+dpub-aam: Tests for the DPUB-ARIA Accessibility Mapping Recommendation
+======================================================================
+
+The [DPUB ARIA Recommendation](https://www.w3.org/TR/dpub-aam-1.0)
+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 Recommendation.
+
+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.
+2. Start up the test driver window and select the dpub-aam tests to be run
+   (e.g., the DPUB AAM 1.0 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.
+
+
+Writing Tests
+-------------
+
+If you are interested in writing tests for this environment, see the
+associated [CONTRIBUTING](CONTRIBUTING.md) document.

-     * Each test is run twice: once using etag/If-None-Match and once with
-     * date/If-Modified-Since.  Each test run gets its own URL and randomized
-     * content and operates independently.
-     *
-     * The test steps are run with request_cache.length fetch requests issued
-     * and their immediate results sanity-checked.  The cache.py server script
-     * stashes an entry containing any If-None-Match, If-Modified-Since, Pragma,
-     * and Cache-Control observed headers for each request it receives.  When
-     * the test fetches have run, this state is retrieved from cache.py and the
-     * expected_* lists are checked, including their length.
-     *
-     * This means that if a request_* fetch is expected to hit the cache and not
-     * touch the network, then there will be no entry for it in the expect_*
-     * lists.  AKA (request_cache.length - expected_validation_headers.length)
-     * should equal the number of cache hits that didn't touch the network.
-     *
-     * Test dictionary keys:
-     * - state: required string that determines whether the Expires response for
-     *   the fetched document should be set in the future ("fresh") or past
-     *   ("stale").
-     * - vary: optional string to be passed to the server for it to quote back
-     *   in a Vary header on the response to us.
-     * - cache_control: optional string to be passed to the server for it to
-     *   quote back in a Cache-Control header on the response to us.
-     * - redirect: optional string "same-origin" or "cross-origin".  If
-     *   provided, the server will issue an absolute redirect to the script on
-     *   the same or a different origin, as appropriate.  The redirected
-     *   location is the script with the redirect parameter removed, so the
-     *   content/state/etc. will be as if you hadn't specified a redirect.
-     * - request_cache: required array of cache modes to use (via `cache`).
-     * - request_headers: optional array of explicit fetch `headers` arguments.
-     *   If provided, the server will log an empty dictionary for each request
-     *   instead of the request headers it would normally log.
-     * - response: optional array of specialized response handling.  Right now,
-     *   "error" array entries indicate a network error response is expected
-     *   which will reject with a TypeError.
-     * - expected_validation_headers: required boolean array indicating whether
-     *   the server should have seen an If-None-Match/If-Modified-Since header
-     *   in the request.
-     * - expected_no_cache_headers: required boolean array indicating whether
-     *   the server should have seen Pragma/Cache-control:no-cache headers in
-     *   the request.
-     * - expected_max_age_headers: optional boolean array indicating whether
-     *   the server should have seen a Cache-Control:max-age=0 header in the
-     *   request.

+/**
+ * Each test is run twice: once using etag/If-None-Match and once with
+ * date/If-Modified-Since.  Each test run gets its own URL and randomized
+ * content and operates independently.
+ *
+ * The test steps are run with request_cache.length fetch requests issued
+ * and their immediate results sanity-checked.  The cache.py server script
+ * stashes an entry containing any If-None-Match, If-Modified-Since, Pragma,
+ * and Cache-Control observed headers for each request it receives.  When
+ * the test fetches have run, this state is retrieved from cache.py and the
+ * expected_* lists are checked, including their length.
+ *
+ * This means that if a request_* fetch is expected to hit the cache and not
+ * touch the network, then there will be no entry for it in the expect_*
+ * lists.  AKA (request_cache.length - expected_validation_headers.length)
+ * should equal the number of cache hits that didn't touch the network.
+ *
+ * Test dictionary keys:
+ * - state: required string that determines whether the Expires response for
+ *   the fetched document should be set in the future ("fresh") or past
+ *   ("stale").
+ * - vary: optional string to be passed to the server for it to quote back
+ *   in a Vary header on the response to us.
+ * - cache_control: optional string to be passed to the server for it to
+ *   quote back in a Cache-Control header on the response to us.
+ * - redirect: optional string "same-origin" or "cross-origin".  If
+ *   provided, the server will issue an absolute redirect to the script on
+ *   the same or a different origin, as appropriate.  The redirected
+ *   location is the script with the redirect parameter removed, so the
+ *   content/state/etc. will be as if you hadn't specified a redirect.
+ * - request_cache: required array of cache modes to use (via `cache`).
+ * - request_headers: optional array of explicit fetch `headers` arguments.
+ *   If provided, the server will log an empty dictionary for each request
+ *   instead of the request headers it would normally log.
+ * - response: optional array of specialized response handling.  Right now,
+ *   "error" array entries indicate a network error response is expected
+ *   which will reject with a TypeError.
+ * - expected_validation_headers: required boolean array indicating whether
+ *   the server should have seen an If-None-Match/If-Modified-Since header
+ *   in the request.
+ * - expected_no_cache_headers: required boolean array indicating whether
+ *   the server should have seen Pragma/Cache-control:no-cache headers in
+ *   the request.
+ * - expected_max_age_headers: optional boolean array indicating whether
+ *   the server should have seen a Cache-Control:max-age=0 header in the
+ *   request.

