+Wai-aria: Tests for the WAI-ARIA Recommendations

[tkent, 2016/08/30 02:26:19]

wai-aria/ is a new API directory.  We should skip it.

+================================================
+
+The [WAI ARIA Recommendations](https://www.w3.org/TR/wai-aria)
+define extensions to HTML4/5 for support of extended semantics.  These
+semantics make it easier for Assistive Technologies to intepret and
+present content to users with varying physical and cognitive abilities.
+
+The purpose of these tests is to help ensure that user agents support the
+requirements of the Recommendations.
+
+The general approach for this testing is to enable both manual and automated
+testing, with a preference for automation.
+
+
+Running Tests
+-------------
+
+In order to run these tests in an automated fashion, you will need to have a
+special Assistive Technology Test Adapter (ATTA)  for the platform under test.  We will
+provide a list of these for popular platforms here as they are made available.
+
+The ATTA will monitor the window under test via the platforms Accessibility
+Layer, forwarding information about the Accessibility Tree to the running test
+so that it can evaluate support for the various features under test.
+
+The workflow for running these tests is something like:
+
+1. Start up the ATTA for the platform under test, informing it of the location
+   of the test server and the user agent to be tested.
+2. Start up the test driver window and select the wai-aria tests to be run
+   (e.g., the ARIA 1.1 tests) - click "Start"
+3. A window pops up that shows a test - the description of which tells the
+   tester what is being tested.  In an automated test, the test with proceed
+   without user intervention.  In a manual test, some user input may be required
+   in order to stimulate the test.
+4. The test runs.  Success or failure is determined and reported to the test
+   driver window, which then cycles to the next test in the sequence.
+5. Repeat steps 2-4 until done.
+6. Download the JSON format report of test results, which can then be visually
+   inspected, reported on using various tools, or passed on to W3C for
+   evaluation and collection in the Implementation Report via github.
+
+**Remember that while these tests are written to help exercise implementations,
+their other (important) purpose is to increase confidence that there are
+interoperable implementations.** So, implementers are the audience, but these
+tests are not meant to be a comprehensive collection of tests for a client that
+might implement the Recommendation.
+
+
+Capturing and Reporting Results
+-------------------------------
+
+As tests are run against implementations, if the results of testing are
+submitted to [test-results](https://github.com/w3c/test-results/) then they will
+be automatically included in documents generated by
+[wptreport](https://www.github.com/w3c/wptreport). The same tool can be used
+locally to view reports about recorded results.
