[🐛] Jest Setup file is deleting `TurboModuleRegistry.get`, breaking test suites

[rodperottoni]

What happened?

In my Jest Config file, I am adding ./node_modules/react-native-google-mobile-ads/jest.setup.ts to my setupFiles config. This always worked for me until I decided to begin upgrading my libraries. That's when I started getting errors such as this in my test suite:

It took me a long time to find out the culprit, and apparently it's this file under react-native-google-mobile-adds. Notice how it assigns getEnforcing but not a get to the TurboModulesRegistry library:

jest.doMock('react-native', () => {
  return Object.setPrototypeOf(
    {
      Platform: {
        OS: 'android',
        select: () => {},
      },
      NativeModules: {
        ...ReactNative.NativeModules,
        RNAppModule: {
          addListener: jest.fn(),
          removeListeners: jest.fn(),
          eventsAddListener: jest.fn(),
          eventsNotifyReady: jest.fn(),
        },
        RNGoogleMobileAdsModule: {
          addListener: jest.fn(),
          removeListeners: jest.fn(),
          eventsAddListener: jest.fn(),
          eventsNotifyReady: jest.fn(),
        },
        RNGoogleMobileAdsInterstitialModule: {
          interstitialLoad: jest.fn(),
        },
        RNGoogleMobileAdsRewardedModule: {},
        RNGoogleMobileAdsConsentModule: {},
      },
      TurboModuleRegistry: {
        getEnforcing: () => {
          return {
            initialize: jest.fn(),
            setRequestConfiguration: jest.fn(),
            openAdInspector: jest.fn(),
            openDebugMenu: jest.fn(),
            setAppVolume: jest.fn(),
            setAppMuted: jest.fn(),
          };
        },
      },
    },
    ReactNative,
  );
});

I think we need to better document how to setup react-native-google-mobile-ads with Jest, as well as fixing this mock for future users.
