pytest internal error for dynamically generated code (fixtures and tests)
- where source lines are fake by intention.
-
-**Changes**
-
-* **Important**: `py.code <http://pylib.readthedocs.org/en/latest/code.html>`_ has been
- merged into the ``pytest`` repository as ``pytest._code``. This decision
- was made because ``py.code`` had very few uses outside ``pytest`` and the
- fact that it was in a different repository made it difficult to fix bugs on
- its code in a timely manner. The team hopes with this to be able to better
- refactor out and improve that code.
- This change shouldn't affect users, but it is useful to let users aware
- if they encounter any strange behavior.
-
- Keep in mind that the code for ``pytest._code`` is **private** and
- **experimental**, so you definitely should not import it explicitly!
-
- Please note that the original ``py.code`` is still available in
- `pylib <http://pylib.readthedocs.org>`_.
-
-* ``pytest_enter_pdb`` now optionally receives the pytest config object.
- Thanks `@nicoddemus`_ for the PR.
-
-* Removed code and documentation for Python 2.5 or lower versions,
- including removal of the obsolete ``_pytest.assertion.oldinterpret`` module.
- Thanks `@nicoddemus`_ for the PR (`#1226`_).
-
-* Comparisons now always show up in full when ``CI`` or ``BUILD_NUMBER`` is
- found in the environment, even when ``-vv`` isn't used.
- Thanks `@The-Compiler`_ for the PR.
-
-* ``--lf`` and ``--ff`` now support long names: ``--last-failed`` and
- ``--failed-first`` respectively.
- Thanks `@MichaelAquilina`_ for the PR.
-
-* Added expected exceptions to ``pytest.raises`` fail message.
-
-* Collection only displays progress ("collecting X items") when in a terminal.
- This avoids cluttering the output when using ``--color=yes`` to obtain
- colors in CI integrations systems (`#1397`_).
-
-**Bug Fixes**
-
-* The ``-s`` and ``-c`` options should now work under ``xdist``;
- ``Config.fromdictargs`` now represents its input much more faithfully.
- Thanks to `@bukzor`_ for the complete PR (`#680`_).
-
-* Fix (`#1290`_): support Python 3.5's ``@`` operator in assertion rewriting.
- Thanks `@Shinkenjoe`_ for report with test case and `@tomviner`_ for the PR.
-
-* Fix formatting utf-8 explanation messages (`#1379`_).
- Thanks `@biern`_ for the PR.
-
-* Fix `traceback style docs`_ to describe all of the available options
- (auto/long/short/line/native/no), with `auto` being the default since v2.6.
- Thanks `@hackebrot`_ for the PR.
-
-* Fix (`#1422`_): junit record_xml_property doesn't allow multiple records
- with same name.

-- fix #1034: Add missing nodeid on pytest_logwarning call in
- addhook. Thanks Simon Gomizelj for the PR.
-
-- 'deprecated_call' is now only satisfied with a DeprecationWarning or
- PendingDeprecationWarning. Before 2.8.0, it accepted any warning, and 2.8.0
- made it accept only DeprecationWarning (but not PendingDeprecationWarning).
- Thanks Alex Gaynor for the issue and Eric Hunsberger for the PR.
-
-- fix issue #1073: avoid calling __getattr__ on potential plugin objects.
- This fixes an incompatibility with pytest-django. Thanks Andreas Pelme,
- Bruno Oliveira and Ronny Pfannschmidt for contributing and Holger Krekel
- for the fix.
-
-- Fix issue #704: handle versionconflict during plugin loading more
- gracefully. Thanks Bruno Oliveira for the PR.
-
-- Fix issue #1064: ""--junitxml" regression when used with the
- "pytest-xdist" plugin, with test reports being assigned to the wrong tests.
- Thanks Daniel Grunwald for the report and Bruno Oliveira for the PR.
-
-- (experimental) adapt more SEMVER style versioning and change meaning of
- master branch in git repo: "master" branch now keeps the bugfixes, changes
- aimed for micro releases. "features" branch will only be be released
- with minor or major pytest releases.
-
-- Fix issue #766 by removing documentation references to distutils.
- Thanks Russel Winder.
-
-- Fix issue #1030: now byte-strings are escaped to produce item node ids
- to make them always serializable.
- Thanks Andy Freeland for the report and Bruno Oliveira for the PR.
-
-- Python 2: if unicode parametrized values are convertible to ascii, their
- ascii representation is used for the node id.
-
-- Fix issue #411: Add __eq__ method to assertion comparison example.
- Thanks Ben Webb.
-- Fix issue #653: deprecated_call can be used as context manager.
-
-- fix issue 877: properly handle assertion explanations with non-ascii repr
- Thanks Mathieu Agopian for the report and Ronny Pfannschmidt for the PR.
-
-- fix issue 1029: transform errors when writing cache values into pytest-warnings
-
-2.8.0
-=====
-
-- new ``--lf`` and ``-ff`` options to run only the last failing tests or
- "failing tests first" from the last run. This functionality is provided
- through porting the formerly external pytest-cache plugin into pytest core.
- BACKWARD INCOMPAT: if you used pytest-cache's functionality to persist
- data between test runs be aware that we don't serialize sets anymore.
- Thanks Ronny Pfannschmidt for most of the merging work.
-
-- "-r" option now accepts "a" to include all possible reports, similar
- to passing "fEsxXw" explicitly (isse960).
- Thanks Abhijeet Kasurde for the PR.
-
-- avoid python3.5 deprecation warnings by introducing version
- specific inspection helpers, thanks Michael Droettboom.
-
-- fix issue562: @nose.tools.istest now fully respected.
-
-- fix issue934: when string comparison fails and a diff is too large to display
- without passing -vv, still show a few lines of the diff.
- Thanks Florian Bruhin for the report and Bruno Oliveira for the PR.
-
-- fix issue736: Fix a bug where fixture params would be discarded when combined
- with parametrization markers.
- Thanks to Markus Unterwaditzer for the PR.
-
-- fix issue710: introduce ALLOW_UNICODE doctest option: when enabled, the
- ``u`` prefix is stripped from unicode strings in expected doctest output. This
- allows doctests which use unicode to run in Python 2 and 3 unchanged.
- Thanks Jason R. Coombs for the report and Bruno Oliveira for the PR.
-
-- parametrize now also generates meaningful test IDs for enum, regex and class
- objects (as opposed to class instances).
- Thanks to Florian Bruhin for the PR.
-
-- Add 'warns' to assert that warnings are thrown (like 'raises').
- Thanks to Eric Hunsberger for the PR.
-
-- Fix issue683: Do not apply an already applied mark. Thanks ojake for the PR.
-
-- Deal with capturing failures better so fewer exceptions get lost to
- /dev/null. Thanks David Szotten for the PR.
-
-- fix issue730: deprecate and warn about the --genscript option.
- Thanks Ronny Pfannschmidt for the report and Christian Pommranz for the PR.
-
-- fix issue751: multiple parametrize with ids bug if it parametrizes class with
- two or more test methods. Thanks Sergey Chipiga for reporting and Jan
- Bednarik for PR.
-
-- fix issue82: avoid loading conftest files from setup.cfg/pytest.ini/tox.ini
- files and upwards by default (--confcutdir can still be set to override this).
- Thanks Bruno Oliveira for the PR.
-
-- fix issue768: docstrings found in python modules were not setting up session
- fixtures. Thanks Jason R. Coombs for reporting and Bruno Oliveira for the PR.
-
-- added ``tmpdir_factory``, a session-scoped fixture that can be used to create
- directories under the base temporary directory. Previously this object was
- installed as a ``_tmpdirhandler`` attribute of the ``config`` object, but now it
- is part of the official API and using ``config._tmpdirhandler`` is
- deprecated.
- Thanks Bruno Oliveira for the PR.
-
-- fix issue808: pytest's internal assertion rewrite hook now implements the
- optional PEP302 get_data API so tests can access data files next to them.
- Thanks xmo-odoo for request and example and Bruno Oliveira for
- the PR.
-
-- rootdir and inifile are now displayed during usage errors to help
- users diagnose problems such as unexpected ini files which add
- unknown options being picked up by pytest. Thanks to Pavel Savchenko for
- bringing the problem to attention in #821 and Bruno Oliveira for the PR.
-
-- Summary bar now is colored yellow for warning
- situations such as: all tests either were skipped or xpass/xfailed,
- or no tests were run at all (this is a partial fix for issue500).
-
-- fix issue812: pytest now exits with status code 5 in situations where no
- tests were run at all, such as the directory given in the command line does
- not contain any tests or as result of a command line option filters
- all out all tests (-k for example).
- Thanks Eric Siegerman (issue812) and Bruno Oliveira for the PR.
-
-- Summary bar now is colored yellow for warning
- situations such as: all tests either were skipped or xpass/xfailed,
- or no tests were run at all (related to issue500).
- Thanks Eric Siegerman.
-
-- New ``testpaths`` ini option: list of directories to search for tests
- when executing pytest from the root directory. This can be used
- to speed up test collection when a project has well specified directories
- for tests, being usually more practical than configuring norecursedirs for
- all directories that do not contain tests.
- Thanks to Adrian for idea (#694) and Bruno Oliveira for the PR.
-
-- fix issue713: JUnit XML reports for doctest failures.
- Thanks Punyashloka Biswal.
-
-- fix issue970: internal pytest warnings now appear as "pytest-warnings" in
- the terminal instead of "warnings", so it is clear for users that those
- warnings are from pytest and not from the builtin "warnings" module.
- Thanks Bruno Oliveira.
-
-- Include setup and teardown in junitxml test durations.
- Thanks Janne Vanhala.
-
-- fix issue735: assertion failures on debug versions of Python 3.4+
-
-- new option ``--import-mode`` to allow to change test module importing
- behaviour to append to sys.path instead of prepending. This better allows
- to run test modules against installated versions of a package even if the
- package under test has the same import root. In this example::
-
- testing/__init__.py
- testing/test_pkg_under_test.py
- pkg_under_test/
-
- the tests will run against the installed version
- of pkg_under_test when ``--import-mode=append`` is used whereas
- by default they would always pick up the local version. Thanks Holger Krekel.
-
-- pytester: add method ``TmpTestdir.delete_loaded_modules()``, and call it
- from ``inline_run()`` to allow temporary modules to be reloaded.
- Thanks Eduardo Schettino.
-
-- internally refactor pluginmanager API and code so that there
- is a clear distinction between a pytest-agnostic rather simple
- pluginmanager and the PytestPluginManager which adds a lot of
- behaviour, among it handling of the local conftest files.
- In terms of documented methods this is a backward compatible
- change but it might still break 3rd party plugins which relied on
- details like especially the pluginmanager.add_shutdown() API.
- Thanks Holger Krekel.
-
-- pluginmanagement: introduce ``pytest.hookimpl`` and
- ``pytest.hookspec`` decorators for setting impl/spec
- specific parameters. This substitutes the previous
- now deprecated use of ``pytest.mark`` which is meant to
- contain markers for test functions only.
-
-- write/refine docs for "writing plugins" which now have their
- own page and are separate from the "using/installing plugins`` page.
-
-- fix issue732: properly unregister plugins from any hook calling
- sites allowing to have temporary plugins during test execution.
-
-- deprecate and warn about ``__multicall__`` argument in hook
- implementations. Use the ``hookwrapper`` mechanism instead already
- introduced with pytest-2.7.
-
-- speed up pytest's own test suite considerably by using inprocess
- tests by default (testrun can be modified with --runpytest=subprocess
- to create subprocesses in many places instead). The main
- APIs to run pytest in a test is "runpytest()" or "runpytest_subprocess"
- and "runpytest_inprocess" if you need a particular way of running
- the test. In all cases you get back a RunResult but the inprocess
- one will also have a "reprec" attribute with the recorded events/reports.
-
-- fix monkeypatch.setattr("x.y", raising=False) to actually not raise
- if "y" is not a pre-existing attribute. Thanks Florian Bruhin.
-
-- fix issue741: make running output from testdir.run copy/pasteable
- Thanks Bruno Oliveira.
-
-- add a new ``--noconftest`` argument which ignores all ``conftest.py`` files.
-
-- add ``file`` and ``line`` attributes to JUnit-XML output.
-
-- fix issue890: changed extension of all documentation files from ``txt`` to
- ``rst``. Thanks to Abhijeet for the PR.
-
-- fix issue714: add ability to apply indirect=True parameter on particular argnames.
- Thanks Elizaveta239.
-
-- fix issue890: changed extension of all documentation files from ``txt`` to
- ``rst``. Thanks to Abhijeet for the PR.
-
-- fix issue957: "# doctest: SKIP" option will now register doctests as SKIPPED
- rather than PASSED.
- Thanks Thomas Grainger for the report and Bruno Oliveira for the PR.
-
-- issue951: add new record_xml_property fixture, that supports logging
- additional information on xml output. Thanks David Diaz for the PR.
-
-- issue949: paths after normal options (for example ``-s``, ``-v``, etc) are now
- properly used to discover ``rootdir`` and ``ini`` files.
- Thanks Peter Lauri for the report and Bruno Oliveira for the PR.
-
-2.7.3 (compared to 2.7.2)
-=============================
-
-- Allow 'dev', 'rc', or other non-integer version strings in ``importorskip``.
- Thanks to Eric Hunsberger for the PR.
-
-- fix issue856: consider --color parameter in all outputs (for example
- --fixtures). Thanks Barney Gale for the report and Bruno Oliveira for the PR.
-
-- fix issue855: passing str objects as ``plugins`` argument to pytest.main
- is now interpreted as a module name to be imported and registered as a
- plugin, instead of silently having no effect.
- Thanks xmo-odoo for the report and Bruno Oliveira for the PR.
-
-- fix issue744: fix for ast.Call changes in Python 3.5+. Thanks
- Guido van Rossum, Matthias Bussonnier, Stefan Zimmermann and
- Thomas Kluyver.
-
-- fix issue842: applying markers in classes no longer propagate this markers
- to superclasses which also have markers.
- Thanks xmo-odoo for the report and Bruno Oliveira for the PR.
-
-- preserve warning functions after call to pytest.deprecated_call. Thanks
- Pieter Mulder for PR.
-
-- fix issue854: autouse yield_fixtures defined as class members of
- unittest.TestCase subclasses now work as expected.
- Thannks xmo-odoo for the report and Bruno Oliveira for the PR.
-
-- fix issue833: --fixtures now shows all fixtures of collected test files, instead of just the
- fixtures declared on the first one.
- Thanks Florian Bruhin for reporting and Bruno Oliveira for the PR.
-
-- fix issue863: skipped tests now report the correct reason when a skip/xfail
- condition is met when using multiple markers.
- Thanks Raphael Pierzina for reporting and Bruno Oliveira for the PR.
-
-- optimized tmpdir fixture initialization, which should make test sessions
- faster (specially when using pytest-xdist). The only visible effect
- is that now pytest uses a subdirectory in the $TEMP directory for all
- directories created by this fixture (defaults to $TEMP/pytest-$USER).
- Thanks Bruno Oliveira for the PR.
-
-2.7.2 (compared to 2.7.1)
-=============================
-
-- fix issue767: pytest.raises value attribute does not contain the exception
- instance on Python 2.6. Thanks Eric Siegerman for providing the test

