title: Idea run/debug py.test single test not the whole suite
body: <p>I'm creating a python test suite (using py.test). I'm coding the tests in Idea and I don't know how to debug a single test. </p>

  <p>This is my setting of the debugger. It runs the whole testsuite. So I have to run all the tests before it gets to the one I'm trying to debug.</p>
