/**
 * Test entering pip from Netflix app by interacting with the app UI
 *
 * To run this test: `atest WMShellFlickerTestsPipAppsCSuite:NetflixEnterPipTest`
 *
 * Actions:
 * ```
 *     Launch Netflix and start playing a video
 *     Go home to enter PiP
 * ```
 *
 * Notes:
 * ```
 *     1. Some default assertions (e.g., nav bar, status bar and screen covered)
 *        are inherited from [PipTransition]
 *     2. Part of the test setup occurs automatically via
 *        [android.tools.flicker.legacy.runner.TransitionRunner],
 *        including configuring navigation mode, initial orientation and ensuring no
 *        apps are running before setup
 * ```