- Thanks Floris Bruynooghe for reporting and Bruno Oliveira for the PR.
-
-- fix issue748: unittest.SkipTest reports to internal pytest unittest plugin.
- Thanks Thomas De Schampheleire for reporting and Bruno Oliveira for the PR.
-
-- fix issue718: failed to create representation of sets containing unsortable
- elements in python 2. Thanks Edison Gustavo Muenz.
-
-- fix issue756, fix issue752 (and similar issues): depend on py-1.4.29
- which has a refined algorithm for traceback generation.
-
-
-2.7.1 (compared to 2.7.0)
-=============================
-
-- fix issue731: do not get confused by the braces which may be present
- and unbalanced in an object's repr while collapsing False
- explanations. Thanks Carl Meyer for the report and test case.
-
-- fix issue553: properly handling inspect.getsourcelines failures in
- FixtureLookupError which would lead to to an internal error,
- obfuscating the original problem. Thanks talljosh for initial
- diagnose/patch and Bruno Oliveira for final patch.
-
-- fix issue660: properly report scope-mismatch-access errors
- independently from ordering of fixture arguments. Also
- avoid the pytest internal traceback which does not provide
- information to the user. Thanks Holger Krekel.
-
-- streamlined and documented release process. Also all versions
- (in setup.py and documentation generation) are now read
- from _pytest/__init__.py. Thanks Holger Krekel.
-
-- fixed docs to remove the notion that yield-fixtures are experimental.
- They are here to stay :) Thanks Bruno Oliveira.
-
-- Support building wheels by using environment markers for the
- requirements. Thanks Ionel Maries Cristian.
-
-- fixed regression to 2.6.4 which surfaced e.g. in lost stdout capture printing
- when tests raised SystemExit. Thanks Holger Krekel.
-
-- reintroduced _pytest fixture of the pytester plugin which is used
- at least by pytest-xdist.
-
-2.7.0 (compared to 2.6.4)
-=============================
-
-- fix issue435: make reload() work when assert rewriting is active.
- Thanks Daniel Hahler.
-
-- fix issue616: conftest.py files and their contained fixutres are now
- properly considered for visibility, independently from the exact
- current working directory and test arguments that are used.
- Many thanks to Eric Siegerman and his PR235 which contains
- systematic tests for conftest visibility and now passes.
- This change also introduces the concept of a ``rootdir`` which
- is printed as a new pytest header and documented in the pytest
- customize web page.
-
-- change reporting of "diverted" tests, i.e. tests that are collected
- in one file but actually come from another (e.g. when tests in a test class
- come from a base class in a different file). We now show the nodeid
- and indicate via a postfix the other file.
-
-- add ability to set command line options by environment variable PYTEST_ADDOPTS.
-
-- added documentation on the new pytest-dev teams on bitbucket and
- github. See https://pytest.org/latest/contributing.html .
- Thanks to Anatoly for pushing and initial work on this.
-
-- fix issue650: new option ``--docttest-ignore-import-errors`` which
- will turn import errors in doctests into skips. Thanks Charles Cloud
- for the complete PR.
-
-- fix issue655: work around different ways that cause python2/3
- to leak sys.exc_info into fixtures/tests causing failures in 3rd party code
-
-- fix issue615: assertion re-writing did not correctly escape % signs
- when formatting boolean operations, which tripped over mixing
- booleans with modulo operators. Thanks to Tom Viner for the report,
- triaging and fix.
-
-- implement issue351: add ability to specify parametrize ids as a callable
- to generate custom test ids. Thanks Brianna Laugher for the idea and
- implementation.
-
-- introduce and document new hookwrapper mechanism useful for plugins
- which want to wrap the execution of certain hooks for their purposes.
- This supersedes the undocumented ``__multicall__`` protocol which
- pytest itself and some external plugins use. Note that pytest-2.8
- is scheduled to drop supporting the old ``__multicall__``
- and only support the hookwrapper protocol.
-
-- majorly speed up invocation of plugin hooks
-
-- use hookwrapper mechanism in builtin pytest plugins.
-
-- add a doctest ini option for doctest flags, thanks Holger Peters.
-
-- add note to docs that if you want to mark a parameter and the
- parameter is a callable, you also need to pass in a reason to disambiguate
- it from the "decorator" case. Thanks Tom Viner.
-
-- "python_classes" and "python_functions" options now support glob-patterns
- for test discovery, as discussed in issue600. Thanks Ldiary Translations.
-
-- allow to override parametrized fixtures with non-parametrized ones and vice versa (bubenkoff).
-
-- fix issue463: raise specific error for 'parameterize' misspelling (pfctdayelise).
-
-- On failure, the ``sys.last_value``, ``sys.last_type`` and
- ``sys.last_traceback`` are set, so that a user can inspect the error
- via postmortem debugging (almarklein).
-
-2.6.4
-=====
-
-- Improve assertion failure reporting on iterables, by using ndiff and
- pprint.
-
-- removed outdated japanese docs from source tree.
-
-- docs for "pytest_addhooks" hook. Thanks Bruno Oliveira.
-
-- updated plugin index docs. Thanks Bruno Oliveira.
-
-- fix issue557: with "-k" we only allow the old style "-" for negation
- at the beginning of strings and even that is deprecated. Use "not" instead.
- This should allow to pick parametrized tests where "-" appeared in the parameter.
-
-- fix issue604: Escape % character in the assertion message.
-
-- fix issue620: add explanation in the --genscript target about what
- the binary blob means. Thanks Dinu Gherman.
-
-- fix issue614: fixed pastebin support.
-

