Guerilla Unit Testing Part 2: The Weird and Wonderful EasyMock

In part two (of two) we go in depth on EasyMock, the weird and wonderful tool for creating mock objects on the fly. We'll do a good bit of live coding as we examine how to use, tame and extend this powerful tool.

Unit testing with only gets you so far; even when you've refactored your code and hidden all your implementations behinds interfaces you are still stuck with the problem of testing the individual pieces. If you've hit this point and despaired, know that there are tools to help … including the weird and wonderful EasyMock. We'll discuss unit testing in general, and how EasyMock is used to to generate mock objects, allowing you test each class in isolation. We'll be doing some live coding to show you step-by-step how to build up a unit test, interpret EasyMock's baffling error messages, and set yourself up for easy reuse of testing code.
