  37         JavaScript WebAssembly API: baby steps
  38
  39          - Expand WebAssembly constructors into their own files. This requires a lot of
  40            boilerplate, as well as adding the .lut.h files. All of the
  41            JSWebAssembly*.{h,cpp}, as well as Constructor and Prototype files, are
  42            currently the same between the 4 specified WebAssembly constructors. It'll be
  43            easy to implement individual functions on constructed objects as per the
  44            spec, and have each of these files diverge. The error constructors are also
  45            similar, except that their instance derives from ErrorInstance.
  46          - Use constructor macro when initializing the global object.
  47          - Dramatically improve testing of the WebAssembly API by checking for
  48            properties specified in the spec [*].
  49          - Clean up assert.js' exception testing.
  50          - Fix a copy-paste bug in wasm.json: floating-point const return values were
  51            swapped.

  53         [*] https://github.com/WebAssembly/design/blob/master/JS.md

 639
 640         These tests auto-generate permutations of values to apply to binary operations.
 641         They also test the operations with 3 permutations of value types:

 644             3. ConstVar - constant / literal operand 1, variable operand 2
 645
 646         We can prevent these tests from timing out by breaking each up to only run 1 of

1451
1452         Reviewed by Saam Barati.
1453
1454         Added Chakra tests.  All these tests are under Chakra/test.  This is the same layout
1455         for tests in the Chakra tree.
1456
1457         Created a ChakraCore.yaml file to be used with run-jsc-stress-tests.  This file contains
1458         the tests that are run when the original Chakra runtests.py script is run.  That script
1459         is the test driver for *nix platforms and does not attempt to run all tests or all
1460         variations of tests.  The runtest.py driver consults rlexe.xml files in each test
1461         subdirectory to determine the test to run, the options to pass to the test and how to
1462         determine pass/fail of the test.  With runtests.py as the start, tests that didn't
1463         pass directly where either skipped, with a message describing why or through
1464         adjustments to the test infrastructure, as described below, where made to pass.
1465
1466         The only modification to the test infrastrucutre are:
1467
1468          1) Added simple mapping of Chakra expected exception text to JSC expected text in
1469             test/UnitTestFramework/UnitTestFramework.js.  It would make sense to also
1470             map some JSC specific exception text to more generic text for the cases where
1471             that text contains indetifier names or other source specific strings and the
1472             Chakra equivolent exception texts are generic.
1473
1474          2) Created JSC specific expected text files where it is clear that the text work
1475             as expected on JSC but the test output is different.  Typically the differences
1476             fall into three categories, different exception output, different output from
1477             toString() of a function, slight numeric differences, and test that rely on
1478             iteration order.
1479
1480          3) Stripped the CR's from the CR-LF line terminations of the files.
1481
1482         No actual test .js files were modified.

1578         The test can fail by design, but this should be fairly rare.
1579
1580         However, when introducing, we wrap the `test()` with 1e4 to ensure the FTL compilation, and this
1581         increases the failure rate. By increasing the MAX in the test, we make the failures much more rare case.
