title: TestNG: Eclipse confused by JUnit
body: <p>I'm setting up tests with TestNG in an Eclipse project, but I get a strange error: When I try to generate a test class from a business class, I get a popup with a message saying "Grid not editable" (title) "The compilation unit is not compilable, or is not a sublcass of junit.framework.TestCase. Fix and tyr again" (body).
  Somehow, Eclipse seems to think I want to create JUnit classes, and I can't get why. Any clue?</p>
  
  <p>Configuration:</p>
  
  <ul>
  <li>Eclipse 3.6.0</li>
  <li>TestNG 5.14.10</li>
  </ul>
