noobie junit issue

[jay vas]

1) My IDE (eclipse) isn't prompting me to run this class as a test.... I'm wondering why ? I've also played with putting
annotations above the methods.

2) In general, if I'm not extending TestCase (due to multiple inheritance prevention), what is the convential way to
make a class Unit Testable ?

package code;

import java.util.LinkedHashSet;
import java.util.TreeMap;

import junit.framework.TestCase;

import org.junit.Test;

public class Example extends TestCase
{ 

  public void testDivideByZero() 
  {
    int zero= 0;
    int result= 8/zero;
  }
  public void testEquals() 
  {
    assertEquals(12, 12);
  }
}

I'm not quite sure why....

Jay,
What do you mean by prompting you to run as test? Run as JUnit isn't an option.

Adding annotations to a JUnit 3.8 style doesn't do anything. You need either what you have or to not extend test case and add annotations.

Eclipse typically offers Run As > JUnit in helios and galileo..... (see image).....

So I guess I'm confused about how / why extension of TestCase is ever necessary.... Is this just an artifact of old JUnit ?

Right. In Helios, I can run JUnit 4 style tests that way. I don't remember what version of JUnit was built into Galileo.

In JUnit 4, you can write tests in the old style or new style. Sometimes, one is using a library that forces extending in the 3.8 style so they kept it as an option.
