JUnit comes integrated with Eclipse, NetBeans and IntelliJ. You can write the JUnit tests manually, but these IDEs make it much easier. This video takes a quick look at each of these IDEs. We start with Eclipse by adding a new project. Next, we will walk through the steps to create a unit test using the JUnit framework.
