title: JUnit test for BlockingQueue interface
body: <p>Is there already some existing <code>JUnit</code> test for testing a <code>BlockingQueue</code> interface? Some class I can download, press play and then it turns red (hopefully green :-)), without me having to spend a day thinking of all test cases?</p>
  
  <p>I googled but couldn't find anything.</p>
  
  <p>some ideas?</p>
  
  <p><strong>EDIT:</strong> The test case that <strong>G_H</strong> provided was very good for debugging the basics. Is there maybe still a good test for heavy multithreaded use, that really provokes races and deadlocks?</p>
