I'm beginning to get involved with JUnitTesting. It looks like a very powerful and useful tool. I was wondering, what would be a good JUnit reference book to add to my library? Website suggestions are also welcome. Thanks.
The JavaRanch Bunkhouse puts JUnit books into this Miscellaneous section. There you'll find reviews of a number of JUnit books. I personally own and enjoyed "JUnit in Action" and "JUnit Recipes", but there are several more excellent books reviewed there.
