Well, according to Scott Hanselmann MbUnit is supposed to be Unit Testing on Crack – I would prefer it to be on steroids (as I consider that to be more political correct, because I wouldn’t want to have a drug addict on my team :)) ). But anyway!
So I checked out MbUnit, and so far I think it has quite some neat features. After working for some years with NUnit I long for something new, which satisfies more complex requirements for unit-testing. Event though there are a couple of extensions to NUnit to enabled row-based testing, I consider MbUnit as an alternativ.
I will most definitely give it a try in one of my next projects.
