title: Keep getting 'You have requested a non-existent service "test.client"' in Symfony2 Beta3
body: <p>I'm trying to setup a unit test but whenever I run "phpunit -c app" I get this error:</p>
  
  <blockquote>
    <p>Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException: You have requested a non-existent service "test.client".</p>
  </blockquote>
  
  <p>The code in my test case is just:</p>
  
  <pre><code>public function testNonAuthenticatedPathsIndex()
  {
      $client = $this-&gt;createClient();
  }
  </code></pre>
  
  <p>If I don't make the call to createClient everything runs correctly. I've checked AppKernel.php to make sure the FrameworkBundle (I believe that's where this service is defined) is definitely still in there and it is.</p>
  
  <p>I'm a bit confused as to what might be causing this as I've managed to do this kind of thing before.</p>
  
  <p>Thanks for any help.</p>
