This week's book giveaway is in the OCMJEA forum. We're giving away four copies of OCM Java EE 6 Enterprise Architect Exam Guide and have Paul Allen & Joseph Bambara on-line! See this thread for details.
It's a little like the Parameterized Test Case pattern in JUnit. See this DataProvider Test NG thread that discusses the @DataProvider. One of the posters is the creator of TestNG so it comes straight from the source!
