title: How to run single test method with phpunit?
body: <p>I am struggling to run a single test method named <code>testSaveAndDrop</code> in the file <code>escalation/EscalationGroupTest.php</code> with <code>phpunit</code>. I tried the following combinations: </p>
  
  <pre><code>phpunit EscalationGroupTest escalation/EscalationGroupTest.php --filter=escalation/EscalationGroupTest.php::testSaveAndDrop
  phpunit EscalationGroupTest escalation/EscalationGroupTest.php --filter=EscalationGroupTest.php::testSaveAndDrop
  phpunit EscalationGroupTest escalation/EscalationGroupTest.php --filter=EscalationGroupTest::testSaveAndDrop
  phpunit EscalationGroupTest escalation/EscalationGroupTest.php --filter=testSaveAndDrop
  </code></pre>
  
  <p>In each case <em>all</em> test methode in the file <code>escalation/EscalationGroupTest.php</code> are executed. How to select just ONE method instead?</p>
  
  <p>The name of the class is <code>EscalationGroupTest</code> and the version of <code>phpunit</code> is 3.2.8.</p>
