35         This document is intended to be used as a guideline for the testing
36         activities related to the CSS Shapes Level 1 spec [[!css-shapes-1]]. Its main
37         goal is to provide an overview of the general testing areas, possible
38         caveats and testing aspects not immediately apparent from the spec.
39         Also, it provides a means of tracking the progress of the CSS Shapes
40         spec testing.
41       </p>
42       <p>
43         This document is not meant to replace the spec in determining the
44         normative and non-normative assertions to be tested, but rather
45         complement it.
46       </p>

50       <h2>Goals</h2>
51       <p>
52         To ensure a comprehensive test suite with useful, high quality tests, a
53         number of goals are proposed. They range from process goals (how to
54         conduct testing) to implementation goals (how to write good tests).
55       </p>
56       <section>
57         <h3>Enabling easy test contribution</h3>
58         <p>
59           An important vector in successfully testing CSS Shapes is to
60           enable easy test contributions, both from W3C partners and from
61           non-W3C members that wish to contribute. This is achieved by clearly
62           marking and explaining the areas that need testing, linking to existing
63           tests, and general testing progress.
64         </p>
65       </section>
66       <section>
67         <h3>Providing guidance on testing</h3>
68         <p>
69           In order to increase the quality of the test contributions, this
70           document offers a set of guidelines for conducting testing (see
71           <a href="#approach" class="sectionRef"></a>) and a testing progress
72           tracker to increase the surface coverage of tests (see
73           <a href="#test-progress-tracking" class="sectionRef"></a>).
74         </p>
75       </section>
76       <section>
77         <h3>Creating automation-friendly tests</h3>
78         <p>
79           In terms of actual tests produced for the CSS Shapes specification, the main goal
80           is to ensure that most tests are automatable (i.e. they're either
81           reftests or use <code>testharness.js</code>). Even where manual tests
82           are absolutely necessary they should be written so that they can be
83           easily automated &ndash; as there are ongoing efforts to make
84           WebDriver [[webdriver]] automated tests a first class citizen in W3C
85           testing. This means that even if a manual test requires user
86           interaction, the validation or PASS/FAIL conditions should still be
87           clear enough as to allow automatic validation if said interaction is
88           later automated.

92     <section>
93                 <h2>Approach</h2>
94                 <p>
95                         Since the CSS Shapes Level 1 spec introduces only three new CSS properties,
96                         the approach is to deep dive into every aspect of the spec as much as possible.
97
98                         Tests will be created for the testing areas listed in <a href="#testing-areas" class="sectionRef"></a>.
99                 </p>

101         <section>
102       <h2>Testing areas</h2>
103       <section>
104         <h3>Explicit testing areas</h3>
105         <p>
106           These are testing areas normatively defined by the spec. They cover
107           things explicitly or implicitly defined in the CSS Shapes spec.
108           Please note that while detailed, this list is not necessarily
109           exhaustive and normative behaviors may not be contained in it.
110           When in doubt, consult the CSS Shapes spec or ask a question on the
111           <a href="http://lists.w3.org/Archives/Public/www-style/">mailing
112           list</a>.

116         <h4>Proper parsing of the CSS properties and values according to the spec</h4>
117             <p class=note>
118                 Note: For all of the tests below, where length parameters are tested,
119                       the supported <a class="production css-code" data-link-type=type href=http://www.w3.org/TR/css3-values/#lengths title="<length>">&lt;length&gt;</a>
120                       units defined in the CSS Values &amp; Units [[!CSS3VAL]] specification, but not all permutations will not be
121                       tested. Instead, a sampling of these units will be used across the parsing and layout tests.

388         <h3>Implicit testing areas</h3>
389         <p>
390           These are testing areas either normatively defined in other specs
391           that are explicitly referred to in the CSS Shapes spec. Additionally, the
392           CSS Shapes spec is explicitly referred to by other specs. Please note that
393           while detailed, this list is not necessarily exhaustive and normative behaviors
394           may not be contained in it. When in doubt, consult the CSS Regions spec or ask
395           a question on the <a href="http://lists.w3.org/Archives/Public/www-style/">mailing list</a>.
396         </p>
397         <p>
398           Below is the list of implicit testing areas:

411           <h3>Interactions with other CSS features &amp; specifications</h3>
412           <p>When the CSS Shapes spec has a full suite of tests covering the behaviors defined in the spec,
413              additional tests will be needed to assure that the implementation works properly with other
414              CSS features defined in other specifications.
415           </p>
416           <p>Below is a list of features that should work properly with CSS Shapes:</p>
417           <ul>
418               <li>CSS Transforms</li>
419               <li>CSS Transitions</li>
420               <li>CSS Animations</li>
421               <li>CSS Exclusions</li>
422               <li>CSS Writing Modes - when the float and container have different 'writing-mode' and 'direction' properties</li>
