Pragmatic Unit Testing with TestNG and EasyMock

You've heard about unit testing but were daunted when it came time to put the pedal to the metal. That's because JUnit is just one tool and there's others you need to learn about, including the wonderful and wierd EasyMock and the easy and powerful TestNG.

Unit testing with JUnit 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 wierd 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 also leave JUnit behind and investigate using TestNG, a modern and improved test framework. We'll then learn how to tame EasyMock's awkward API with some modest refactoring and naming conventions.
