That's a good idea but doesn't apply when there's inheritance between  
test classes (and ISPN uses inheritance).
Eg.

  abstract class Base {
    public void testMethod(){}
}

@Test
public class A extends Base{}

@Test
public class B extends Base{}

Now test method will be run twice, and the stack trace won't let you  
make the difference between it being run in the context of class A or  
of class B.
But yep, in all other scenarios this is a very useful mechanism.
