JUnit 3 problem

[Jerry Van]

When I run this Junit 3 test class I get the failure "No tests found". However, mt method starts with the "test" word:

package org.eclipse.lifegame.domain;
 
import junit.framework.TestCase;
 
public class TwoDimensionalBirthRuleTest extends TestCase {
 
int[][] boardCells = {
 
{0, 1, 0, 0, 0, 1, 0, 1, 0, 1},
 
{1, 1, 0, 0, 0, 1, 1, 1, 0, 1},
 
{0, 0, 0, 0, 0, 0, 0, 0, 0, 1},
 
{0, 0, 0, 1, 1, 1, 0, 0, 0, 1},
 
{0, 0, 0, 1, 0, 1, 0, 0, 0, 1},
 
{0, 0, 0, 1, 1, 1, 0, 0, 0, 1},
 
{0, 0, 0, 0, 0, 0, 0, 0, 0, 1},
 
{0, 0, 0, 0, 0, 0, 0, 0, 0, 1},
 
{1, 1, 1, 0, 0, 0, 0, 0, 1, 1},
 
{1, 0, 1, 0, 0, 0, 0, 0, 1, 0}};

public boolean testTwoDimensionalBirthRule(){
boolean result;
TwoDimensionalBirthRule rule = new TwoDimensionalBirthRule();
result = rule.doesApply(boardCells, 0, 0);
return result;
}
}
 

So, my question is, what might be causing this failure? Let me know if you need to see any other classes of my LifeGame project.

Thanks,

Jerry,

Junit 3 tests need to be in the format

public void testMethodName() {}

Yours has boolean as the return. I suspect that's why Junit doesn't find any test cases.

You should use asserts within the test method to verify the code is working as expected.

Yep, that is the problem.
The method should not have a return value (and no arguments).
Also as mentioned, you normally want to test something in your method and therefore use some assert method. In this case it looks like you want to do something like:

assertTrue(rule.doesApply(boardCells, 0, 0));

Did you read this article on the JUnit website?

Moving to our testing forum.

I apologize for starting this topic in the wrong forum. Thanks for the correction, and thanks to all who replied. By using your replies I got it to work.

Love that java!

Cheers,
Jerry
