i want to use mocking in my unit tests.

Till now i more programmed 'tests' and not 'unittests' because i tested whole program flows, but reading discussions i can see the beauty of a mock object, from time to time.

But, looking around, there are a lot of frameworks available, and i want to make sure i start with a good one, because i'd like to invest time in learning a mock framework only once.

So as i said in the title, i'm a novice for mocking, using asp.net mvc, and don't think i'll be a hardcore mocker, investigating the edges of a mocking framework.

To give you an idea of what i like in the IOC frameworks i like unity and structuremap.
