JUnit is an open source testing framework developed by Erich Gamma and Kent Beck. The JUnit framework uses Java’s reflection capabilities to run unit tests created in your classes.
The JUnit framework provides you with the ability to create test cases and group those test cases into a test suite. The test suite can then be executed as many times as required.
JBuilder enhances the JUnit framework by providing wizards to build skeleton unit test code, create test suites, and provide utility functions for comparing JDBC and JNDI results.
The JUnit package junit.framework contains the classes TestCase and TestSuite. These classes are used in the creation of unit tests and are recognized by JBuilder as unit test classes.
