A couple of years ago I made the decision to use MbUnit as my unit testing framework. At the time, NUnit had appeared to be stagnating for quite a while, whereas Peli was regularly pushing MbUnit forward with new features. But to be honest neither framework has really made big strides since then. So I was happy to read about xUnit.net the other day, and even happier to read Andy Stopford’s response reminding us that MbUnit Gallio is still under development (sorry, couldn’t find a decent overview to link to). It’s been talked about for a while, but I think the fact that xUnit.net binaries are already available is going to squeeze some binaries out of the MbUnit Gallio team very soon.
Good luck to both teams, and although I’m sure there’s room for both frameworks (and MSTest I suppose, especially when it’s in Visual Studio Pro) it’s nice to have a bit of competition!
