MbUnit v3 and optional TestFixture
If you have not already done so, check out Jeff's post on changes to make TestFixture optional. As Jeff notes, Jim and Brad took this line in XUnit and after consultation it was decided for MbUnit to support this. Note, it's optional so your existing tests won't break but if refactoring it out makes sense then it is available for you to do so. If you do have any thought's and feelings on this do let us know.
