/**
 * Test launching an app from the recents app view (the overview)
 *
 * To run this test: `atest FlickerTests:OpenAppFromOverviewTest`
 *
 * Actions:
 *     Launch [testApp]
 *     Press recents
 *     Relaunch an app [testApp] by selecting it in the overview screen, and wait animation to
 *     complete (only this action is traced)
 *
 * Notes:
 *     1. Some default assertions (e.g., nav bar, status bar and screen covered)
 *        are inherited [OpenAppTransition]
 *     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
