Running JUnit 4 from command line

1.) Download Junit 4.

2.) Write a test class :

import org.junit.Test;
import junit.framework.TestCase;
    
public class TestJUnit4 extends TestCase
{
    int value1 = 2, value2 = 3, expectedResult = 5;
    
    @Test
    public void testSuccess()
    {
        assertTrue(value1 + value2 == expectedResult);
    }
    
    @Test
    public void testFail()
    {
        assertTrue(value1 - value2 == expectedResult);
    }
}

3.) Compile it at from command line :

javac -cp .;c:\junit\junit4.jar TestJUnit4.java

4.) Run it :

C:\JavaProgs>java -cp .;c:\junit\junit4.jar org.junit.runner.JUnitCore TestJUnit4

This gives below result :

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

Installing ANT

1. Download ANT

2. Extract the downloaded zip file.

3. Set ANT_HOME environment variable pointing to your Ant location(like,C:/ant)

4. Now set Path variable pointing to your ANT bin directory(%ANT_HOME%\bin)

5. Test ANT at command prompt :
echo %ANT_HOME% //your current ANT directory
ant -version //version of the ANT

If you don't want to follow these steps, you can simply download and run the windows installer for ANT
