See also: http://www.pragmaticprogrammer.com, about the book "Pragmatic Unit Testing in Java with JUnit" by Andrew Hunt and Dave Thomas: ISBN 0-9745140-1-2 . http://www.pragmaticprogrammer.com/starter_kit/ut/
One of the books in ThePragmaticStarterKit? series, covering unit testing in Java. While the examples are Java-specific, most of the advice is not specific to any particular language.
After reading ThePragmaticProgrammer and PragmaticVersionControl?, I was looking forward to this book. Unfortunately, our team uses CeePlusPlus and CVS, so unit testing with Java is only helpful in a very abstract sense. I would love to read (the non-existent)"Pragmatic Unit Testing in C++ with CppUnit" or something similar. -- LayneThomas
