    <p>I have a simple angular / requirejs / node project that loads correctly when viewed from a browser. I'm trying to get e2e tests with karma set up.</p> <p>I've copied all of the e2e configurations and directory structures from <a href="https://github.com/tnajdek/angular-requirejs-seed" rel="nofollow noreferrer" title="the angular-requirejs-seed">the angular-require-js seed</a> into my own project. Unfortunately, the tests in my own project give bizarre (and ever-changing!) results. Here's the stripped-down test I'm trying to run:</p> <pre class="lang-js prettyprint-override"><code>describe('My Application', function() { beforeEach(function() { browser().navigateTo('/'); sleep(0.5); }); it('shows an "Ask a Question" button on the index page', function() { expect(element('a').text()).toBe('Ask a Question'); }); }); </code></pre> <h1>Sometimes the test fails</h1> <p><code>Executed 1 of 1 (1 FAILED) (0.785 secs / 0.614 secs)</code></p> <pre><code>Firefox 22.0 (Mac) My Application shows an "Ask a Question" button on the index page FAILED element 'a' text http://localhost:9876/base/test/lib/angular/angular-scenario.js?1375035800000:25397: Selector a did not match any elements. </code></pre> <p>(but there ARE <code>a</code> elements on the page!)</p> <h1>Sometimes the test hangs</h1> <p><code>Executed 0 of 0</code>! In these cases the test-runner browser does show that it's trying to run a test, but it never completes:</p> <p><img src="https://i.stack.imgur.com/ZGEik.png" alt="It just stays like this forever"></p> <p>It just stays like this forever. My app <em>IS</em> displayed in the browser during this hang.</p> <h1>Without <code>element('a')</code> it always passes</h1> <p>The only way to get consistent results is to avoid <code>element()</code>. If I expect(true).toBe(true) then 1 out of 1 tests always pass.</p> <h1>How can I debug this?</h1> <p>I'm at a loss for how to move forward. The test browser is correctly <em>displaying</em> my app, with the relevant 'a' element and everything. The test runner itself seems to only sometimes recognize that it should be running something and NEVER finds the <code>a</code> element. Is there a way to step through the test running process? Is this a common problem that happens when [x] is misconfigured?</p> <p>Thanks for any suggestions!</p> <h1><code>karma-e2e.conf.js</code></h1> <pre><code>basePath = '../'; files = [ 'test/lib/angular/angular-scenario.js', ANGULAR_SCENARIO_ADAPTER, 'test/e2e/**/*.js' ]; autoWatch = false; browsers = ['Firefox']; singleRun = true; proxies = { '/': 'http://localhost:3000/' }; urlRoot = "__karma__"; junitReporter = { outputFile: 'test_out/e2e.xml', suite: 'e2e' }; </code></pre>

    2. COI had not seen that question, thanks! Unfortunately I think my problem is different. The testing browser launches every time and I get no complaints about missing executables. I've also had karma installed globally the whole time.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
