In the WebExtension API code, most tests are either <a rel="nofollow" class="external text" href="https://translate.google.com/website?sl=pl&tl=iw&hl=en-GB&u=https://firefox-source-docs.mozilla.org/testing/xpcshell/index.html">xpcshell tests</a> or <a rel="nofollow" class="external text" href="https://translate.google.com/website?sl=pl&tl=iw&hl=en-GB&u=https://firefox-source-docs.mozilla.org/testing/mochitest-plain/index.html">(browser-chrome) mochitests</a>. Xpcshell tests are preferred because of the lower overhead. Browser tests need to be written when a test interfaces with browser UI, such as tabs or context menus. Browser tests are not supported on mobile; use mochitests if you need to run tests with a real browser on desktop and mobile.</p> <p>The easiest way to get started with tests is to look at existing tests:</p> <ul> <li>Xpcshell tests: <ul> <li>toolkit/components/extensions/test/xpcshell/ (<a rel="nofollow" class="external text" href="https://translate.google.com/website?sl=pl&tl=iw&hl=en-GB&u=https://searchfox.org/mozilla-central/source/toolkit/components/extensions/test/xpcshell">Searchfox link</a>)</li> <li>browser/components/extensions/test/xpcshell/ (<a rel="nofollow" class="external text" href="https://translate.google.com/website?sl=pl&tl=iw&hl=en-GB&u=https://searchfox.org/mozilla-central/source/browser/components/extensions/test/xpcshell">Searchfox link</a>)</li> <li>mobile/shared/components/extensions/test/xpcshell (<a rel="nofollow" class="external text" href="https://translate.google.com/website?sl=pl&tl=iw&hl=en-GB&u=https://searchfox.org/mozilla-central/source/mobile/shared/components/extensions/test/xpcshell">Searchfox link</a>)</li> </ul></li> </ul> <ul> <li>Browser-chrome tests: <ul> <li>toolkit/components/extensions/test/browser/ (<a rel="nofollow" class="external text" href="https://translate.google.com/website?sl=pl&tl=iw&hl=en-GB&u=https://searchfox.org/mozilla-central/source/toolkit/components/extensions/test/browser">Searchfox link</a>)</li> <li>browser/components/extensions/test/browser/ (<a rel="nofollow" class="external text" href="https://translate.google.com/website?sl=pl&tl=iw&hl=en-GB&u=https://searchfox.org/mozilla-central/source/browser/components/extensions/test/browser">Searchfox link</a>)</li> </ul></li> </ul> <ul> <li>Mochitests: <ul> <li>toolkit/components/extensions/test/mochitest/ (<a rel="nofollow" class="external text" href="https://translate.google.com/website?sl=pl&tl=iw&hl=en-GB&u=https://searchfox.org/mozilla-central/source/toolkit/components/extensions/test/mochitest">Searchfox link</a>)</li> </ul></li> </ul> <ul> <li>Firefox for Android mochitests: <ul> <li>mobile/shared/components/extensions/test/mochitest (<a rel="nofollow" class="external text" href="https://translate.google.com/website?sl=pl&tl=iw&hl=en-GB&u=https://searchfox.org/mozilla-central/source/mobile/shared/components/extensions/test/mochitest">Searchfox link</a>)</li> </ul></li> </ul> <h3><span class="mw-headline" id="Running_tests">Running tests</span></h3> <p>These tests can be run with the <code>mach test</code> command. To run specific test(s), pass the name of the test file or directory to <code>mach test</code>. Sometimes <code>mach test</code> has bugs (e.g. <a rel="nofollow" class="external text" href="https://translate.google.com/website?sl=pl&tl=iw&hl=en-GB&u=https://bugzilla.mozilla.org/show_bug.cgi?id%3D1498636">bug 1498636</a> and <a rel="nofollow" class="external text" href="https://translate.google.com/website?sl=pl&tl=iw&hl=en-GB&u=https://bugzilla.mozilla.org/show_bug.cgi?id%3D1495311">bug 1495311</a>); in that case use <code>mach xpcshell-test</code> or <code>mach mochitest</code> instead of <code>mach test</code> to run the test.</p> <p><code>mach test</code> has minimal output by default. To debug test failures, increase the verbosity of the logs with the <code>--verbose --log-mach-verbose</code> flags. The <code>--sequential</code> flag is not required, but allows for easier debugging because only one test is run at a time (instead of multiple in parallel). Al together, the command to run tests and get maximum debug output is: <code>mach test --verbose --log-mach-verbose --sequential [paths to test files]</code></p> <h3><span class="mw-headline" id="Adding_new_tests">Adding new tests</span></h3> <p>Add your test to an existing file when it is small and fits in that test. Otherwise, create a new test file, and register the test file in one of the .toml files in the same directory as your test, usually browser.toml or xpcshell-common.toml. After creating a new test file, run <code>mach build</code> before running tests. It is not necessary to rebuild if you are changing an existing test file.</p> <p>A test consists of multiple subtasks, which are defined in the test files via add_task(...). Most tests have the following minimal structure:</p> <pre>add_task(async function someShortAndSimpleDescriptionHere() { // Define a test extension. let extension = ExtensionTestUtils.loadExtension( .... ); // Loads the actual extension. await extension.startup(); // Tests here, often using extension.sendMessage and/or extension.awaitMessage // Unload the extension and remove the temporary files. await extension.unload(); }); </pre> <p>ExtensionTestUtils.loadExtension allows you to quickly generate a test extension, and its input parameters are documented at: <a rel="nofollow" class="external free" href="https://translate.google.com/website?sl=pl&tl=iw&hl=en-GB&u=https://searchfox.org/mozilla-central/rev/aecb006bbb135d707ca4b8cea7572dd8abab6817/toolkit/components/extensions/ExtensionTestCommon.sys.mjs%23483-507">https://searchfox.org/mozilla-central/rev/aecb006bbb135d707ca4b8cea7572dd8abab6817/toolkit/components/extensions/ExtensionTestCommon.sys.mjs#483-507</a></p> <p>Another common action in tests is to load a web page or extension page. In xpcshell-tests, use ExtensionTestUtils.loadContentPage.</p> <p>In browser-chrome tests, the BrowserTestUtils namespace provides many useful test helpers, such as BrowserTestUtils.openNewForegroundTab to open a new tab.
