junit.org Software Testing Unit Testing Framework Java Programming

JUnit

JUnit is a simple framework to write repeatable tests. It is an instance of the xUnit architecture for unit testing frameworks. JUnit promotes the idea of 'first testing then coding', which emphasizes setting up the test data for a piece of code that can be tested first and then implemented. This approach is like 'test a little, code a little, test a little, code a little', which increases programmer productivity and stability of program code that reduces programmer stress and the time spent on debugging.
