/**
 * This test tests the transition type selection logic in ActivityManager/WindowManager.
 * BottomActivity is started first, then TopActivity, and we check the transition type that the
 * system selects when TopActivity enters or exits under various setups.
 *
 * Note that we only require the correct transition type to be reported (eg. TRANSIT_ACTIVITY_OPEN,
 * TRANSIT_TASK_CLOSE, TRANSIT_WALLPAPER_OPEN, etc.). The exact animation is unspecified and can be
 * overridden.
