There are really several types of mock objects that you have at your disposal - Mocks, and Stubs are the two main types. the emphasis of unit testing is just that - to test the unit. If you test a (e.g.) business logic component, then you'll end up testing it, plus any data access code you write, plus any SQL stored procs etc in the process. Using a mock object allows you to control the environment around the component you're testing. The wikipedia article seems like a good jumping off point. I also found the book extreme programming tools for Java quite helpful. http://en.wikipedia.org/wiki/Unit_testing HTH, and good luck. Andrew Hi Jeremy,

I always thought I was a moderately capable coder, and recently decided to switch from VB to C#. On making the change, I also decided to do things "properly" - particularly the question of unit testing. I've got the gist of the principles of unit testing, but can't get my head around Mocking. I have also realized that I am nothing more than a "hobby programmer" - a bit sad after doing this "part time" for so many years. I'm working my way though "Code Complete" but in the meantime would really appreciate it if you could point me in the direction of a good book, articles etc that will throw light on this for me? My particular interest is Linq for SQL.

I am not able to do the same, as its implementing IQueryProvider and the CreateQuery too has two arguments - IQueryProvider and an Expression. Can you please give a link to your source code too? It would be really, really helpful for me Thanks did u try the same with Visual Studio 2008?
