Since Microsoft created MSTest, I've been using it for unit testing. I never really used NUnit, and I just didn't like the need to have yet another tool installed on my dev box. I've only used the basic features of MSTest so far, and they have satisfied my needs, and I don't really know anything about NUnit.
Could someone list out some of the disadvantages and advantages of using MSTest and NUnit compared to each other?
Here is a nice blog which lists out some differences between MSTest and NUnit http://blogs.msdn.com/nnaderi/archive/2007/02/01/mstest-vs-nunit-frameworks.aspx
And this link here compares even more unit testing frameworks http://www.codeplex.com/xunit/Wiki/View.aspx?title=Comparisons
