This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori 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!