-- fix issue575: xunit-xml was reporting collection errors as failures
- instead of errors, thanks Oleg Sinyavskiy.
-
-- fix issue582: fix setuptools example, thanks Laszlo Papp and Ronny
- Pfannschmidt.
-
-- Fix infinite recursion bug when pickling capture.EncodedFile, thanks
- Uwe Schmitt.
-
-- fix issue589: fix bad interaction with numpy and others when showing
- exceptions. Check for precise "maximum recursion depth exceed" exception
- instead of presuming any RuntimeError is that one (implemented in py
- dep). Thanks Charles Cloud for analysing the issue.
-
-- fix conftest related fixture visibility issue: when running with a
- CWD outside a test package pytest would get fixture discovery wrong.
- Thanks to Wolfgang Schnerring for figuring out a reproducable example.
-
-- Introduce pytest_enter_pdb hook (needed e.g. by pytest_timeout to cancel the
- timeout when interactively entering pdb). Thanks Wolfgang Schnerring.
-
-- check xfail/skip also with non-python function test items. Thanks
- Floris Bruynooghe.
-
-2.6.2
-=====
-
-- Added function pytest.freeze_includes(), which makes it easy to embed
- pytest into executables using tools like cx_freeze.
- See docs for examples and rationale. Thanks Bruno Oliveira.
-
-- Improve assertion rewriting cache invalidation precision.
-
-- fixed issue561: adapt autouse fixture example for python3.
-
-- fixed issue453: assertion rewriting issue with __repr__ containing
- "\n{", "\n}" and "\n~".
-
-- fix issue560: correctly display code if an "else:" or "finally:" is
- followed by statements on the same line.
-
-- Fix example in monkeypatch documentation, thanks t-8ch.
-
-- fix issue572: correct tmpdir doc example for python3.
-
-- Do not mark as universal wheel because Python 2.6 is different from
- other builds due to the extra argparse dependency. Fixes issue566.
- Thanks sontek.
-
-- Implement issue549: user-provided assertion messages now no longer
- replace the py.test introspection message but are shown in addition
- to them.
-
-2.6.1
-=====
-
-- No longer show line numbers in the --verbose output, the output is now
- purely the nodeid. The line number is still shown in failure reports.
- Thanks Floris Bruynooghe.
-
-- fix issue437 where assertion rewriting could cause pytest-xdist slaves
- to collect different tests. Thanks Bruno Oliveira.
-
-- fix issue555: add "errors" attribute to capture-streams to satisfy
- some distutils and possibly other code accessing sys.stdout.errors.
-
-- fix issue547 capsys/capfd also work when output capturing ("-s") is disabled.
-
-- address issue170: allow pytest.mark.xfail(...) to specify expected exceptions via
- an optional "raises=EXC" argument where EXC can be a single exception
- or a tuple of exception classes. Thanks David Mohr for the complete
- PR.
-
-- fix integration of pytest with unittest.mock.patch decorator when
- it uses the "new" argument. Thanks Nicolas Delaby for test and PR.
-
-- fix issue with detecting conftest files if the arguments contain
- "::" node id specifications (copy pasted from "-v" output)
-
-- fix issue544 by only removing "@NUM" at the end of "::" separated parts
- and if the part has an ".py" extension
-
-- don't use py.std import helper, rather import things directly.
- Thanks Bruno Oliveira.
-
-2.6
-===
-
-- Cache exceptions from fixtures according to their scope (issue 467).
-
-- fix issue537: Avoid importing old assertion reinterpretation code by default.
-
-- fix issue364: shorten and enhance tracebacks representation by default.
- The new "--tb=auto" option (default) will only display long tracebacks
- for the first and last entry. You can get the old behaviour of printing
- all entries as long entries with "--tb=long". Also short entries by
- default are now printed very similarly to "--tb=native" ones.
-
-- fix issue514: teach assertion reinterpretation about private class attributes
-
-- change -v output to include full node IDs of tests. Users can copy
- a node ID from a test run, including line number, and use it as a
- positional argument in order to run only a single test.
-
-- fix issue 475: fail early and comprehensible if calling
- pytest.raises with wrong exception type.
-
-- fix issue516: tell in getting-started about current dependencies.
-
-- cleanup setup.py a bit and specify supported versions. Thanks Jurko
- Gospodnetic for the PR.
-
-- change XPASS colour to yellow rather then red when tests are run
- with -v.
-
-- fix issue473: work around mock putting an unbound method into a class
- dict when double-patching.
-
-- fix issue498: if a fixture finalizer fails, make sure that
- the fixture is still invalidated.
-
-- fix issue453: the result of the pytest_assertrepr_compare hook now gets
- it's newlines escaped so that format_exception does not blow up.
-
-- internal new warning system: pytest will now produce warnings when
- it detects oddities in your test collection or execution.
- Warnings are ultimately sent to a new pytest_logwarning hook which is
- currently only implemented by the terminal plugin which displays
- warnings in the summary line and shows more details when -rw (report on
- warnings) is specified.
-
-- change skips into warnings for test classes with an __init__ and
- callables in test modules which look like a test but are not functions.
-
-- fix issue436: improved finding of initial conftest files from command
- line arguments by using the result of parse_known_args rather than
- the previous flaky heuristics. Thanks Marc Abramowitz for tests
- and initial fixing approaches in this area.
-
-- fix issue #479: properly handle nose/unittest(2) SkipTest exceptions
- during collection/loading of test modules. Thanks to Marc Schlaich
- for the complete PR.
-
-- fix issue490: include pytest_load_initial_conftests in documentation
- and improve docstring.
-
-- fix issue472: clarify that ``pytest.config.getvalue()`` cannot work
- if it's triggered ahead of command line parsing.
-
-- merge PR123: improved integration with mock.patch decorator on tests.
-
-- fix issue412: messing with stdout/stderr FD-level streams is now
- captured without crashes.
-
-- fix issue483: trial/py33 works now properly. Thanks Daniel Grana for PR.
-
-- improve example for pytest integration with "python setup.py test"
- which now has a generic "-a" or "--pytest-args" option where you
- can pass additional options as a quoted string. Thanks Trevor Bekolay.
-
-- simplified internal capturing mechanism and made it more robust
- against tests or setups changing FD1/FD2, also better integrated
- now with pytest.pdb() in single tests.
-
-- improvements to pytest's own test-suite leakage detection, courtesy of PRs
- from Marc Abramowitz
-
-- fix issue492: avoid leak in test_writeorg. Thanks Marc Abramowitz.
-
-- fix issue493: don't run tests in doc directory with ``python setup.py test``
- (use tox -e doctesting for that)
-
-- fix issue486: better reporting and handling of early conftest loading failures
-
-- some cleanup and simplification of internal conftest handling.
-
-- work a bit harder to break reference cycles when catching exceptions.
- Thanks Jurko Gospodnetic.
-
-- fix issue443: fix skip examples to use proper comparison. Thanks Alex
- Groenholm.
-
-- support nose-style ``__test__`` attribute on modules, classes and
- functions, including unittest-style Classes. If set to False, the
- test will not be collected.
-
-- fix issue512: show "<notset>" for arguments which might not be set
- in monkeypatch plugin. Improves output in documentation.
-
-
-2.5.2
-=====
-
-- fix issue409 -- better interoperate with cx_freeze by not
- trying to import from collections.abc which causes problems
- for py27/cx_freeze. Thanks Wolfgang L. for reporting and tracking it down.
-
-- fixed docs and code to use "pytest" instead of "py.test" almost everywhere.
- Thanks Jurko Gospodnetic for the complete PR.
-
-- fix issue425: mention at end of "py.test -h" that --markers
- and --fixtures work according to specified test path (or current dir)
-
-- fix issue413: exceptions with unicode attributes are now printed
- correctly also on python2 and with pytest-xdist runs. (the fix
- requires py-1.4.20)
-
-- copy, cleanup and integrate py.io capture
- from pylib 1.4.20.dev2 (rev 13d9af95547e)
-
-- address issue416: clarify docs as to conftest.py loading semantics
-
-- fix issue429: comparing byte strings with non-ascii chars in assert
- expressions now work better. Thanks Floris Bruynooghe.
-
-- make capfd/capsys.capture private, its unused and shouldnt be exposed
-
-
-2.5.1
-=====
-
-- merge new documentation styling PR from Tobias Bieniek.
-
-- fix issue403: allow parametrize of multiple same-name functions within
- a collection node. Thanks Andreas Kloeckner and Alex Gaynor for reporting
- and analysis.
-
-- Allow parameterized fixtures to specify the ID of the parameters by
- adding an ids argument to pytest.fixture() and pytest.yield_fixture().
- Thanks Floris Bruynooghe.
-
-- fix issue404 by always using the binary xml escape in the junitxml
- plugin. Thanks Ronny Pfannschmidt.
-
-- fix issue407: fix addoption docstring to point to argparse instead of
- optparse. Thanks Daniel D. Wright.

-
-- dropped python2.5 from automated release testing of pytest itself
- which means it's probably going to break soon (but still works
- with this release we believe).
-
-- simplified and fixed implementation for calling finalizers when
- parametrized fixtures or function arguments are involved. finalization
- is now performed lazily at setup time instead of in the "teardown phase".
- While this might sound odd at first, it helps to ensure that we are
- correctly handling setup/teardown even in complex code. User-level code
- should not be affected unless it's implementing the pytest_runtest_teardown
- hook and expecting certain fixture instances are torn down within (very
- unlikely and would have been unreliable anyway).
-
-- PR90: add --color=yes|no|auto option to force terminal coloring
- mode ("auto" is default). Thanks Marc Abramowitz.
-
-- fix issue319 - correctly show unicode in assertion errors. Many
- thanks to Floris Bruynooghe for the complete PR. Also means
- we depend on py>=1.4.19 now.
-
-- fix issue396 - correctly sort and finalize class-scoped parametrized
- tests independently from number of methods on the class.
-
-- refix issue323 in a better way -- parametrization should now never
- cause Runtime Recursion errors because the underlying algorithm
- for re-ordering tests per-scope/per-fixture is not recursive
- anymore (it was tail-call recursive before which could lead
- to problems for more than >966 non-function scoped parameters).
-
-- fix issue290 - there is preliminary support now for parametrizing
- with repeated same values (sometimes useful to to test if calling
- a second time works as with the first time).
-
-- close issue240 - document precisely how pytest module importing
- works, discuss the two common test directory layouts, and how it
- interacts with PEP420-namespace packages.
-
-- fix issue246 fix finalizer order to be LIFO on independent fixtures
- depending on a parametrized higher-than-function scoped fixture.
- (was quite some effort so please bear with the complexity of this sentence :)
- Thanks Ralph Schmitt for the precise failure example.
-
-- fix issue244 by implementing special index for parameters to only use
- indices for paramentrized test ids
-
-- fix issue287 by running all finalizers but saving the exception
- from the first failing finalizer and re-raising it so teardown will
- still have failed. We reraise the first failing exception because
- it might be the cause for other finalizers to fail.
-
-- fix ordering when mock.patch or other standard decorator-wrappings
- are used with test methods. This fixues issue346 and should
- help with random "xdist" collection failures. Thanks to
- Ronny Pfannschmidt and Donald Stufft for helping to isolate it.
-
-- fix issue357 - special case "-k" expressions to allow for
- filtering with simple strings that are not valid python expressions.
- Examples: "-k 1.3" matches all tests parametrized with 1.3.
- "-k None" filters all tests that have "None" in their name
- and conversely "-k 'not None'".
- Previously these examples would raise syntax errors.
-
-- fix issue384 by removing the trial support code
- since the unittest compat enhancements allow
- trial to handle it on its own
-
-- don't hide an ImportError when importing a plugin produces one.
- fixes issue375.
-
-- fix issue275 - allow usefixtures and autouse fixtures
- for running doctest text files.
-
-- fix issue380 by making --resultlog only rely on longrepr instead
- of the "reprcrash" attribute which only exists sometimes.
-
-- address issue122: allow @pytest.fixture(params=iterator) by exploding
- into a list early on.
-
-- fix pexpect-3.0 compatibility for pytest's own tests.
- (fixes issue386)
-
-- allow nested parametrize-value markers, thanks James Lan for the PR.
-
-- fix unicode handling with new monkeypatch.setattr(import_path, value)
- API. Thanks Rob Dennis. Fixes issue371.
-
-- fix unicode handling with junitxml, fixes issue368.
-
-- In assertion rewriting mode on Python 2, fix the detection of coding
- cookies. See issue #330.
-
-- make "--runxfail" turn imperative pytest.xfail calls into no ops
- (it already did neutralize pytest.mark.xfail markers)
-
-- refine pytest / pkg_resources interactions: The AssertionRewritingHook
- PEP302 compliant loader now registers itself with setuptools/pkg_resources
- properly so that the pkg_resources.resource_stream method works properly.
- Fixes issue366. Thanks for the investigations and full PR to Jason R. Coombs.
-
-- pytestconfig fixture is now session-scoped as it is the same object during the
- whole test run. Fixes issue370.
-
-- avoid one surprising case of marker malfunction/confusion::
-
- @pytest.mark.some(lambda arg: ...)
- def test_function():
-
- would not work correctly because pytest assumes @pytest.mark.some
- gets a function to be decorated already. We now at least detect if this
- arg is an lambda and thus the example will work. Thanks Alex Gaynor
- for bringing it up.
-
-- xfail a test on pypy that checks wrong encoding/ascii (pypy does
- not error out). fixes issue385.
-
-- internally make varnames() deal with classes's __init__,
- although it's not needed by pytest itself atm. Also
- fix caching. Fixes issue376.
-
-- fix issue221 - handle importing of namespace-package with no
- __init__.py properly.
-
-- refactor internal FixtureRequest handling to avoid monkeypatching.
- One of the positive user-facing effects is that the "request" object
- can now be used in closures.
-
-- fixed version comparison in pytest.importskip(modname, minverstring)
-
-- fix issue377 by clarifying in the nose-compat docs that pytest
- does not duplicate the unittest-API into the "plain" namespace.
-
-- fix verbose reporting for @mock'd test functions
-
-2.4.2
-=====
-
-- on Windows require colorama and a newer py lib so that py.io.TerminalWriter()
- now uses colorama instead of its own ctypes hacks. (fixes issue365)
- thanks Paul Moore for bringing it up.
-
-- fix "-k" matching of tests where "repr" and "attr" and other names would
- cause wrong matches because of an internal implementation quirk
- (don't ask) which is now properly implemented. fixes issue345.
-
-- avoid tmpdir fixture to create too long filenames especially
- when parametrization is used (issue354)
-
-- fix pytest-pep8 and pytest-flakes / pytest interactions
- (collection names in mark plugin was assuming an item always
- has a function which is not true for those plugins etc.)
- Thanks Andi Zeidler.
-
-- introduce node.get_marker/node.add_marker API for plugins
- like pytest-pep8 and pytest-flakes to avoid the messy
- details of the node.keywords pseudo-dicts. Adapted
- docs.
-
-- remove attempt to "dup" stdout at startup as it's icky.
- the normal capturing should catch enough possibilities
- of tests messing up standard FDs.
-
-- add pluginmanager.do_configure(config) as a link to
- config.do_configure() for plugin-compatibility
-
-2.4.1
-=====
-
-- When using parser.addoption() unicode arguments to the
- "type" keyword should also be converted to the respective types.
- thanks Floris Bruynooghe, @dnozay. (fixes issue360 and issue362)
-
-- fix dotted filename completion when using argcomplete
- thanks Anthon van der Neuth. (fixes issue361)
-
-- fix regression when a 1-tuple ("arg",) is used for specifying
- parametrization (the values of the parametrization were passed
- nested in a tuple). Thanks Donald Stufft.
-
-- merge doc typo fixes, thanks Andy Dirnberger
-
-2.4
-===
-
-known incompatibilities:
-
-- if calling --genscript from python2.7 or above, you only get a
- standalone script which works on python2.7 or above. Use Python2.6
- to also get a python2.5 compatible version.
-
-- all xunit-style teardown methods (nose-style, pytest-style,
- unittest-style) will not be called if the corresponding setup method failed,
- see issue322 below.
-
-- the pytest_plugin_unregister hook wasn't ever properly called
- and there is no known implementation of the hook - so it got removed.
-
-- pytest.fixture-decorated functions cannot be generators (i.e. use
- yield) anymore. This change might be reversed in 2.4.1 if it causes
- unforeseen real-life issues. However, you can always write and return
- an inner function/generator and change the fixture consumer to iterate
- over the returned generator. This change was done in lieu of the new
- ``pytest.yield_fixture`` decorator, see below.
-
-new features:
-
-- experimentally introduce a new ``pytest.yield_fixture`` decorator
- which accepts exactly the same parameters as pytest.fixture but
- mandates a ``yield`` statement instead of a ``return statement`` from
- fixture functions. This allows direct integration with "with-style"
- context managers in fixture functions and generally avoids registering
- of finalization callbacks in favour of treating the "after-yield" as
- teardown code. Thanks Andreas Pelme, Vladimir Keleshev, Floris
- Bruynooghe, Ronny Pfannschmidt and many others for discussions.
-
-- allow boolean expression directly with skipif/xfail
- if a "reason" is also specified. Rework skipping documentation
- to recommend "condition as booleans" because it prevents surprises
- when importing markers between modules. Specifying conditions
- as strings will remain fully supported.
-
-- reporting: color the last line red or green depending if
- failures/errors occurred or everything passed. thanks Christian
- Theunert.
-
-- make "import pdb ; pdb.set_trace()" work natively wrt capturing (no
- "-s" needed anymore), making ``pytest.set_trace()`` a mere shortcut.
-
-- fix issue181: --pdb now also works on collect errors (and
- on internal errors) . This was implemented by a slight internal
- refactoring and the introduction of a new hook
- ``pytest_exception_interact`` hook (see next item).
-
-- fix issue341: introduce new experimental hook for IDEs/terminals to
- intercept debugging: ``pytest_exception_interact(node, call, report)``.
-
-- new monkeypatch.setattr() variant to provide a shorter
- invocation for patching out classes/functions from modules:
-
- monkeypatch.setattr("requests.get", myfunc)
-
- will replace the "get" function of the "requests" module with ``myfunc``.
-
-- fix issue322: tearDownClass is not run if setUpClass failed. Thanks
- Mathieu Agopian for the initial fix. Also make all of pytest/nose
- finalizer mimick the same generic behaviour: if a setupX exists and
- fails, don't run teardownX. This internally introduces a new method
- "node.addfinalizer()" helper which can only be called during the setup
- phase of a node.
-
-- simplify pytest.mark.parametrize() signature: allow to pass a
- CSV-separated string to specify argnames. For example:
- ``pytest.mark.parametrize("input,expected", [(1,2), (2,3)])``
- works as well as the previous:
- ``pytest.mark.parametrize(("input", "expected"), ...)``.
-
-- add support for setUpModule/tearDownModule detection, thanks Brian Okken.
-
-- integrate tab-completion on options through use of "argcomplete".
- Thanks Anthon van der Neut for the PR.
-
-- change option names to be hyphen-separated long options but keep the
- old spelling backward compatible. py.test -h will only show the
- hyphenated version, for example "--collect-only" but "--collectonly"
- will remain valid as well (for backward-compat reasons). Many thanks to
- Anthon van der Neut for the implementation and to Hynek Schlawack for
- pushing us.
-
-- fix issue 308 - allow to mark/xfail/skip individual parameter sets
- when parametrizing. Thanks Brianna Laugher.
-
-- call new experimental pytest_load_initial_conftests hook to allow
- 3rd party plugins to do something before a conftest is loaded.
-
-Bug fixes:
-
-- fix issue358 - capturing options are now parsed more properly
- by using a new parser.parse_known_args method.
-
-- pytest now uses argparse instead of optparse (thanks Anthon) which
- means that "argparse" is added as a dependency if installing into python2.6
- environments or below.
-
-- fix issue333: fix a case of bad unittest/pytest hook interaction.

