Hi!
I wondered which Unit testing framework would be a good one to get really familiar with? I know this might be a question of opinion, but I thought I'd ask anyways. I know that I will need to do it someday, so I might as well learn to use it. I know that there is quite a few out there, but which one is effective for C# development?
From this question I can see that Unit testing is necessary, but personally I haven't used it. So that's why I ask this question.
Personally, I prefer the Visual Studio Unit Testing Framework, for two main reasons:
Having said that, pretty much any unit testing framework will do the trick, the important thing is to have tests!
Dont get stuck on choosing a framework. Just pick one and start testing - their not all that different. When you have written tests for a while, you will know what to look for, to suit your needs.
Personally i have found xUnit, Testdriven.Net and Moq to be a very flexible set of test tools.

There are a few reasons for testing, thus a few testing environments. Plus, there are levels of testing, like simple, stubs, and mocks. For example, you could test behavior rather than state.
As far as function, I usually use the Visual Studio built in setup, add a reference to the NUnit dll, and change the c# annotations to be NUnit. This is because I like testing outside of Visual Studio, especially when it involves others on my team (and we didn't buy the team edition of VS yet).
I use NUnit for the testing framework and ReSharper for integrating it into VS (and everything else ReSharper does).
Use MbUnit (with Gallio), NUnit, MsTest or xUnit. You can combine several unit tests. I use NUnit for TDD
I've decided to stick with NUnit because ReSharper provides native IDE support (which saves a lot of time). It's also supported by TeamCity in running and reporting automated tests.
