- * This test verifies that the animation events are firing as expected.

- * This test runs three seperate animations of a robot.
- *
- * Animation 1:
- * - Starts at 0, 0
- * - Moves to 100, 100
- * - Duration: 500ms
- * - Delay: 500ms
- * - Tests that the 'animating' event is fired after the delay
- * - Tests that the waitUntilStopped() promise resolves when the animation finishes
- *
- * Animation 2:
- * - Starts at 100, 100
- * - Moves to 0, 0
- * - Duration: 500ms
- * - No Delay
- * - Tests that the 'animating' event is fired (even if no delay)
- * - Tests that the 'stopped' event is fired when the animation finishes
- *
- * Animation 3:
- * - Starts at 0, 0
- * - Moves to 100, 100
- * - Duration: 500ms
- * - No Delay
- * - Tests that the 'stopped' event is fired when stop() is called before the
- *   animation finishes
- * - Robot resets to 0, 0 when stop() is called
