title: How to test broadcast driver?
body: <p>I am wondering if its possible to test <code>ShouldBroadcast</code> in Laravel?
  My test will trigger the even that implements <code>ShouldBroadcast</code>, however, I've noticed that broadcasting didn't happen.</p>
  
  <p>Of course, the broadcasting event is working in the app it self.</p>
  
  <p>Has any one tried such test?</p>
