I have a number of unit tests that rely on being run in a separate JVM as they are in Maven or Ant. When I set the fork option in IDEA to "class," it instantiates all the unit test classes, then says "Done: 0 of 106 (8.537 s)" The list of unit tests is displayed in the Run window, but none have been executed. I also get a message in the lower left corner that reads "Failed to start: 0 passed, 106 not started." Any advice would be greatly appreciated. I've tried a number of things and can't seem to get the tests to run. Thanks!