-
-- fix issue320 - fix class scope for fixtures when mixed with
- module-level functions. Thanks Anatloy Bubenkoff.
-
-- you can specify "-q" or "-qq" to get different levels of "quieter"
- reporting (thanks Katarzyna Jachim)
-
-- fix issue300 - Fix order of conftest loading when starting py.test
- in a subdirectory.
-

- session start (helps fix plugin behaviour which write output files
- with relative path such as pytest-cov)
-
-- fix issue316 - properly reference collection hooks in docs
-
-- fix issue 306 - cleanup of -k/-m options to only match markers/test
- names/keywords respectively. Thanks Wouter van Ackooy.
-
-- improved doctest counting for doctests in python modules --
- files without any doctest items will not show up anymore
- and doctest examples are counted as separate test items.
- thanks Danilo Bellini.
-
-- fix issue245 by depending on the released py-1.4.14
- which fixes py.io.dupfile to work with files with no
- mode. Thanks Jason R. Coombs.

-
-- issue 251 - report a skip instead of ignoring classes with init
-
-- issue250 unicode/str mixes in parametrization names and values now works

-
-- fix issue266 - accept unicode in MarkEvaluator expressions
-
-2.3.4
-=====
-
-- yielded test functions will now have autouse-fixtures active but
- cannot accept fixtures as funcargs - it's anyway recommended to
- rather use the post-2.0 parametrize features instead of yield, see:
- http://pytest.org/latest/example/parametrize.html

-- fix issue91 - add/discuss package/directory level setups in example
-- allow to dynamically define markers via
- item.keywords[...]=assignment integrating with "-m" option
-- make "-k" accept an expressions the same as with "-m" so that one
- can write: -k "name1 or name2" etc. This is a slight incompatibility
- if you used special syntax like "TestClass.test_method" which you now
- need to write as -k "TestClass and test_method" to match a certain
- method in a certain test class.
-
-2.3.3

- bits are properly distributed for maintainers who run pytest-own tests
-
-2.3.1
-=====
-
-- fix issue202 - fix regression: using "self" from fixture functions now
- works as expected (it's the same "self" instance that a test method
- which uses the fixture sees)
-
-- skip pexpect using tests (test_pdb.py mostly) on freebsd* systems
- due to pexpect not supporting it properly (hanging)
-
-- link to web pages from --markers output which provides help for
- pytest.mark.* usage.

-- catch unicode-issues when writing failure representations
- to terminal to prevent the whole session from crashing

-- fix issue 191: add unittest TestCase runTest method support
-- fix issue 156: monkeypatch correctly handles class level descriptors
-
-- reporting refinements:
-

- you can use startdir.bestrelpath(yourpath) to show
- nice relative path
-
- - allow plugins to implement both pytest_report_header and
- pytest_sessionstart (sessionstart is invoked first).
-
- - don't show deselected reason line if there is none

- produce better output
-- fix issue102: report more useful errors and hints for when a
- test directory was renamed and some pyc/__pycache__ remain
-- fix issue106: allow parametrize to be applied multiple times
- e.g. from module, class and at function level.

-2.2.1
-=====
-
-- fix issue99 (in pytest and py) internallerrors with resultlog now
- produce better output - fixed by normalizing pytest_internalerror
- input arguments.
-- fix issue97 / traceback issues (in pytest and py) improve traceback output
- in conjunction with jinja2 and cython which hack tracebacks
-- fix issue93 (in pytest and pytest-xdist) avoid "delayed teardowns":
- the final test in a test node will now run its teardown directly
- instead of waiting for the end of the session. Thanks Dave Hunt for
- the good reporting and feedback. The pytest_runtest_protocol as well
- as the pytest_runtest_teardown hooks now have "nextitem" available
- which will be None indicating the end of the test run.
-- fix collection crash due to unknown-source collected items, thanks
- to Ralf Schmitt (fixed by depending on a more recent pylib)
-
-2.2.0
-=====
-
-- fix issue90: introduce eager tearing down of test items so that
- teardown function are called earlier.
-- add an all-powerful metafunc.parametrize function which allows to
- parametrize test function arguments in multiple steps and therefore
- from indepdenent plugins and palces.
-- add a @pytest.mark.parametrize helper which allows to easily
- call a test function with different argument values
-- Add examples to the "parametrize" example page, including a quick port
- of Test scenarios and the new parametrize function and decorator.
-- introduce registration for "pytest.mark.*" helpers via ini-files
- or through plugin hooks. Also introduce a "--strict" option which
- will treat unregistered markers as errors
- allowing to avoid typos and maintain a well described set of markers
- for your test suite. See exaples at http://pytest.org/latest/mark.html
- and its links.
-- issue50: introduce "-m marker" option to select tests based on markers
- (this is a stricter and more predictable version of '-k' in that "-m"
- only matches complete markers and has more obvious rules for and/or
- semantics.
-- new feature to help optimizing the speed of your tests:
- --durations=N option for displaying N slowest test calls
- and setup/teardown methods.
-- fix issue87: --pastebin now works with python3

