title: Behat testing in Symfony2 displaying unwanted debug info
body: <p>When I am running Behat tests in my Symfony2 project I get lots of unwanted debug lines like the following:</p>
  
  <pre><code>[2013-02-01 17:07:50] request.INFO: Matched route "homepage" (parameters: "_controller": "Symfony\Bundle\FrameworkBundle\Controller\RedirectController::redirectAction", "route": "Acme_tasks_tasks", "permanent": "true", "_route": "homepage") [] []
  [2013-02-01 17:07:51] security.DEBUG: Read SecurityContext from the session [] []
  [2013-02-01 17:07:51] security.DEBUG: Reloading user from user provider. [] []
  [2013-02-01 17:07:51] security.DEBUG: Username "john" was reloaded from user provider. [] []
  [2013-02-01 17:07:51] security.DEBUG: Write SecurityContext in the session [] []
  </code></pre>
  
  <p>My <code>behat.yml</code> looks like this:</p>
  
  <pre><code>default:
    formatter:
      name: progress
    extensions:
      Behat\Symfony2Extension\Extension:
        mink_driver: true
        kernel:
          env: test
          debug: false
      Behat\MinkExtension\Extension:
        base_url: 'http://local.acme.ch/app_test.php/'
        default_session: symfony2
        javascript_session: selenium
        selenium:
          host: 33.33.33.1
          port: 4444
  </code></pre>
  
  <p>As you can see I already turned off the kernel's debugging mode Where could all this stuff come from?</p>
  
  <p>My installation is based on Behat's Symfony2 Extension.</p>
