Junit Testing within local classes

[danboy4]

Hey there, I was wondering if anyone could possibly help me with writing jUnit tests for some of my code. I currently have one test calculating distance working fine. As some background, the code I need to write a test for moves a playerObject towards the closest barrier which it then changes colour when it touches. I'd like to write a jUnit test that checks to make sure that it's distance from the closest barrier is 0 and that the X and Y are changing. I would also like to write a new test to test if the playerObject changes colour when distance<delta. Here is my code:

if (playerObject.getX() < barriers[whereTo].getX()
							&& !(playerObject.getX() > barriers[(int) whereTo].getX()))
						playerObject.setX(playerObject.getX() + 0.30 * delta);

					if (playerObject.getY() < barriers[whereTo].getY()
							&& !(playerObject.getY() > barriers[(int) whereTo].getY()))
						playerObject.setY(playerObject.getY() + 0.30 * delta);

					if (playerObject.getX() > barriers[whereTo].getX()
							&& !(playerObject.getX() < barriers[(int) whereTo].getX()))
						playerObject.setX(playerObject.getX() - 0.30 * delta);

					if (playerObject.getY() > barriers[whereTo].getY()
							&& !(playerObject.getY() < barriers[(int) whereTo].getY()))
						playerObject.setY(playerObject.getY() - 0.30 * delta);
					
					if (currentDist < (delta)) {
						playerObject.setX(barriers[whereTo].getX());
						playerObject.setY(barriers[whereTo].getY());
						barriers[whereTo].setColour(0.1, 0.1, 0.1);
						next = true;
					}

Well, you haven't actually asked anything, really.
You haven't shown a unit test that you;re having problems with, just the code you want to test (and not even the method).

Unit tests test methods...but there is no method there.

Thanks for the reply Tolls,
So would you advise that i create a function that includes the aforementioned code? I can then test that?

I was under the impression i could test this using multiple tests but I don't know how to test inside a class inside a class.

Your tests are supposed to be testing that the interface does what it says it does.

If you have a method that "takes two ints and returns the sum" then you write a test for that.

You don't write tests for some random path through some bit of your code.
