I wrote a new article on - More on Unit Testing : TestContext in my blog in weblogs.asp.net . In that article , you can see what is TestContext of VSTS unit testing framework and how you can use TestContext to leverage writing effective unit tests for your application in different scenerios ranging from normal unit test to Data Driven and Asp.net unit test.
Don’t forget to check it out. I would really appreciate any comments or suggestion related to this topic.
