title: passing test.includes into intellij idea test runner parameters
body: <p>for example, in ant i would use something like</p>
  
  <p>fileset dir="src/tests" includes="${test.includes}" excludes="${test.excludes}"/></p>
  
  <p>in the junit task. there is a Test Runner Parameters field in the Run Configurations in Intellij, but i cant seem to find how to pass that sort of information in. </p>
  
  <p>basic use case: i have abstract tests which have to extend TestCase, but are being run by intellij's test runner (and failing with "no tests found.."). </p>
  
  <p>if anyone knows how to do this.. it would be good :)</p>