-
-2.1.0
-=====
-
-- fix issue53 call nosestyle setup functions with correct ordering
-- fix issue58 and issue59: new assertion code fixes
-- merge Benjamin's assertionrewrite branch: now assertions
- for test modules on python 2.6 and above are done by rewriting
- the AST and saving the pyc file before the test module is imported.
- see doc/assert.txt for more info.
-- fix issue43: improve doctests with better traceback reporting on
- unexpected exceptions
-- fix issue47: timing output in junitxml for test cases is now correct
-- fix issue48: typo in MarkInfo repr leading to exception
-- fix issue49: avoid confusing error when initizaliation partially fails
-- fix issue44: env/username expansion for junitxml file path
-- show releaselevel information in test runs for pypy
-- reworked doc pages for better navigation and PDF generation
-- report KeyboardInterrupt even if interrupted during session startup
-- fix issue 35 - provide PDF doc version and download link from index page
-
-2.0.3
-=====
-
-- fix issue38: nicer tracebacks on calls to hooks, particularly early
- configure/sessionstart ones
-
-- fix missing skip reason/meta information in junitxml files, reported
- via http://lists.idyll.org/pipermail/testing-in-python/2011-March/003928.html
-
-- fix issue34: avoid collection failure with "test" prefixed classes
- deriving from object.
-
-- don't require zlib (and other libs) for genscript plugin without
- --genscript actually being used.
-
-- speed up skips (by not doing a full traceback represenation
- internally)
-
-- fix issue37: avoid invalid characters in junitxml's output
-
-2.0.2
-=====
-
-- tackle issue32 - speed up test runs of very quick test functions
- by reducing the relative overhead
-
-- fix issue30 - extended xfail/skipif handling and improved reporting.
- If you have a syntax error in your skip/xfail
- expressions you now get nice error reports.
-
- Also you can now access module globals from xfail/skipif
- expressions so that this for example works now::
-
- import pytest
- import mymodule
- @pytest.mark.skipif("mymodule.__version__[0] == "1")
- def test_function():
- pass
-
- This will not run the test function if the module's version string
- does not start with a "1". Note that specifying a string instead
- of a boolean expressions allows py.test to report meaningful information
- when summarizing a test run as to what conditions lead to skipping
- (or xfail-ing) tests.
-
-- fix issue28 - setup_method and pytest_generate_tests work together
- The setup_method fixture method now gets called also for
- test function invocations generated from the pytest_generate_tests
- hook.
-
-- fix issue27 - collectonly and keyword-selection (-k) now work together
- Also, if you do "py.test --collectonly -q" you now get a flat list
- of test ids that you can use to paste to the py.test commandline
- in order to execute a particular test.
-
-- fix issue25 avoid reported problems with --pdb and python3.2/encodings output
-
-- fix issue23 - tmpdir argument now works on Python3.2 and WindowsXP
- Starting with Python3.2 os.symlink may be supported. By requiring
- a newer py lib version the py.path.local() implementation acknowledges
- this.
-
-- fixed typos in the docs (thanks Victor Garcia, Brianna Laugher) and particular
- thanks to Laura Creighton who also revieved parts of the documentation.
-
-- fix slighly wrong output of verbose progress reporting for classes
- (thanks Amaury)
-
-- more precise (avoiding of) deprecation warnings for node.Class|Function accesses
-
-- avoid std unittest assertion helper code in tracebacks (thanks Ronny)
-
-2.0.1
-=====
-
-- refine and unify initial capturing so that it works nicely
- even if the logging module is used on an early-loaded conftest.py
- file or plugin.
-- allow to omit "()" in test ids to allow for uniform test ids
- as produced by Alfredo's nice pytest.vim plugin.
-- fix issue12 - show plugin versions with "--version" and
- "--traceconfig" and also document how to add extra information
- to reporting test header
-- fix issue17 (import-* reporting issue on python3) by
- requiring py>1.4.0 (1.4.1 is going to include it)
-- fix issue10 (numpy arrays truth checking) by refining
- assertion interpretation in py lib
-- fix issue15: make nose compatibility tests compatible
- with python3 (now that nose-1.0 supports python3)
-- remove somewhat surprising "same-conftest" detection because
- it ignores conftest.py when they appear in several subdirs.
-- improve assertions ("not in"), thanks Floris Bruynooghe
-- improve behaviour/warnings when running on top of "python -OO"
- (assertions and docstrings are turned off, leading to potential
- false positives)
-- introduce a pytest_cmdline_processargs(args) hook
- to allow dynamic computation of command line arguments.
- This fixes a regression because py.test prior to 2.0
- allowed to set command line options from conftest.py
- files which so far pytest-2.0 only allowed from ini-files now.
-- fix issue7: assert failures in doctest modules.
- unexpected failures in doctests will not generally
- show nicer, i.e. within the doctest failing context.
-- fix issue9: setup/teardown functions for an xfail-marked
- test will report as xfail if they fail but report as normally
- passing (not xpassing) if they succeed. This only is true
- for "direct" setup/teardown invocations because teardown_class/
- teardown_module cannot closely relate to a single test.
-- fix issue14: no logging errors at process exit
-- refinements to "collecting" output on non-ttys
-- refine internal plugin registration and --traceconfig output
-- introduce a mechanism to prevent/unregister plugins from the
- command line, see http://pytest.org/plugins.html#cmdunregister
-- activate resultlog plugin by default
-- fix regression wrt yielded tests which due to the
- collection-before-running semantics were not
- setup as with pytest 1.3.4. Note, however, that
- the recommended and much cleaner way to do test
- parametraization remains the "pytest_generate_tests"
- mechanism, see the docs.
-
-2.0.0
-=====
-
-- pytest-2.0 is now its own package and depends on pylib-2.0
-- new ability: python -m pytest / python -m pytest.main ability
-- new python invcation: pytest.main(args, plugins) to load
- some custom plugins early.
-- try harder to run unittest test suites in a more compatible manner
- by deferring setup/teardown semantics to the unittest package.
- also work harder to run twisted/trial and Django tests which
- should now basically work by default.
-- introduce a new way to set config options via ini-style files,
- by default setup.cfg and tox.ini files are searched. The old
- ways (certain environment variables, dynamic conftest.py reading
- is removed).
-- add a new "-q" option which decreases verbosity and prints a more
- nose/unittest-style "dot" output.
-- fix issue135 - marks now work with unittest test cases as well
-- fix issue126 - introduce py.test.set_trace() to trace execution via
- PDB during the running of tests even if capturing is ongoing.
-- fix issue123 - new "python -m py.test" invocation for py.test
- (requires Python 2.5 or above)
-- fix issue124 - make reporting more resilient against tests opening
- files on filedescriptor 1 (stdout).
-- fix issue109 - sibling conftest.py files will not be loaded.
- (and Directory collectors cannot be customized anymore from a Directory's
- conftest.py - this needs to happen at least one level up).
-- introduce (customizable) assertion failure representations and enhance
- output on assertion failures for comparisons and other cases (Floris Bruynooghe)
-- nose-plugin: pass through type-signature failures in setup/teardown
- functions instead of not calling them (Ed Singleton)
-- remove py.test.collect.Directory (follows from a major refactoring
- and simplification of the collection process)
-- majorly reduce py.test core code, shift function/python testing to own plugin
-- fix issue88 (finding custom test nodes from command line arg)
-- refine 'tmpdir' creation, will now create basenames better associated
- with test names (thanks Ronny)
-- "xpass" (unexpected pass) tests don't cause exitcode!=0
-- fix issue131 / issue60 - importing doctests in __init__ files used as namespace packages
-- fix issue93 stdout/stderr is captured while importing conftest.py
-- fix bug: unittest collected functions now also can have "pytestmark"
- applied at class/module level
-- add ability to use "class" level for cached_setup helper
-- fix strangeness: mark.* objects are now immutable, create new instances
-
-1.3.4
-=====
-
-- fix issue111: improve install documentation for windows
-- fix issue119: fix custom collectability of __init__.py as a module
-- fix issue116: --doctestmodules work with __init__.py files as well
-- fix issue115: unify internal exception passthrough/catching/GeneratorExit
-- fix issue118: new --tb=native for presenting cpython-standard exceptions
-
-1.3.3
-=====
-
-- fix issue113: assertion representation problem with triple-quoted strings
- (and possibly other cases)
-- make conftest loading detect that a conftest file with the same
- content was already loaded, avoids surprises in nested directory structures
- which can be produced e.g. by Hudson. It probably removes the need to use
- --confcutdir in most cases.
-- fix terminal coloring for win32
- (thanks Michael Foord for reporting)
-- fix weirdness: make terminal width detection work on stdout instead of stdin
- (thanks Armin Ronacher for reporting)
-- remove trailing whitespace in all py/text distribution files
-
-1.3.2
-=====
-
-**New features**
-
-- fix issue103: introduce py.test.raises as context manager, examples::
-
- with py.test.raises(ZeroDivisionError):
- x = 0
- 1 / x
-
- with py.test.raises(RuntimeError) as excinfo:
- call_something()
-
- # you may do extra checks on excinfo.value|type|traceback here
-
- (thanks Ronny Pfannschmidt)
-
-- Funcarg factories can now dynamically apply a marker to a
- test invocation. This is for example useful if a factory
- provides parameters to a test which are expected-to-fail::
-
- def pytest_funcarg__arg(request):
- request.applymarker(py.test.mark.xfail(reason="flaky config"))
- ...
-
- def test_function(arg):
- ...
-
-- improved error reporting on collection and import errors. This makes
- use of a more general mechanism, namely that for custom test item/collect
- nodes ``node.repr_failure(excinfo)`` is now uniformly called so that you can
- override it to return a string error representation of your choice
- which is going to be reported as a (red) string.
-
-- introduce '--junitprefix=STR' option to prepend a prefix
- to all reports in the junitxml file.
-
-**Bug fixes**
-
-- make tests and the ``pytest_recwarn`` plugin in particular fully compatible
- to Python2.7 (if you use the ``recwarn`` funcarg warnings will be enabled so that
- you can properly check for their existence in a cross-python manner).
-- refine --pdb: ignore xfailed tests, unify its TB-reporting and
- don't display failures again at the end.
-- fix assertion interpretation with the ** operator (thanks Benjamin Peterson)
-- fix issue105 assignment on the same line as a failing assertion (thanks Benjamin Peterson)
-- fix issue104 proper escaping for test names in junitxml plugin (thanks anonymous)
-- fix issue57 -f|--looponfail to work with xpassing tests (thanks Ronny)
-- fix issue92 collectonly reporter and --pastebin (thanks Benjamin Peterson)
-- fix py.code.compile(source) to generate unique filenames
-- fix assertion re-interp problems on PyPy, by defering code
- compilation to the (overridable) Frame.eval class. (thanks Amaury Forgeot)
-- fix py.path.local.pyimport() to work with directories
-- streamline py.path.local.mkdtemp implementation and usage
-- don't print empty lines when showing junitxml-filename
-- add optional boolean ignore_errors parameter to py.path.local.remove
-- fix terminal writing on win32/python2.4
-- py.process.cmdexec() now tries harder to return properly encoded unicode objects
- on all python versions
-- install plain py.test/py.which scripts also for Jython, this helps to
- get canonical script paths in virtualenv situations
-- make path.bestrelpath(path) return ".", note that when calling
- X.bestrelpath the assumption is that X is a directory.
-- make initial conftest discovery ignore "--" prefixed arguments
-- fix resultlog plugin when used in an multicpu/multihost xdist situation
- (thanks Jakub Gustak)
-- perform distributed testing related reporting in the xdist-plugin
- rather than having dist-related code in the generic py.test
- distribution
-- fix homedir detection on Windows
-- ship distribute_setup.py version 0.6.13
-
-1.3.1
-=====
-
-**New features**
-
-- issue91: introduce new py.test.xfail(reason) helper
- to imperatively mark a test as expected to fail. Can
- be used from within setup and test functions. This is
- useful especially for parametrized tests when certain
- configurations are expected-to-fail. In this case the
- declarative approach with the @py.test.mark.xfail cannot
- be used as it would mark all configurations as xfail.
-
-- issue102: introduce new --maxfail=NUM option to stop
- test runs after NUM failures. This is a generalization
- of the '-x' or '--exitfirst' option which is now equivalent
- to '--maxfail=1'. Both '-x' and '--maxfail' will
- now also print a line near the end indicating the Interruption.
-
-- issue89: allow py.test.mark decorators to be used on classes
- (class decorators were introduced with python2.6) and
- also allow to have multiple markers applied at class/module level
- by specifying a list.
-
-- improve and refine letter reporting in the progress bar:
- . pass
- f failed test
- s skipped tests (reminder: use for dependency/platform mismatch only)
- x xfailed test (test that was expected to fail)
- X xpassed test (test that was expected to fail but passed)
-
- You can use any combination of 'fsxX' with the '-r' extended
- reporting option. The xfail/xpass results will show up as
- skipped tests in the junitxml output - which also fixes
- issue99.
-
-- make py.test.cmdline.main() return the exitstatus instead of raising
- SystemExit and also allow it to be called multiple times. This of
- course requires that your application and tests are properly teared
- down and don't have global state.
-
-**Bug Fixes**
-
-- improved traceback presentation:
- - improved and unified reporting for "--tb=short" option
- - Errors during test module imports are much shorter, (using --tb=short style)
- - raises shows shorter more relevant tracebacks
- - --fulltrace now more systematically makes traces longer / inhibits cutting
-
-- improve support for raises and other dynamically compiled code by
- manipulating python's linecache.cache instead of the previous
- rather hacky way of creating custom code objects. This makes
- it seemlessly work on Jython and PyPy where it previously didn't.
-
-- fix issue96: make capturing more resilient against Control-C
- interruptions (involved somewhat substantial refactoring
- to the underlying capturing functionality to avoid race
- conditions).
-
-- fix chaining of conditional skipif/xfail decorators - so it works now
- as expected to use multiple @py.test.mark.skipif(condition) decorators,
- including specific reporting which of the conditions lead to skipping.
-
-- fix issue95: late-import zlib so that it's not required
- for general py.test startup.
-
-- fix issue94: make reporting more robust against bogus source code
- (and internally be more careful when presenting unexpected byte sequences)
-
-
-1.3.0
-=====
-
-- deprecate --report option in favour of a new shorter and easier to
- remember -r option: it takes a string argument consisting of any
- combination of 'xfsX' characters. They relate to the single chars
- you see during the dotted progress printing and will print an extra line
- per test at the end of the test run. This extra line indicates the exact
- position or test ID that you directly paste to the py.test cmdline in order
- to re-run a particular test.
-
-- allow external plugins to register new hooks via the new
- pytest_addhooks(pluginmanager) hook. The new release of
- the pytest-xdist plugin for distributed and looponfailing
- testing requires this feature.
-
-- add a new pytest_ignore_collect(path, config) hook to allow projects and
- plugins to define exclusion behaviour for their directory structure -
- for example you may define in a conftest.py this method::
-
- def pytest_ignore_collect(path):
- return path.check(link=1)
-
- to prevent even a collection try of any tests in symlinked dirs.
-
-- new pytest_pycollect_makemodule(path, parent) hook for
- allowing customization of the Module collection object for a
- matching test module.
-
-- extend and refine xfail mechanism:
- ``@py.test.mark.xfail(run=False)`` do not run the decorated test
- ``@py.test.mark.xfail(reason="...")`` prints the reason string in xfail summaries
- specifiying ``--runxfail`` on command line virtually ignores xfail markers
-
-- expose (previously internal) commonly useful methods:
- py.io.get_terminal_with() -> return terminal width
- py.io.ansi_print(...) -> print colored/bold text on linux/win32
- py.io.saferepr(obj) -> return limited representation string
-
-- expose test outcome related exceptions as py.test.skip.Exception,
- py.test.raises.Exception etc., useful mostly for plugins
- doing special outcome interpretation/tweaking
-
-- (issue85) fix junitxml plugin to handle tests with non-ascii output
-
-- fix/refine python3 compatibility (thanks Benjamin Peterson)
-
-- fixes for making the jython/win32 combination work, note however:
- jython2.5.1/win32 does not provide a command line launcher, see
- http://bugs.jython.org/issue1491 . See pylib install documentation
- for how to work around.
-
-- fixes for handling of unicode exception values and unprintable objects
-
-- (issue87) fix unboundlocal error in assertionold code
-
-- (issue86) improve documentation for looponfailing
-
-- refine IO capturing: stdin-redirect pseudo-file now has a NOP close() method
-
-- ship distribute_setup.py version 0.6.10
-
-- added links to the new capturelog and coverage plugins
-
-
-1.2.0
-=====
-
-- refined usage and options for "py.cleanup"::
-
- py.cleanup # remove "*.pyc" and "*$py.class" (jython) files
- py.cleanup -e .swp -e .cache # also remove files with these extensions
- py.cleanup -s # remove "build" and "dist" directory next to setup.py files
- py.cleanup -d # also remove empty directories
- py.cleanup -a # synonym for "-s -d -e 'pip-log.txt'"
- py.cleanup -n # dry run, only show what would be removed
-
-- add a new option "py.test --funcargs" which shows available funcargs
- and their help strings (docstrings on their respective factory function)
- for a given test path
-
-- display a short and concise traceback if a funcarg lookup fails
-
-- early-load "conftest.py" files in non-dot first-level sub directories.
- allows to conveniently keep and access test-related options in a ``test``
- subdir and still add command line options.
-
-- fix issue67: new super-short traceback-printing option: "--tb=line" will print a single line for each failing (python) test indicating its filename, lineno and the failure value
-
-- fix issue78: always call python-level teardown functions even if the
- according setup failed. This includes refinements for calling setup_module/class functions
- which will now only be called once instead of the previous behaviour where they'd be called
- multiple times if they raise an exception (including a Skipped exception). Any exception
- will be re-corded and associated with all tests in the according module/class scope.
-
-- fix issue63: assume <40 columns to be a bogus terminal width, default to 80
-
-- fix pdb debugging to be in the correct frame on raises-related errors
-
-- update apipkg.py to fix an issue where recursive imports might
- unnecessarily break importing
-
-- fix plugin links
-
-1.1.1
-=====
-
-- moved dist/looponfailing from py.test core into a new
- separately released pytest-xdist plugin.
-
-- new junitxml plugin: --junitxml=path will generate a junit style xml file
- which is processable e.g. by the Hudson CI system.
-
-- new option: --genscript=path will generate a standalone py.test script
- which will not need any libraries installed. thanks to Ralf Schmitt.
-
-- new option: --ignore will prevent specified path from collection.
- Can be specified multiple times.
-
-- new option: --confcutdir=dir will make py.test only consider conftest
- files that are relative to the specified dir.
-
-- new funcarg: "pytestconfig" is the pytest config object for access
- to command line args and can now be easily used in a test.
-
-- install ``py.test`` and ``py.which`` with a ``-$VERSION`` suffix to
- disambiguate between Python3, python2.X, Jython and PyPy installed versions.
-
-- new "pytestconfig" funcarg allows access to test config object
-
-- new "pytest_report_header" hook can return additional lines
- to be displayed at the header of a test run.
-
-- (experimental) allow "py.test path::name1::name2::..." for pointing
- to a test within a test collection directly. This might eventually
- evolve as a full substitute to "-k" specifications.
-
-- streamlined plugin loading: order is now as documented in
- customize.html: setuptools, ENV, commandline, conftest.
- also setuptools entry point names are turned to canonical namees ("pytest_*")
-
-- automatically skip tests that need 'capfd' but have no os.dup
-
-- allow pytest_generate_tests to be defined in classes as well
-
-- deprecate usage of 'disabled' attribute in favour of pytestmark
-- deprecate definition of Directory, Module, Class and Function nodes
- in conftest.py files. Use pytest collect hooks instead.
-
-- collection/item node specific runtest/collect hooks are only called exactly
- on matching conftest.py files, i.e. ones which are exactly below
- the filesystem path of an item
-
-- change: the first pytest_collect_directory hook to return something
- will now prevent further hooks to be called.
-
-- change: figleaf plugin now requires --figleaf to run. Also
- change its long command line options to be a bit shorter (see py.test -h).
-
-- change: pytest doctest plugin is now enabled by default and has a
- new option --doctest-glob to set a pattern for file matches.
-
-- change: remove internal py._* helper vars, only keep py._pydir
-
-- robustify capturing to survive if custom pytest_runtest_setup
- code failed and prevented the capturing setup code from running.
-
-- make py.test.* helpers provided by default plugins visible early -
- works transparently both for pydoc and for interactive sessions
- which will regularly see e.g. py.test.mark and py.test.importorskip.
-
-- simplify internal plugin manager machinery
-- simplify internal collection tree by introducing a RootCollector node
-
-- fix assert reinterpreation that sees a call containing "keyword=..."
-
-- fix issue66: invoke pytest_sessionstart and pytest_sessionfinish
- hooks on slaves during dist-testing, report module/session teardown
- hooks correctly.
-
-- fix issue65: properly handle dist-testing if no
- execnet/py lib installed remotely.
-
-- skip some install-tests if no execnet is available
-
-- fix docs, fix internal bin/ script generation
-
-
-1.1.0
-=====
-
-- introduce automatic plugin registration via 'pytest11'
- entrypoints via setuptools' pkg_resources.iter_entry_points
-
-- fix py.test dist-testing to work with execnet >= 1.0.0b4
-
-- re-introduce py.test.cmdline.main() for better backward compatibility
-
-- svn paths: fix a bug with path.check(versioned=True) for svn paths,
- allow '%' in svn paths, make svnwc.update() default to interactive mode
- like in 1.0.x and add svnwc.update(interactive=False) to inhibit interaction.
-
-- refine distributed tarball to contain test and no pyc files
-
-- try harder to have deprecation warnings for py.compat.* accesses
- report a correct location
-
-1.0.3
-=====
-
-* adjust and improve docs
-
-* remove py.rest tool and internal namespace - it was
- never really advertised and can still be used with
- the old release if needed. If there is interest
- it could be revived into its own tool i guess.
-
-* fix issue48 and issue59: raise an Error if the module
- from an imported test file does not seem to come from
- the filepath - avoids "same-name" confusion that has
- been reported repeatedly
-

