I\'m looking to introduce a unit testing framework into the mix at my job. We\'re using Visual Studio 2005 (though we may be moving to 2008 within the next six months) and
VSTT 2010 (Visual Studio Team System Test) should be a good bet if you are looking for functional test automation. Web services testing, UI testing, BizTalk testing and data-driven testing support. Please look at VSTT.
