I'm just experimenting with easy mock (using the class extensio as well) to see if it's robust enough for us to use for our testing.

I wrote the following test in my test class:

			

			public void testAttack(){
			

			Player player = new Player(20);
			

			Orc orc = new Orc(20);
			

			player.setDie(die);
			

			die.roll(); //An isntance of Die.class - my mock object
			

			control.setReturnValue(14);
			

			control.setReturnValue(8);
			

			control.setReturnValue(10);
			

			control.setReturnValue(5);
			

			control.setReturnValue(14);
			

			control.setReturnValue(3);
			

			control.setReturnValue(17);
			

			control.setReturnValue(14);
			

			control.replay();
			

			player.attack(orc);
			

			System.out.println("Player: " + player.getHealth());
			

			System.out.println("Orc: " + orc.getHealth());
			

			assertTrue("Player should have been hurt and Orc Killed",((player.getHealth()== 17))&&(orc.isDead()));
			

			control.verify();
			

			}
		

It's just an experiment inspired by the chapter on Mock objects in Test Driven development by David Astels.

The Die class normally returns a random number, but here I was expecting the above returns from the mock object.

Sometimes it returns as expected, but jsut as often it return a random number - the test therefore fails every time...

Can anyone suggest why it is not returning as expected every time...?
