## JDT JUnit integration

JUnit is a simple test framework used to write repeatable tests.

The JDT tools include a plug-in that integrates JUnit into the Java IDE. The JUnit plug-in allows you to define regression tests for your code and run them from the Java IDE.

To learn how to use JUnit in the Java IDE, see Creating JUnit tests. The topics in this guide discuss how to interact programmatically with the JUnit IDE plug-in.
