Specification – moving backward

Now that we have a forward movement specified and implemented, the backward movement should almost be the same:

public void whenMoveBackwardThenBackward() {
  Location expected = location.copy();
  expected.backward();
  ship.moveBackward();
  assertEquals(ship.getLocation(), expected);
}
