+/**
+ * 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.).
