Testing and debugging are crucial parts of mobile app development. React Native offers several tools for this purpose, including the built-in debugger, React Developer Tools, and integration with third-party testing libraries like Jest and Detox.
You can debug your React Native app by shaking your device (or pressing Cmd + D on iOS simulator or Cmd + M on Android emulator) to bring up the debug menu. From there, you can enable remote debugging, inspect elements, and more.
