| <h1 id="karma-rules-for-bazel">Karma rules for Bazel</h1> |
| |
| <p>The Karma rules run karma tests with Bazel.</p> |
| |
| <h2 id="installation">Installation</h2> |
| |
| <p>Add the <code>@bazel/karma</code> npm package to your <code>devDependencies</code> in <code>package.json</code>.</p> |
| |
| <p>Now add this to your <code>WORKSPACE</code> to install the Karma dependencies:</p> |
| |
| <figure class="highlight"><pre><code class="language-python" data-lang="python"><span class="c1"># Fetch transitive Bazel dependencies of @bazel/karma |
| </span><span class="n">load</span><span class="p">(</span><span class="s">"@npm//@bazel/karma:package.bzl"</span><span class="p">,</span> <span class="s">"npm_bazel_karma_dependencies"</span><span class="p">)</span> |
| <span class="n">npm_bazel_karma_dependencies</span><span class="p">()</span></code></pre></figure> |
| |
| <p>This installs the <code>io_bazel_rules_webtesting</code> repository, if you haven’t installed it earlier.</p> |
| |
| <p>Finally, configure the rules_webtesting:</p> |
| |
| <figure class="highlight"><pre><code class="language-python" data-lang="python"><span class="c1"># Set up web testing, choose browsers we can test on |
| </span><span class="n">load</span><span class="p">(</span><span class="s">"@io_bazel_rules_webtesting//web:repositories.bzl"</span><span class="p">,</span> <span class="s">"web_test_repositories"</span><span class="p">)</span> |
| |
| <span class="n">web_test_repositories</span><span class="p">()</span> |
| |
| <span class="n">load</span><span class="p">(</span><span class="s">"@io_bazel_rules_webtesting//web/versioned:browsers-0.3.2.bzl"</span><span class="p">,</span> <span class="s">"browser_repositories"</span><span class="p">)</span> |
| |
| <span class="n">browser_repositories</span><span class="p">(</span> |
| <span class="n">chromium</span> <span class="o">=</span> <span class="bp">True</span><span class="p">,</span> |
| <span class="n">firefox</span> <span class="o">=</span> <span class="bp">True</span><span class="p">,</span> |
| <span class="p">)</span></code></pre></figure> |
| |
| <h2 id="installing-with-self-managed-dependencies">Installing with self-managed dependencies</h2> |
| |
| <p>If you didn’t use the <code>yarn_install</code> or <code>npm_install</code> rule to create an <code>npm</code> workspace, you’ll have to declare a rule in your root <code>BUILD.bazel</code> file to execute karma:</p> |
| |
| <figure class="highlight"><pre><code class="language-python" data-lang="python"><span class="c1"># Create a karma rule to use in ts_web_test_suite karma |
| # attribute when using self-managed dependencies |
| </span><span class="n">nodejs_binary</span><span class="p">(</span> |
| <span class="n">name</span> <span class="o">=</span> <span class="s">"karma/karma"</span><span class="p">,</span> |
| <span class="n">entry_point</span> <span class="o">=</span> <span class="s">"//:node_modules/karma/bin/karma"</span><span class="p">,</span> |
| <span class="c1"># Point bazel to your node_modules to find the entry point |
| </span> <span class="n">node_modules</span> <span class="o">=</span> <span class="p">[</span><span class="s">"//:node_modules"</span><span class="p">],</span> |
| <span class="p">)</span></code></pre></figure> |
| |
| <h2 id="karma_web_test">karma_web_test</h2> |
| |
| <p>Runs unit tests in a browser with Karma.</p> |
| |
| <p>When executed under <code>bazel test</code>, this uses a headless browser for speed. |
| This is also because <code>bazel test</code> allows multiple targets to be tested together, |
| and we don’t want to open a Chrome window on your machine for each one. Also, |
| under <code>bazel test</code> the test will execute and immediately terminate.</p> |
| |
| <p>Running under <code>ibazel test</code> gives you a “watch mode” for your tests. The rule is |
| optimized for this case - the test runner server will stay running and just |
| re-serve the up-to-date JavaScript source bundle.</p> |
| |
| <p>To debug a single test target, run it with <code>bazel run</code> instead. This will open a |
| browser window on your computer. Also you can use any other browser by opening |
| the URL printed when the test starts up. The test will remain running until you |
| cancel the <code>bazel run</code> command.</p> |
| |
| <p>This rule will use your system Chrome by default. In the default case, your |
| environment must specify CHROME_BIN so that the rule will know which Chrome binary to run. |
| Other <code>browsers</code> and <code>customLaunchers</code> may be set using the a base Karma configuration |
| specified in the <code>config_file</code> attribute.</p> |
