A great and grad web testing environment for .net is WatiN. It enables you even to read out values on pages and create a full web regression testing tool. Unfortunately the second version if the test recorder is still in beta and quite unusable but working with the 1.0 version makes real input - output test for web forms very easy. All of this in combination with a Testing suite like nUnit makes regression testing a quick and easy to handle task! There is even a free NUnit integration in Visual Studio 2008! 

I just love it!
