Instead of using confusing terms like Mocking and Stubbing which is basically the same. Caricature tries to unify those concepts by using a term of Isolation. When you’re testing you typically want to be in control of what you’re testing. To do that you isolate dependencies and possibly define return values for methods on them. At a later stage you might be interested in which method was called, maybe even with which parameters or you might be interested in the amount of times it has been called.
