Summary: The RN OSS release process includes manual testing that a new template app can be started under various platforms, JS engines, etc. This should ideally be automated, to help reduce wasted engineer-time, and to allow reliably increasing release velocity. `react-native-windows` does already have tests to create and build template projects across our matrix, but they do not do any runtime validation on the newly created app. Adding a `testID` to the new app screen header gives us something to search for in black-box testing to validate that the app started successfully. This should help catch cases where a sample project in repo has changes not reflected in a newly created template app. ## Changelog <!-- Help reviewers and the release process by writing your own changelog entry. For an example, see: https://github.com/facebook/react-native/wiki/Changelog --> [Internal] [Added] - Add testID to NewAppScreen Header Component Pull Request resolved: https://github.com/facebook/react-native/pull/31652 Test Plan: Did not manually validate the change, though did check that `ImageBackground` forwards props to `Image`, and that `Image` is aware of `testID` and will forward to the native component.