+# MathML: Tests for the MathML in HTML5 implementation note
+
+This directory contains tests for the
+[MathML in HTML5 implementation note](http://www.mathml-association.org/MathMLinHTML5/)
+which is itself based on the
+[HTML5 W3C recommendation](https://www.w3.org/TR/html5/),
+on the [MathML3 W3C recommendation](https://www.w3.org/TR/MathML3/)
+and on the
+[Open Font Format 3](http://www.iso.org/iso/home/store/catalogue_ics/catalogue_detail_ics.htm?csnumber=66391) standard.
+
+Many of the tests verify OpenType features and require specific Web fonts for
+that purpose. WOFF fonts are generated by scripts in the `tools/` folder using
+the Python API of
+[fontforge](https://github.com/fontforge/fontforge/). A recent enough version
+of FontForge is necessary so that it includes fixes for
+[WOFF checkSumAdjustment](https://github.com/fontforge/fontforge/issues/926),
+[USE_TYPO_METRICS flag](https://github.com/fontforge/fontforge/pull/2274) and
+for other various bugs.

+2. License Grants and Conditions
+--------------------------------
+
+2.1. Grants
+
+Each Contributor hereby grants You a world-wide, royalty-free,
+non-exclusive license:
+
+(a) under intellectual property rights (other than patent or trademark)
+    Licensable by such Contributor to use, reproduce, make available,
+    modify, display, perform, distribute, and otherwise exploit its
+    Contributions, either on an unmodified basis, with Modifications, or
+    as part of a Larger Work; and
+
+(b) under Patent Claims of such Contributor to make, use, sell, offer
+    for sale, have made, import, and otherwise transfer either its
+    Contributions or its Contributor Version.
+
+2.2. Effective Date
+
+The licenses granted in Section 2.1 with respect to any Contribution
+become effective for each Contribution on the date the Contributor first
+distributes such Contribution.
+
+2.3. Limitations on Grant Scope
+
+The licenses granted in this Section 2 are the only rights granted under
+this License. No additional rights or licenses will be implied from the
+distribution or licensing of Covered Software under this License.
+Notwithstanding Section 2.1(b) above, no patent license is granted by a
+Contributor:
+
+(a) for any code that a Contributor has removed from Covered Software;
+    or
+
+(b) for infringements caused by: (i) Your and any other third party's
+    modifications of Covered Software, or (ii) the combination of its
+    Contributions with other software (except as part of its Contributor
+    Version); or
+
+(c) under Patent Claims infringed by Covered Software in the absence of
+    its Contributions.
+
+This License does not grant any rights in the trademarks, service marks,
+or logos of any Contributor (except as may be necessary to comply with
+the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+No Contributor makes additional grants as a result of Your choice to
+distribute the Covered Software under a subsequent version of this
+License (see Section 10.2) or under the terms of a Secondary License (if
+permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+Each Contributor represents that the Contributor believes its
+Contributions are its original creation(s) or it has sufficient rights
+to grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+This License is not intended to limit any rights You have under
+applicable copyright doctrines of fair use, fair dealing, or other
+equivalents.
+
+2.7. Conditions
+
+Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
+in Section 2.1.
+
+3. Responsibilities
+-------------------
+
+3.1. Distribution of Source Form
+
+All distribution of Covered Software in Source Code Form, including any
+Modifications that You create or to which You contribute, must be under
+the terms of this License. You must inform recipients that the Source
+Code Form of the Covered Software is governed by the terms of this
+License, and how they can obtain a copy of this License. You may not
+attempt to alter or restrict the recipients' rights in the Source Code
+Form.
+
+3.2. Distribution of Executable Form
+
+If You distribute Covered Software in Executable Form then:
+
+(a) such Covered Software must also be made available in Source Code
+    Form, as described in Section 3.1, and You must inform recipients of
+    the Executable Form how they can obtain a copy of such Source Code
+    Form by reasonable means in a timely manner, at a charge no more
+    than the cost of distribution to the recipient; and
+
+(b) You may distribute such Executable Form under the terms of this
+    License, or sublicense it under different terms, provided that the
+    license for the Executable Form does not attempt to limit or alter
+    the recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+You may create and distribute a Larger Work under terms of Your choice,
