By unit testing, I presume you refer to the process of writing a script to run a particular function or section of code through multiple scenarios and grade it's performance. If that's the case, you could, and may want to, do such testing without the use of JUnit. In my extremely limited knowledge of JUnit, there is frankly little that I can do with JUnit that I cannot do with my own custom program, and quite a bit that I would rather not have to run through JUnit.

What testing functionality are you looking for that JUnit gives you?
