title: Running unit tests in Pydev
body: <p>I am trying to run unit tests in Pydev using IronPython.</p>
  
  <p>When I try to run a test with Ctrl+F9 the following error message shows up in the Eclipse console window:</p>
  
  <blockquote>
    <p>AttributeError: 'module' object has no attribute '_getframe'</p>
  </blockquote>
  
  <p>I figured out that I have to invoke the IronPython interpreter with the '-X:Frames' argument.</p>
  
  <p>Setting up the arguments in the 'Arguments' tab under 'Run->Run Configurations...' doesn't work. They seem to disappear everytime I run (Ctrl+F9) and choose another test.</p>
  
  <p>Clicking 'Run->Run As->Iron Python unit-test' shows up more and more options to choose from.</p>
  
  <p>Is Eclipse/Pydev creating new run configurations everytime I run a different set of tests? How can I permanently pass the '-X:Frames' argument, so my tests will run under IronPython?</p>
  
  <p>(In Python the tests run without any problem.)</p>
