+Chrome Tests
+============
+
+.. _DISCLAIMER:
+
+**DISCLAIMER**
+~~~~~~~~~~~~~~
+
+**NOTE: Please use this document as a reference for existing chrome tests as you do not want to create new chrome tests.
+If you're trying to test privileged browser code, write a browser mochitest instead;
+if you are testing web platform code, use a wpt test, or a "plain" mochitest if you are unable to use a wpt test.**
+
+.. _Introduction:
+
+Introduction
+~~~~~~~~~~~~
+
+A chrome test is similar but not equivalent to a Mochitest running with chrome privileges.
+
+The chrome test suite is an automated testing framework designed to
+allow testing of application chrome windows using JavaScript.
+It allows you to run JavaScript code in the non-electroysis (e10s) content area
+with chrome privileges, instead of directly in the browser window (as browser tests do instead).
+These tests reports results using the same functions as the Mochitest test framework.
+The chrome test suite depends on runtests.py from the Mochitest framework.
+
+.. _Running_the_chrome_tests:
+
+Running the chrome tests
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+To run chrome tests, you need to `build
+Firefox </setup>`__ with your
+changes and find the test or test manifest you want to run.
+
+For example, to run all chrome tests under `toolkit/content`, run the following command:
+
+::
+
+ ./mach test toolkit/content/test/chrome/chrome.ini
+
+To run a single test, just pass the path to the test into mach:
+
+::
+
+ ./mach test toolkit/content/tests/chrome/test_largemenu.html
+
+You can also pass the path to a directory containing many tests. Run
+`./mach test --help` for full documentation.
+
+.. _Writing_chrome_tests:
+
+Writing chrome tests
+~~~~~~~~~~~~~~~~~~~~
+
+A chrome tests is similar but not equivalent to a Mochitest
+running with chrome privileges, i.e. code and UI are referenced by
+``chrome://`` URIs. A basic XHTML test file could look like this:
+
+.. code:: xml
+
+ <?xml version="1.0"?>
+ <?xml-stylesheet href="chrome://global/skin" type="text/css"?>
+ <?xml-stylesheet href="chrome://mochikit/content/tests/SimpleTest/test.css" type="text/css"?>
+
+ <window title="Demo Test"
+ xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">
+ <title>Demo Test</title>
+
+ <script type="application/javascript"
+ src="chrome://mochikit/content/tests/SimpleTest/SimpleTest.js"/>
+
+ <script type="application/javascript">
+ <![CDATA[
+ add_task(async function runTest() {
+ ok (true == 1, "this passes");
+ todo(true === 1, "this fails");
+ });
+ ]]>
+ </script>
+
+ <body xmlns="http://www.w3.org/1999/xhtml">
+ <p id="display"></p>
+ <div id="content" style="display: none"></div>
+ <pre id="test"></pre>
+ </body>
+ </window>
+
+
+The comparison functions are identical to those supported by Mochitests,
+see how the comparison functions work
+in the Mochitest documentation for more details. The `EventUtils helper
+functions <https://searchfox.org/mozilla-central/source/testing/mochitest/tests/SimpleTest/EventUtils.js>`__
+are available on the "EventUtils" object defined in the global scope.
+
+The test suite also supports asynchronous tests.
+To use these asynchronous tests, please use the `add_task() <https://searchfox.org/mozilla-central/source/testing/mochitest/tests/SimpleTest/SimpleTest.js#2025>`__ functionality.
+
+Any exceptions thrown while running a test will be caught and reported
+in the test output as a failure. Exceptions thrown outside of the test's
+context (e.g. in a timeout, event handler, etc) will not be caught, but
+will result in a timed out test.
+
+The test file name must be prefixed with "test_", and must have a file
+extension of ".xhtml". Files that don't match this pattern will be ignored
+by the test harness, but you still can include them. For example, a XUL
+window file opened by your test_demo.xhtml via openDialog should be named
+window_demo.xhtml. Putting the bug number in the file name is recommended
+if your test verifies a bugfix, e.g. "test_bug123456.xhtml".
+
+Helper files can be included, for example, from
+``https://example.com/chrome/dom/workers/test/serviceworkers/serviceworkermanager_iframe.html``.
+
+.. _Adding_a_new_chrome_test_to_the_tree:
+
+Adding a new chrome test to the tree
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+To add a new chrome test to the tree, please use `./mach test addtest the_test_directory/the_test_you_want_to_create.xhtml`.
+For more information about `addtest`, please run `./mach test addtest --help`.
