I wanted to discuss the "mixed mode" feature you added to TestNG. Instead of adding JUnit into the JAR and getting TestNG to run JUnit tests, wouldn't it be more extensible to have each product run its own tests (unaware of the existence of the other)? The idea would be for Netbeans to launch TestNG for TestNG tests and JUnit for JUnit tests (similarly if a user is not using an IDE he's add two separate targets in his build.xml file). This way if some other test framework comes along in the future we don't end up with every framework having to know about everyone else (unnecessary coupling).
