Hi Jeff. Yes, you have to tell the mock object what you're expecting it to return, so that the object being tested (your service in this case) interacts with the mock the same way it would interact with the real object. You'd do this in your unit test methods. So in your case, you'd mock a business object, then mock the DAO, and finally tell the DAO that when the service calls the method on it, it returns the business object. The whole point is that the only "real" object you're testing at a time is the object you actually want to test. Everything else is fake. Does that make sense or am I misreading your question?
