title: PHPUnit via Composer and PhpStorm
body: <p>I'm now trying for hours to setup PhpStorm for unit testing. Whatever I do, I get this</p>
  
  <pre><code>Process finished with exit code 1
  Cannot find PHPUnit in include path ...
  </code></pre>
  
  <p>PHPUnit is (via command line) accessible from anywhere; I've set the correct include path and have added PHPUnit to the external libraries. No chance.</p>
  
  <p>Is it possible at all or does it only work with installations via PEAR? I've worked through all related questions here, am on Mac and PHPUnit is running smoothly via CLI.</p>