- nose-style setup_module() and setup() functions are
- supported
-
-* introduce generalized py.test.mark function marking
-
-* reshuffle / refine command line grouping
-
-* deprecate parser.addgroup in favour of getgroup which creates option group
-
-* add --report command line option that allows to control showing of skipped/xfailed sections

-* generalized skipping: a new way to mark python functions with skipif or xfail
- at function, class and modules level based on platform or sys-module attributes.
-
-* extend py.test.mark decorator to allow for positional args
-
-* introduce and test "py.cleanup -d" to remove empty directories
-
-* fix issue #59 - robustify unittest test collection

-
-* merge Jarko's fixes, issue #45 and #46
-
-* add the ability to specify a path for py.lookup to search in
-
-* fix a funcarg cached_setup bug probably only occuring

-
-* many fixes and changes for making the code base python3 compatible,
- many thanks to Benjamin Peterson for helping with this.
-
-* consolidate builtins implementation to be compatible with >=2.3,
- add helpers to ease keeping 2 and 3k compatible code
-
-* deprecate py.compat.doctest|subprocess|textwrap|optparse
-
-* deprecate py.magic.autopath, remove py/magic directory
-

- in favour of (less) py.code ones.
-
-* consolidate and cleanup py/code classes and files
-
-* cleanup py/misc, move tests to bin-for-dist
-
-* introduce delattr/delitem/delenv methods to py.test's monkeypatch funcarg
-
-* consolidate py.log implementation, remove old approach.
-
-* introduce py.io.TextIO and py.io.BytesIO for distinguishing between
- text/unicode and byte-streams (uses underlying standard lib io.*
- if available)
-
-* make py.unittest_convert helper script available which converts "unittest.py"
- style files into the simpler assert/direct-test-classes py.test/nosetests
- style. The script was written by Laura Creighton.
-
-* simplified internal localpath implementation
-
-1.0.2
-=====
-
-* fixing packaging issues, triggered by fedora redhat packaging,
- also added doc, examples and contrib dirs to the tarball.
-
-* added a documentation link to the new django plugin.
-
-1.0.1
-=====
-
-* added a 'pytest_nose' plugin which handles nose.SkipTest,
- nose-style function/method/generator setup/teardown and
- tries to report functions correctly.
-
-* capturing of unicode writes or encoded strings to sys.stdout/err
- work better, also terminalwriting was adapted and somewhat
- unified between windows and linux.
-
-* improved documentation layout and content a lot
-
-* added a "--help-config" option to show conftest.py / ENV-var names for
- all longopt cmdline options, and some special conftest.py variables.
- renamed 'conf_capture' conftest setting to 'option_capture' accordingly.
-
-* fix issue #27: better reporting on non-collectable items given on commandline
- (e.g. pyc files)
-
-* fix issue #33: added --version flag (thanks Benjamin Peterson)
-
-* fix issue #32: adding support for "incomplete" paths to wcpath.status()
-
-* "Test" prefixed classes are *not* collected by default anymore if they
- have an __init__ method
-
-* monkeypatch setenv() now accepts a "prepend" parameter
-
-* improved reporting of collection error tracebacks
-
-* simplified multicall mechanism and plugin architecture,
- renamed some internal methods and argnames
-
-1.0.0
-=====
-
-* more terse reporting try to show filesystem path relatively to current dir
-* improve xfail output a bit
-
-1.0.0b9
-=======
-
-* cleanly handle and report final teardown of test setup
-
-* fix svn-1.6 compat issue with py.path.svnwc().versioned()
- (thanks Wouter Vanden Hove)
-
-* setup/teardown or collection problems now show as ERRORs
- or with big "E"'s in the progress lines. they are reported
- and counted separately.
-
-* dist-testing: properly handle test items that get locally
- collected but cannot be collected on the remote side - often
- due to platform/dependency reasons
-
-* simplified py.test.mark API - see keyword plugin documentation
-
-* integrate better with logging: capturing now by default captures
- test functions and their immediate setup/teardown in a single stream
-
-* capsys and capfd funcargs now have a readouterr() and a close() method
- (underlyingly py.io.StdCapture/FD objects are used which grew a
- readouterr() method as well to return snapshots of captured out/err)
-
-* make assert-reinterpretation work better with comparisons not
- returning bools (reported with numpy from thanks maciej fijalkowski)
-
-* reworked per-test output capturing into the pytest_iocapture.py plugin
- and thus removed capturing code from config object
-
-* item.repr_failure(excinfo) instead of item.repr_failure(excinfo, outerr)
-
-
-1.0.0b8
-=======
-
-* pytest_unittest-plugin is now enabled by default
-
-* introduced pytest_keyboardinterrupt hook and
- refined pytest_sessionfinish hooked, added tests.
-
-* workaround a buggy logging module interaction ("closing already closed
- files"). Thanks to Sridhar Ratnakumar for triggering.
-
-* if plugins use "py.test.importorskip" for importing
- a dependency only a warning will be issued instead
- of exiting the testing process.
-
-* many improvements to docs:
- - refined funcargs doc , use the term "factory" instead of "provider"
- - added a new talk/tutorial doc page
- - better download page
- - better plugin docstrings
- - added new plugins page and automatic doc generation script
-
-* fixed teardown problem related to partially failing funcarg setups
- (thanks MrTopf for reporting), "pytest_runtest_teardown" is now
- always invoked even if the "pytest_runtest_setup" failed.
-
-* tweaked doctest output for docstrings in py modules,
- thanks Radomir.
-
-1.0.0b7
-=======
-
-* renamed py.test.xfail back to py.test.mark.xfail to avoid
- two ways to decorate for xfail
-
-* re-added py.test.mark decorator for setting keywords on functions
- (it was actually documented so removing it was not nice)
-
-* remove scope-argument from request.addfinalizer() because
- request.cached_setup has the scope arg. TOOWTDI.
-
-* perform setup finalization before reporting failures
-
-* apply modified patches from Andreas Kloeckner to allow
- test functions to have no func_code (#22) and to make
- "-k" and function keywords work (#20)
-
-* apply patch from Daniel Peolzleithner (issue #23)
-
-* resolve issue #18, multiprocessing.Manager() and
- redirection clash
-

- files.
-
-* added new pytest_namespace(config) hook that allows
- to inject helpers directly to the py.test.* namespace.
-
-* documented and refined many hooks
-
-* added new style of generative tests via
- pytest_generate_tests hook that integrates
- well with function arguments.
-
-
-1.0.0b1
-=======
-
-* introduced new "funcarg" setup method,
- see doc/test/funcarg.txt
-
-* introduced plugin architecture and many
- new py.test plugins, see
- doc/test/plugins.txt
-
-* teardown_method is now guaranteed to get
- called after a test method has run.

