Download the latest VERSION of JUnit, REFERRED to below as junit.zip.
Unzip the junit.zip distribution file to a directory referred to as %JUNIT_HOME%.
Add JUnit to the classpath − set CLASSPATH=%CLASSPATH%;%JUNIT_HOME%junit.jar
Test the installation by running the sample tests distributed with JUnit (sample tests are located in the installation directory directly, not the junit.jar file). Then simply type − java org.junit.runner.JUnitCore org.junit.tests.AllTests
All the tests should pass with an "OK" message. If the tests don't pass, VERIFY that junit.jar is in the CLASSPATH.
