Unit Testing - UQdeco2800/2021-studio-6 GitHub Wiki

Most of the provided game and engine are heavily unit tested, and it is recommended that you do the same for any additions you make. Try to follow this checklist to avoid common mistakes:

• All tests should should extend from GameExtension, using the @ExtendWith(GameExtension.class) annotation. This ensures that the correct mocking of underlying graphics is done, and that the service locator is cleared between tests.
• When testing anything that relies on time, use ServiceLocator.getTimeSource() as your time source. Then in your tests you can provide a custom timesource with hardcoded values. You should never have tests that rely on real time passing.
• If the code you are testing relies on the service locator, make sure you initialise the necessary services. All services will be null by default.
