Code-Reuse in unit tests is more important than you think

Scott Bellware mentions how he really likes the new ideas in XUnit.NET, especially the lack of [Setup] and [TearDown] methods. (Brad Wilson wrote in the comments to my post about XUnit.NET that you can mimic this behavior by using the constructor of the test class and the IDisposable.Dispose() method...
