This is the work of an expert on the subject. Made as simple as possible, but no simpler. It covers what to test and how to test. More than just using the JUnit tool, it explains how you can safely and repetitively test difficult classes that perform updates deletes or handle volitile data. Covers testing with Cactus, Servlets, JSP's, EJB's and stand-alone console programs. Everything you need to get the job done with style and quality.
