If you run automated builds using NAnt, you may or may not know about the MbUnit Task you can add to NAnt. MbUnit has pretty good directions for how to do get their task setup. I've been out to their site a couple of times trying to remember the exact details of the mbunit NAnt task. Dru put the thought into my head, why not make the concept of running the tests a more generic and universal item so that you can just drop a couple of files into a project and be done? I thought about this for awhile...
