How Do I Run JUnit Tests from Command Window?

To run JUnit tests from a command window, you need to check the following list:

1. Make sure that JDK is installed and the "java" command program is accessible through the PATH setting. Type "java -version" at the command prompt, you should see the JVM reports you back the version string.

2. Make sure that the CLASSPATH is defined as shown in the previous question.

3. Invoke the JUnit runner by entering the following command:

java org.junit.runner.JUnitCore <test class name>
