/**
 * Test entering pip from an app via auto-enter property when navigating to home.
 *
 * To run this test: `atest WMShellFlickerTests:AutoEnterPipOnGoToHomeTest`
 *
 * Actions:
 *     Launch an app in full screen
 *     Select "Auto-enter PiP" radio button
 *     Press Home button or swipe up to go Home and put [pipApp] in pip mode
 *
 * Notes:
 *     1. All assertions are inherited from [EnterPipTest]
 *     2. Part of the test setup occurs automatically via
 *        [com.android.server.wm.flicker.TransitionRunnerWithRules],
 *        including configuring navigation mode, initial orientation and ensuring no
 *        apps are running before setup
