NUnit
I just started to use NUnit and NUnitAddin. They are great!
Simplicity is the key word as far as they are concerned.
I'd advise anyone to take a look at these great tools for unit testing!
Just follow the NUnit tutorial (included QuickStart.doc file), then play with NUnitAddin. A documentation for NUnitAddin is missing though (even a simple one would be nice, Jamie :-) ).
Here is what NUnitAddin provides in Visual Studio:
- "Run Tests" command in context menus (in Solution Explorer, in text editor)
- Wizards for new test project ("Test Suite") and test class ("Test Fixture")
Nota Bene: Peter Provost has written a good article on "Test-Driven Development In .NET" which can be found on his web site or on The Code Project.