+provided that You also comply with the requirements of this License for
+the Covered Software. If the Larger Work is a combination of Covered
+Software with a work governed by one or more Secondary Licenses, and the
+Covered Software is not Incompatible With Secondary Licenses, this
+License permits You to additionally distribute such Covered Software
+under the terms of such Secondary License(s), so that the recipient of
+the Larger Work may, at their option, further distribute the Covered
+Software under the terms of either this License or such Secondary
+License(s).
+
+3.4. Notices
+
+You may not remove or alter the substance of any license notices
+(including copyright notices, patent notices, disclaimers of warranty,
+or limitations of liability) contained within the Source Code Form of
+the Covered Software, except that You may alter any license notices to
+the extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+You may choose to offer, and to charge a fee for, warranty, support,
+indemnity or liability obligations to one or more recipients of Covered
+Software. However, You may do so only on Your own behalf, and not on
+behalf of any Contributor. You must make it absolutely clear that any
+such warranty, support, indemnity, or liability obligation is offered by
+You alone, and You hereby agree to indemnify every Contributor for any
+liability incurred by such Contributor as a result of warranty, support,
+indemnity or liability terms You offer. You may include additional
+disclaimers of warranty and limitations of liability specific to any
+jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+---------------------------------------------------
+
+If it is impossible for You to comply with any of the terms of this
+License with respect to some or all of the Covered Software due to
+statute, judicial order, or regulation then You must: (a) comply with
+the terms of this License to the maximum extent possible; and (b)
+describe the limitations and the code they affect. Such description must
+be placed in a text file included with all distributions of the Covered
+Software under this License. Except to the extent prohibited by statute
+or regulation, such description must be sufficiently detailed for a
+recipient of ordinary skill to be able to understand it.
+
+5. Termination
+--------------
+
+5.1. The rights granted under this License will terminate automatically
+if You fail to comply with any of its terms. However, if You become
+compliant, then the rights granted under this License from a particular
+Contributor are reinstated (a) provisionally, unless and until such
+Contributor explicitly and finally terminates Your grants, and (b) on an
+ongoing basis, if such Contributor fails to notify You of the
+non-compliance by some reasonable means prior to 60 days after You have
+come back into compliance. Moreover, Your grants from a particular
+Contributor are reinstated on an ongoing basis if such Contributor
+notifies You of the non-compliance by some reasonable means, this is the
+first time You have received notice of non-compliance with this License
+from such Contributor, and You become compliant prior to 30 days after
+Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+infringement claim (excluding declaratory judgment actions,
+counter-claims, and cross-claims) alleging that a Contributor Version
+directly or indirectly infringes any patent, then the rights granted to
+You by any and all Contributors for the Covered Software under Section
+2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all
+end user license agreements (excluding distributors and resellers) which
+have been validly granted by You or Your distributors under this License
+prior to termination shall survive termination.

+----------------

+unenforceable, such provision shall be reformed only to the extent
+necessary to make it enforceable. Any law or regulation which provides
+that the language of a contract shall be construed against the drafter
+shall not be used to construe this License against a Contributor.

 ## Usage
 
+You can use the built-in
+[context manager](https://docs.python.org/2/reference/compound_stmts.html#the-with-statement)
+to manage the lifetime of the session.
+The session is started implicitly
+at the first call to a command if it has not already been started,
+and will implicitly be ended when exiting the context:
+
+```py
+import webdriver
+
+with webdriver.Session("127.0.0.1", 4444) as session:
+    session.url = "https://mozilla.org"
+    print "The current URL is %s" % session.url
+```
+
+The following is functionally equivalent to the above,
+but giving you manual control of the session:
+
 ```py
 import webdriver
 
-session = webdriver.Session("127.0.0.1", "4444")
+session = webdriver.Session("127.0.0.1", 4444)
 session.start()
 
 session.url = "https://mozilla.org"
