    <p>I'm adding Karma-based JS unit tests to Maven. I used the following configuration:</p> <pre><code>&lt;plugin&gt; &lt;groupId&gt;com.kelveden&lt;/groupId&gt; &lt;artifactId&gt;maven-karma-plugin&lt;/artifactId&gt; &lt;version&gt;1.0&lt;/version&gt; &lt;executions&gt; &lt;execution&gt; &lt;goals&gt; &lt;goal&gt;start&lt;/goal&gt; &lt;/goals&gt; &lt;/execution&gt; &lt;/executions&gt; &lt;configuration&gt; &lt;browsers&gt;Chrome&lt;/browsers&gt; &lt;/configuration&gt; &lt;/plugin&gt; </code></pre> <p>Tests work separately (without Maven) on my machine when I use <code>karma start karma.conf.js</code>, but with Maven I got the following error:</p> <pre><code>[ERROR] Failed to execute goal com.kelveden:maven-karma-plugin:1.0:start (default) on project web: There was an error executing Karma. Cannot run program "karma": CreateProcess error=2, The system cannot find the file specified -&gt; [Help 1] org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal com.kelveden:maven-karma-plugin:1.0:start (default) on project web: There was an error executing Karma. at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:217) ... Caused by: java.io.IOException: Cannot run program "karma": CreateProcess error=2, The system cannot find the file specified at java.lang.ProcessBuilder.start(ProcessBuilder.java:460) at com.kelveden.karma.StartMojo.createKarmaProcess(StartMojo.java:151) ... 22 more Caused by: java.io.IOException: CreateProcess error=2, The system cannot find the file specified at java.lang.ProcessImpl.create(Native Method) at java.lang.ProcessImpl.&lt;init&gt;(ProcessImpl.java:81) at java.lang.ProcessImpl.start(ProcessImpl.java:30) at java.lang.ProcessBuilder.start(ProcessBuilder.java:453) ... 23 more </code></pre> <p>Here is why I find it a bit strange: according to <a href="https://github.com/karma-runner/maven-karma-plugin/blob/master/src/main/java/com/kelveden/karma/StartMojo.java" rel="nofollow">this class</a>, the <code>karma.conf.js</code> should be found by default (<code>@Parameter(defaultValue = "${basedir}/karma.conf.js", property = "configFile", required = true)</code>). Also, I tried to pass the path, absolute and relative, in the <code>-DconfigFile=...</code> parameter, it didn't work. I used Windows, but I think it shouldn't be a problem. I'm not sure what exactly can be wrong in the configuration, an advice would be appreciated.</p>

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.
