JUnit is a simple, open source framework to write and run repeatable tests. It is an instance of the xUnit architecture for unit testing frameworks.
JUnit features include:
Assertions for testing expected results
Test fixtures for sharing common test data
Test runners for running tests
JUnit has been important in the development of test-driven development, and is one of a family of unit testing frameworks collectively known as xUnit that originated with SUnit.
JUnit tests can be run from the command line or from within Eclipse. To run JUnit tests from the command line, you will need to download and install JUnit. The latest version is available from JUnit.org.
Once JUnit is installed, you can run your tests from the command line or from within Eclipse. To run a JUnit test from the command line, you will need to provide the name of the test class, like this:
java org.junit.runner.JUnitCore MyTest
To run JUnit tests from within Eclipse, you will first need to create a new Java project. Once the project has been created, you can add your JUnit test classes to the project. To run a JUnit test from within Eclipse, right-click on the test class and select Run As > JUnit Test.
