Ant

I'm finally starting the coding of a web application for work, that'll sooner rather than later be put up on the Internet. We're doing unit testing with jUnit and the set up isn't too bad. What's nice is using Ant as the build tool. It will find the test cases you create and automatically run them. So after the initial set up, you just add a new unit test and it gets run on your next build. Much better than the C++ way, where you have to manually add the test cases.
