I’ve been using xUnit.Net for a while now. It’s just a tiny bit cleaner and slightly less abrasive than other .Net unit testing frameworks. Leaving out unnecessary stuff like [TestFixture] and shortening Assert.AreEqual to the equally clear but shorter Assert.Equal don’t seem like big improvements but when you type them several times a day tiny improvements start to add up. I also like the use of the [Fact] attribute instead of [Test]. It shifts the focus from testing to defining behavior. So how do we get all this goodness working with the Visual Studio 2010 beta?
