junit testing with mockobjects

Question

we are planning to bring Junit testing into our project and we just realised that to do junit testing we need to create lot of mockobjects. Can anyone suggest me a good tool or framework that can create these mockobjects for the classes that i will be performing unit testing?

Answer 1

One more thing, you don't need to create "lots" of mock objects, but just enough. If you're completely new, then start with "straight" unit tests and move to testing interactions when you've had some practice.
