JUnit is an automated unit testing framework for Java™. JUnit is used on nearly all open and many closed source projects to ensure previously discovered bugs do not reenter the system.
At Core Developers Network we use JUnit extensivly, and have written extensions to it for J2EE applications. We can help you design and implement an effective testing strategy for your application based on JUnit.