- for his support).
-
-* improved the way of making py.* scripts available in
- windows environments, they are now added to the
- Scripts directory as ".cmd" files.

-Submitting Plugins to pytest-dev
---------------------------------
-
-Pytest development of the core, some plugins and support code happens
-in repositories living under the ``pytest-dev`` organisations:
-
-- `pytest-dev on GitHub <https://github.com/pytest-dev>`_
-
-- `pytest-dev on Bitbucket <https://bitbucket.org/pytest-dev>`_
-
-All pytest-dev Contributors team members have write access to all contained
-repositories. pytest core and plugins are generally developed
-using `pull requests`_ to respective repositories.
-
-The objectives of the ``pytest-dev`` organisation are:
-
-* Having a central location for popular pytest plugins
-* Sharing some of the maintenance responsibility (in case a maintainer no longer whishes to maintain a plugin)
-
-You can submit your plugin by subscribing to the `pytest-dev mail list
-<https://mail.python.org/mailman/listinfo/pytest-dev>`_ and writing a
-mail pointing to your existing pytest plugin repository which must have
-the following:
-
-- PyPI presence with a ``setup.py`` that contains a license, ``pytest-``
- prefixed name, version number, authors, short and long description.
-
-- a ``tox.ini`` for running tests using `tox <http://tox.testrun.org>`_.
-
-- a ``README.txt`` describing how to use the plugin and on which
- platforms it runs.
-
-- a ``LICENSE.txt`` file or equivalent containing the licensing
- information, with matching info in ``setup.py``.
-
-- an issue tracker for bug reports and enhancement requests.
-
-If no contributor strongly objects and two agree, the repository can then be
-transferred to the ``pytest-dev`` organisation.
-
-Here's a rundown of how a repository transfer usually proceeds
-(using a repository named ``joedoe/pytest-xyz`` as example):
-
-* One of the ``pytest-dev`` administrators creates:
-
- - ``pytest-xyz-admin`` team, with full administration rights to
- ``pytest-dev/pytest-xyz``.
- - ``pytest-xyz-developers`` team, with write access to
- ``pytest-dev/pytest-xyz``.
-
-* ``joedoe`` is invited to the ``pytest-xyz-admin`` team;
-
-* After accepting the invitation, ``joedoe`` transfers the repository from its
- original location to ``pytest-dev/pytest-xyz`` (A nice feature is that GitHub handles URL redirection from
- the old to the new location automatically).
-
-* ``joedoe`` is free to add any other collaborators to the
- ``pytest-xyz-admin`` or ``pytest-xyz-developers`` team as desired.
-
-The ``pytest-dev/Contributors`` team has write access to all projects, and
-every project administrator is in it. We recommend that each plugin has at least three
-people who have the right to release to PyPI.
-
-Repository owners can be assured that no ``pytest-dev`` administrator will ever make
-releases of your repository or take ownership in any way, except in rare cases
-where someone becomes unresponsive after months of contact attempts.
-As stated, the objective is to share maintenance and avoid "plugin-abandon".

-Preparing Pull Requests on GitHub
----------------------------------
-
-There's an excellent tutorial on how Pull Requests work in the
-`GitHub Help Center <https://help.github.com/articles/using-pull-requests/>`_
-
-
-.. note::
- What is a "pull request"? It informs project's core developers about the
- changes you want to review and merge. Pull requests are stored on
- `GitHub servers <https://github.com/pytest-dev/pytest/pulls>`_.
- Once you send pull request, we can discuss it's potential modifications and
- even add more commits to it later on.
-
-There's an excellent tutorial on how Pull Requests work in the
-`GitHub Help Center <https://help.github.com/articles/using-pull-requests/>`_,
-but here is a simple overview:
-
-#. Fork the
- `pytest GitHub repository <https://github.com/pytest-dev/pytest>`__. It's
- fine to use ``pytest`` as your fork repository name because it will live
- under your user.
-
-#. Clone your fork locally using `git <https://git-scm.com/>`_ and create a branch::
-
- $ git clone git@github.com:YOUR_GITHUB_USERNAME/pytest.git
- $ cd pytest
- # now, to fix a bug create your own branch off "master":
-
- $ git checkout -b your-bugfix-branch-name master
-
- # or to instead add a feature create your own branch off "features":
-
- $ git checkout -b your-feature-branch-name features
-
- Given we have "major.minor.micro" version numbers, bugfixes will usually
- be released in micro releases whereas features will be released in
- minor releases and incompatible changes in major releases.
-
- If you need some help with Git, follow this quick start
- guide: https://git.wiki.kernel.org/index.php/QuickStart
-
-#. Install tox
-
- Tox is used to run all the tests and will automatically setup virtualenvs
- to run the tests in.
- (will implicitly use http://www.virtualenv.org/en/latest/)::
-
- $ pip install tox
-
-#. Run all the tests
-
- You need to have Python 2.7 and 3.5 available in your system. Now
- running tests is as simple as issuing this command::
-
- $ python runtox.py -e linting,py27,py35
-
- This command will run tests via the "tox" tool against Python 2.7 and 3.5
- and also perform "lint" coding-style checks. ``runtox.py`` is
- a thin wrapper around ``tox`` which installs from a development package
- index where newer (not yet released to pypi) versions of dependencies
- (especially ``py``) might be present.
-
-#. You can now edit your local working copy.
-
- You can now make the changes you want and run the tests again as necessary.
-
- To run tests on py27 and pass options to pytest (e.g. enter pdb on failure)
- to pytest you can do::
-
- $ python runtox.py -e py27 -- --pdb
-
- or to only run tests in a particular test module on py35::
-
- $ python runtox.py -e py35 -- testing/test_config.py
-
-#. Commit and push once your tests pass and you are happy with your change(s)::
-
- $ git commit -a -m "<commit message>"
- $ git push -u
-
- Make sure you add a CHANGELOG message, and add yourself to AUTHORS. If you
- are unsure about either of these steps, submit your pull request and we'll
- help you fix it up.
-
-#. Finally, submit a pull request through the GitHub website using this data::
-
- head-fork: YOUR_GITHUB_USERNAME/pytest
- compare: your-branch-name
-
- base-fork: pytest-dev/pytest
- base: master # if it's a bugfix
- base: feature # if it's a feature

-How to release pytest
---------------------------------------------
-
-Note: this assumes you have already registered on pypi.
-
-0. create the branch release-VERSION
- use features as base for minor/major releases
- and master as base for bugfix releases
-
-1. Bump version numbers in _pytest/__init__.py (setup.py reads it)
-
-2. Check and finalize CHANGELOG
-
-3. Write doc/en/announce/release-VERSION.txt and include
- it in doc/en/announce/index.txt::
-
- git log 2.8.2..HEAD --format='%aN' | sort -u # lists the names of authors involved
-
-4. Use devpi for uploading a release tarball to a staging area::
-
- devpi use https://devpi.net/USER/dev
- devpi upload --formats sdist,bdist_wheel
-
-5. Run from multiple machines::
-
- devpi use https://devpi.net/USER/dev
- devpi test pytest==VERSION
-
-6. Check that tests pass for relevant combinations with::
-
- devpi list pytest
-
- or look at failures with "devpi list -f pytest".
-
-7. Regenerate the docs examples using tox, and check for regressions::
-
- tox -e regen
- git diff
-
-
-8. Build the docs, you need a virtualenv with py and sphinx
- installed::
-
- cd doc/en
- make html
-
- Commit any changes before tagging the release.
-
-9. Tag the release::
-
- git tag VERSION
- git push
-
-10. Upload the docs using doc/en/Makefile::
-
- cd doc/en
- make install # or "installall" if you have LaTeX installed for PDF
-
- This requires ssh-login permission on pytest.org because it uses
- rsync.
- Note that the ``install`` target of ``doc/en/Makefile`` defines where the
- rsync goes to, typically to the "latest" section of pytest.org.
-
- If you are making a minor release (e.g. 5.4), you also need to manually
- create a symlink for "latest"::
-
- ssh pytest-dev@pytest.org
- ln -s 5.4 latest
-
- Browse to pytest.org to verify.
-
-11. Publish to pypi::
-
- devpi push pytest-VERSION pypi:NAME
-
- where NAME is the name of pypi.python.org as configured in your ``~/.pypirc``
- file `for devpi <http://doc.devpi.net/latest/quickstart-releaseprocess.html?highlight=pypirc#devpi-push-releasing-to-an-external-index>`_.
-
-
-12. Send release announcement to mailing lists:
-
- - pytest-dev
- - testing-in-python
- - python-announce-list@python.org
-
-
-13. **after the release** Bump the version number in ``_pytest/__init__.py``,
- to the next Minor release version (i.e. if you released ``pytest-2.8.0``,
- set it to ``pytest-2.9.0.dev1``).
-
-14. merge the actual release into the master branch and do a pull request against it
-15. merge from master to features

