		/**
		* Integration test cases for the Scene Framework.
		*
		* Principles
		* * All test cases here should be done from the perspective of the view-models of the system.
		* * Focus on happy paths, let smaller unit tests focus on failure cases.
		* * These are _integration_ tests and, as such, are larger and harder to maintain than unit tests.
		* Therefore, when adding or modifying test cases, consider whether what you're testing is better
		* covered by a more granular unit test.
		* * Please reuse the helper methods in this class (for example, [putDeviceToSleep] or
		* [emulateUserDrivenTransition]).
		* * All tests start with the device locked and with a PIN auth method. The class offers useful
		* methods like [setAuthMethod], [unlockDevice], [lockDevice], etc. to help you set up a starting
		* state that makes more sense for your test case.
		* * All helper methods in this class make assertions that are meant to make sure that they're only
		* being used when the state is as required (e.g. cannot unlock an already unlocked device, cannot
		* put to sleep a device that's already asleep, etc.).
