Junit. Pulling my HAIR OUT!

**phil128** · 10-04-2010, 06:33 PM

Hello. I've downloaded the latest JUNIT and i'm trying to get it to work with eclipse. Currently i've got a basic class and a test class. The problem i'm having is when i try and run it i get the following error:

Java Code:

java.lang.NoClassDefFoundError: org/junit/runner/notification/RunListener
	at org.eclipse.jdt.internal.junit4.runner.JUnit4TestLoader.createTest(JUnit4TestLoader.java:41)
	at org.eclipse.jdt.internal.junit4.runner.JUnit4TestLoader.loadTests(JUnit4TestLoader.java:31)
	at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:452)

	at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390)
	at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197)

Here is my main class:

Java Code:

public class rectangle {

	/**
	 * @param args
	 */
	
	private double width;
	private double height;
	
	
	public rectangle(double width, double height)
	{
		this.width = width;
		this.height = height;
	}
	
	public double getWidth()
	{
		return width;
	}
	
	public double getHeight()
	{
		return height;
	}
	
	public void setWidth(double width)
	{
		this.width = width;
	}
	
	public void setHeight(double height)
	{
		this.height = height;
	}
	
	public double getArea()
	{
		return width * height;
	}
	
	public double getDiagonalLength()
	{
		return Math.sqrt(width*width + height*height);
	}
	
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		rectangle rec = new rectangle(2,3);
		
	}


}

My test Class

Java Code:

import static org.junit.Assert.*;

import org.junit.After;
import org.junit.Before;
import org.junit.Test;


public class rectangleTest {

	@Before
	public void setUp() throws Exception {
	}

	@After
	public void tearDown() throws Exception {
	}

	@Test
	public void testGetWidth() {
		fail("Not yet implemented");
	}

	@Test
	public void testGetHeight() {
		fail("Not yet implemented");
	}

}

I've imported junit via the preferencies->ant->runtime. And still i have no luck.

Could somebody please help me. Pleeeeeeeeease

The test case was the pre-generated test case. But i've tried it with a difference set of test cases and i still have the same error.
