In the last IVBUG meeting I ran into the guy who created what he called “The Best Unit Test framework in town”. His name is Bnaya and he is one cool dude who is excited about technology in the way that I recognize in myself. He even volunteered to give a talk in the user group about it. It will probably happen in the near future.
Looking at the framework he built, granted, it's not the best name for it, but still. If you've used NUnit or csUnit, you'd do well to stop by there and see all the cool test ideas he implemented. For example, security, multi threading and so on. Very nice, and very slick idea. It's pretty rough around the edges but it shows of some very good ideas for the future of test driven code.
