Running JUnit 3 from command line

1.) Download Junit 3.

2.) Write a test class :

import junit.framework.TestCase;


public class TestJUnit3 extends TestCase
{
int value1 = 2, value2 = 3, expectedResult = 5;


public void testSuccess()
{
assertTrue(value1 + value2 == expectedResult);
}


public void testFail()
{
assertTrue(value1 - value2 == expectedResult);
}
}

3.) Compile it at from command line :

C:\JavaProgs>javac -cp .;c:\junit\junit3.jar TestJUnit3.java

4.) Run it :

C:\JavaProgs>java -cp .;c:\junit\junit3.jar junit.textui.TestRunner TestJUnit3

This gives below result :
