    <p>It turns out the 'start-server' and 'stop-server' goals are for starting/stopping SeleniumRC servers. This is <em>NOT</em> what I wanted, as all my tests use the WebDriver API instead.</p> <p>Apparently the 'xvfb' goal in the pom DOES start an Xvfb session during the specified lifecycle phase - I guess I just didn't see it before. And in it's configuration, you specify where to write a props file detailing which display Xvfb is running on. In the Java code, this file can be read and the value passed to the FirefoxBinary used when creating the WebDriver.</p> <p>The relevant pom.xml bits are as follows:</p> <pre><code>&lt;properties&gt; &lt;displayProps&gt;target/selenium/display.properties&lt;/displayProps&gt; &lt;/properties&gt; &lt;build&gt; &lt;plugins&gt; &lt;plugin&gt; &lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt; &lt;artifactId&gt;maven-surefire-plugin&lt;/artifactId&gt; &lt;configuration&gt; &lt;systemPropertyVariables&gt; &lt;display.props&gt;${displayProps}&lt;/display.props&gt; &lt;/systemPropertyVariables&gt; &lt;/configuration&gt; &lt;/plugin&gt; &lt;plugin&gt; &lt;groupId&gt;org.codehaus.mojo&lt;/groupId&gt; &lt;artifactId&gt;selenium-maven-plugin&lt;/artifactId&gt; &lt;version&gt;2.3&lt;/version&gt; &lt;executions&gt; &lt;execution&gt; &lt;id&gt;xvfb&lt;/id&gt; &lt;phase&gt;test-compile&lt;/phase&gt; &lt;goals&gt; &lt;goal&gt;xvfb&lt;/goal&gt; &lt;/goals&gt; &lt;configuration&gt; &lt;displayPropertiesFile&gt;${displayProps}&lt;/displayPropertiesFile&gt; &lt;/configuration&gt; &lt;/execution&gt; &lt;/executions&gt; &lt;/plugin&gt; &lt;/plugins&gt; &lt;/build&gt; </code></pre> <p>This starts Xvfb on the first free display (:20 or above) and writes the value to the props file that I read and use later in my Java code.</p> <pre><code>String xvfbPropsFile = System.getProperty("display.props"); FirefoxBinary ffox = new FirefoxBinary(); ffox.setEnvironmentProperty("DISPLAY", /*read value from xvfbPropsFile*/); WebDriver driver = new FirefoxDriver(ffox); </code></pre> <p>Now the driver will be in control of the Firefox instance spun up in the appropriate display. Voila!</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.

SQuiL has stopped working due to an internal error.

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