title: Testing a build of jQuery
body: <p>How can I run the qUnit tests shipped with jQuery. I don't understand why there are PHP files, for example here <a href="https://github.com/jquery/jquery/tree/master/test/data" rel="nofollow">https://github.com/jquery/jquery/tree/master/test/data</a>.</p>
  
  <p>Is there some sort of script that will run all the tests?</p>