-recorder = monkeypatch.function(".......")
--------------------------------------------------------------
-tags: nice feature
-
-Like monkeypatch.replace but sets a mock-like call recorder:
-
- recorder = monkeypatch.function("os.path.abspath")
- recorder.set_return("/hello")
- os.path.abspath("hello")
- call, = recorder.calls
- assert call.args.path == "hello"
- assert call.returned == "/hello"
- ...
-
-Unlike mock, "args.path" acts on the parsed auto-spec'ed ``os.path.abspath``
-so it's independent from if the client side called "os.path.abspath(path=...)"
-or "os.path.abspath('positional')".
-
-
-refine parametrize API
--------------------------------------------------------------
-tags: critical feature
-
-extend metafunc.parametrize to directly support indirection, example:
-
- def setupdb(request, config):
- # setup "resource" based on test request and the values passed
- # in to parametrize. setupfunc is called for each such value.
- # you may use request.addfinalizer() or request.cached_setup ...
- return dynamic_setup_database(val)
-
- @pytest.mark.parametrize("db", ["pg", "mysql"], setupfunc=setupdb)
- def test_heavy_functional_test(db):
- ...
-
-There would be no need to write or explain funcarg factories and
-their special __ syntax.
-
-The examples and improvements should also show how to put the parametrize
-decorator to a class, to a module or even to a directory. For the directory
-part a conftest.py content like this::
-
- pytestmark = [
- @pytest.mark.parametrize_setup("db", ...),
- ]
-
-probably makes sense in order to keep the declarative nature. This mirrors
-the marker-mechanism with respect to a test module but puts it to a directory
-scale.
-
-When doing larger scoped parametrization it probably becomes necessary
-to allow parametrization to be ignored if the according parameter is not
-used (currently any parametrized argument that is not present in a function will cause a ValueError). Example:
-
- @pytest.mark.parametrize("db", ..., mustmatch=False)
-
-means to not raise an error but simply ignore the parametrization
-if the signature of a decorated function does not match. XXX is it
-not sufficient to always allow non-matches?
-
-
-allow parametrized attributes on classes
---------------------------------------------------
-
-tags: wish 2.4
-
-example:
-
- @pytest.mark.parametrize_attr("db", setupfunc, [1,2,3], scope="class")
- @pytest.mark.parametrize_attr("tmp", setupfunc, scope="...")
- class TestMe:
- def test_hello(self):
- access self.db ...
-
-this would run the test_hello() function three times with three
-different values for self.db. This could also work with unittest/nose
-style tests, i.e. it leverages existing test suites without needing
-to rewrite them. Together with the previously mentioned setup_test()
-maybe the setupfunc could be omitted?
-
-optimizations
----------------------------------------------------------------
-tags: 2.4 core
-
-- look at ihook optimization such that all lookups for
- hooks relating to the same fspath are cached.
-
-fix start/finish partial finailization problem
----------------------------------------------------------------
-tags: bug core
-
-if a configure/runtest_setup/sessionstart/... hook invocation partially
-fails the sessionfinishes is not called. Each hook implementation
-should better be repsonsible for registering a cleanup/finalizer
-appropriately to avoid this issue. Moreover/Alternatively, we could
-record which implementations of a hook succeeded and only call their
-teardown.
-
-
-relax requirement to have tests/testing contain an __init__
-----------------------------------------------------------------
-tags: feature
-bb: http://bitbucket.org/hpk42/py-trunk/issue/64
-
-A local test run of a "tests" directory may work
-but a remote one fail because the tests directory
-does not contain an "__init__.py". Either give
-an error or make it work without the __init__.py
-i.e. port the nose-logic of unloading a test module.
-
-customize test function collection
--------------------------------------------------------
-tags: feature
-
-- introduce pytest.mark.nocollect for not considering a function for
- test collection at all. maybe also introduce a pytest.mark.test to
- explicitly mark a function to become a tested one. Lookup JUnit ways
- of tagging tests.
-
-introduce pytest.mark.importorskip
--------------------------------------------------------
-tags: feature
-
-in addition to the imperative pytest.importorskip also introduce
-a pytest.mark.importorskip so that the test count is more correct.
-
-
-introduce pytest.mark.platform
--------------------------------------------------------
-tags: feature
-
-Introduce nice-to-spell platform-skipping, examples:
-
- @pytest.mark.platform("python3")
- @pytest.mark.platform("not python3")
- @pytest.mark.platform("win32 and not python3")
- @pytest.mark.platform("darwin")
- @pytest.mark.platform("not (jython and win32)")
- @pytest.mark.platform("not (jython and win32)", xfail=True)
-
-etc. Idea is to allow Python expressions which can operate
-on common spellings for operating systems and python
-interpreter versions.
-
-pytest.mark.xfail signature change
--------------------------------------------------------
-tags: feature
-
-change to pytest.mark.xfail(reason, (optional)condition)
-to better implement the word meaning. It also signals
-better that we always have some kind of an implementation
-reason that can be formualated.
-Compatibility? how to introduce a new name/keep compat?
-
-allow to non-intrusively apply skipfs/xfail/marks
----------------------------------------------------
-tags: feature
-
-use case: mark a module or directory structures
-to be skipped on certain platforms (i.e. no import
-attempt will be made).
-
-consider introducing a hook/mechanism that allows to apply marks
-from conftests or plugins. (See extended parametrization)
-
-
-explicit referencing of conftest.py files
------------------------------------------
-tags: feature
-
-allow to name conftest.py files (in sub directories) that should
-be imported early, as to include command line options.
-
-improve central pytest ini file
--------------------------------
-tags: feature
-
-introduce more declarative configuration options:
-- (to-be-collected test directories)
-- required plugins
-- test func/class/file matching patterns
-- skip/xfail (non-intrusive)
-- pytest.ini and tox.ini and setup.cfg configuration in the same file
-
-new documentation
-----------------------------------
-tags: feature
-
-- logo pytest
-- examples for unittest or functional testing
-- resource management for functional testing
-- patterns: page object
-
-have imported module mismatch honour relative paths
---------------------------------------------------------
-tags: bug
-
-With 1.1.1 pytest fails at least on windows if an import
-is relative and compared against an absolute conftest.py
-path. Normalize.
-
-consider globals: pytest.ensuretemp and config
---------------------------------------------------------------
-tags: experimental-wish
-
-consider deprecating pytest.ensuretemp and pytest.config
-to further reduce pytest globality. Also consider
-having pytest.config and ensuretemp coming from
-a plugin rather than being there from the start.
-
-
-consider pytest_addsyspath hook
------------------------------------------
-tags: wish
-
-pytest could call a new pytest_addsyspath() in order to systematically
-allow manipulation of sys.path and to inhibit it via --no-addsyspath
-in order to more easily run against installed packages.
-
-Alternatively it could also be done via the config object
-and pytest_configure.
-
-
-
-deprecate global pytest.config usage
-----------------------------------------------------------------
-tags: feature
-
-pytest.ensuretemp and pytest.config are probably the last
-objects containing global state. Often using them is not
-necessary. This is about trying to get rid of them, i.e.
-deprecating them and checking with PyPy's usages as well
-as others.
-
-remove deprecated bits in collect.py
--------------------------------------------------------------------
-tags: feature
-
-In an effort to further simplify code, review and remove deprecated bits
-in collect.py. Probably good:
-- inline consider_file/dir methods, no need to have them
- subclass-overridable because of hooks
-
-implement fslayout decorator
----------------------------------
-tags: feature
-
-Improve the way how tests can work with pre-made examples,
-keeping the layout close to the test function:
-
-@pytest.mark.fslayout("""
- conftest.py:
- # empty
- tests/
- test_%(NAME)s: # becomes test_run1.py
- def test_function(self):
- pass
-""")
-def test_run(pytester, fslayout):
- p = fslayout.findone("test_*.py")
- result = pytester.runpytest(p)
- assert result.ret == 0
- assert result.passed == 1
-
-Another idea is to allow to define a full scenario including the run
-in one content string::
-
- runscenario("""
- test_{TESTNAME}.py:
- import pytest
- @pytest.mark.xfail
- def test_that_fails():
- assert 0
-
- @pytest.mark.skipif("True")
- def test_hello():
- pass
-
- conftest.py:
- import pytest
- def pytest_runsetup_setup(item):
- pytest.skip("abc")
-
- runpytest -rsxX
- *SKIP*{TESTNAME}*
- *1 skipped*
- """)
-
-This could be run with at least three different ways to invoke pytest:
-through the shell, through "python -m pytest" and inlined. As inlined
-would be the fastest it could be run first (or "--fast" mode).
-
-
-Create isolate plugin
----------------------
-tags: feature
-
-The idea is that you can e.g. import modules in a test and afterwards
-sys.modules, sys.meta_path etc would be reverted. It can go further
-then just importing however, e.g. current working directory, file
-descriptors, ...
-
-This would probably be done by marking::
-
- @pytest.mark.isolate(importing=True, cwd=True, fds=False)
- def test_foo():
- ...
-
-With the possibility of doing this globally in an ini-file.
-
-
-fnmatch for test names
-----------------------
-tags: feature-wish
-
-various testsuites use suffixes instead of prefixes for test classes
-also it lends itself to bdd style test names::
-
- class UserBehaviour:
- def anonymous_should_not_have_inbox(user):
- ...
- def registred_should_have_inbox(user):
- ..
-
-using the following in pytest.ini::
-
- [pytest]
- python_classes = Test *Behaviour *Test
- python_functions = test *_should_*
-
-
-mechanism for running named parts of tests with different reporting behaviour
-------------------------------------------------------------------------------
-tags: feature-wish-incomplete
-
-a few use-cases come to mind:
-
-* fail assertions and record that without stopping a complete test
-
- * this is in particular hepfull if a small bit of a test is known to fail/xfail::
-
- def test_fun():
- with pytest.section('fdcheck, marks=pytest.mark.xfail_if(...)):
- breaks_on_windows()
-
-* divide functional/acceptance tests into sections
-* provide a different mechanism for generators, maybe something like::
-
- def pytest_runtest_call(item)
- if not generator:
- ...
- prepare_check = GeneratorCheckprepare()
-
- gen = item.obj(**fixtures)
- for check in gen
- id, call = prepare_check(check)
- # bubble should only prevent exception propagation after a failure
- # the whole test should still fail
- # there might be need for a lower level api and taking custom markers into account
- with pytest.section(id, bubble=False):
- call()

-The ``pytest`` framework makes it easy to write small tests, yet
-scales to support complex functional testing for applications and libraries.
-
-An example of a simple test:
-
-.. code-block:: python
-
- # content of test_sample.py
- def func(x):
- return x + 1
-
- def test_answer():
- assert func(3) == 5
-
-
-To execute it::
-
- $ py.test
- ======= test session starts ========
- platform linux -- Python 3.4.3, pytest-2.8.5, py-1.4.31, pluggy-0.3.1
- collected 1 items
-
- test_sample.py F
-
- ======= FAILURES ========
- _______ test_answer ________
-
- def test_answer():
- > assert func(3) == 5
- E assert 4 == 5
- E + where 4 = func(3)
-
- test_sample.py:5: AssertionError
- ======= 1 failed in 0.12 seconds ========
-
-Due to ``py.test``'s detailed assertion introspection, only plain ``assert`` statements are used. See `getting-started <http://pytest.org/latest/getting-started.html#our-first-test-run>`_ for more examples.

-"""allow bash-completion for argparse with argcomplete if installed
-needs argcomplete>=0.5.6 for python 3.2/3.3 (older versions fail
-to find the magic string, so _ARGCOMPLETE env. var is never set, and
-this does not need special code.
-
-argcomplete does not support python 2.5 (although the changes for that
-are minor).
-
-Function try_argcomplete(parser) should be called directly before
-the call to ArgumentParser.parse_args().
-
-The filescompleter is what you normally would use on the positional
-arguments specification, in order to get "dirname/" after "dirn<TAB>"
-instead of the default "dirname ":
-
- optparser.add_argument(Config._file_or_dir, nargs='*'
- ).completer=filescompleter
-
-Other, application specific, completers should go in the file
-doing the add_argument calls as they need to be specified as .completer
-attributes as well. (If argcomplete is not installed, the function the
-attribute points to will not be used).
-
-SPEEDUP
-=======
-The generic argcomplete script for bash-completion
-(/etc/bash_completion.d/python-argcomplete.sh )
-uses a python program to determine startup script generated by pip.
-You can speed up completion somewhat by changing this script to include
- # PYTHON_ARGCOMPLETE_OK
-so the the python-argcomplete-check-easy-install-script does not
-need to be called to find the entry point of the code and see if that is
-marked with PYTHON_ARGCOMPLETE_OK
-
-INSTALL/DEBUGGING
-=================
-To include this support in another application that has setup.py generated
-scripts:
-- add the line:
- # PYTHON_ARGCOMPLETE_OK
- near the top of the main python entry point
-- include in the file calling parse_args():
- from _argcomplete import try_argcomplete, filescompleter
- , call try_argcomplete just before parse_args(), and optionally add
- filescompleter to the positional arguments' add_argument()
-If things do not work right away:
-- switch on argcomplete debugging with (also helpful when doing custom
- completers):
- export _ARC_DEBUG=1
-- run:
- python-argcomplete-check-easy-install-script $(which appname)
- echo $?
- will echo 0 if the magic line has been found, 1 if not
-- sometimes it helps to find early on errors using:
- _ARGCOMPLETE=1 _ARC_DEBUG=1 appname
- which should throw a KeyError: 'COMPLINE' (which is properly set by the
- global argcomplete script).

- finds call .visit() with it. Then .visit_Assert() takes over and
- is responsible for creating new ast statements to replace the

- to provide intermediate values and replace it with an if statement
- which raises an assertion error with a detailed explanation in
- case the expression is false.
-
- For this .visit_Assert() uses the visitor pattern to visit all the
- AST nodes of the ast.Assert.test field, each visit call returning
- an AST node and the corresponding explanation string. During this
- state is kept in several instance attributes:
-
- :statements: All the AST statements which will replace the assert
- statement.
-
- :variables: This is populated by .variable() with each variable
- used by the statements so that they can all be set to None at
- the end of the statements.
-
- :variable_counter: Counter to create new unique variables needed
- by statements. Variables are created using .variable() and
- have the form of "@py_assert0".
-
- :on_failure: The AST statements which will be executed if the
- assertion test fails. This is the code which will construct
- the failure message and raises the AssertionError.
-
- :explanation_specifiers: A dict filled by .explanation_param()
- with %-formatting placeholders and their corresponding
- expressions to use in the building of an assertion message.
- This is used by .pop_format_context() to build a message.
-
- :stack: A stack of the explanation_specifiers dicts maintained by
- .push_format_context() and .pop_format_context() which allows
- to build another %-formatted string while already building one.
