React Native 0.80.0's jest setup is broken due to missing mock files

[byCedric]

Description

We've upgraded React Native to 0.80.0 in https://github.com/expo/expo and are seeing some test failures due to incorrect mock references.

• It seems that '[skip ci] [RN] Replace .npmignore files, ignore all test/fixture/docs directories #50784 excluded actively used files, like react-native/Libraries/Components/RefreshControl/__mocks__/RefreshControlMock (here).
• This seems the be fixed in RN: Refactor Jest Default Mocks #51669, but this doesn't seem to be available for 0.80.x yet.

Steps to reproduce

1. Create a React Native project
2. Setup a Jest test
3. Import react-native/Libraries/Components/RefreshControl/RefreshControl
4. Causes the error here
   

Or, use the Expo repository:

1. git clone https://github.com/expo/expo ./expo
2. cd ./expo
3. yarn --frozen-lockfile
4. cd packages/expo-router
5. yarn jest smoke

Looks like there's an open 0.80 pick request: #51942, which includes a more targeted fix for this:

• Move RefreshControlMock into Jest preset files #51530

@byCedric, the pick request for 0.80 mentioned by Alex is:

• [0.80] Move RefreshControlMock into Jest preset files reactwg/react-native-releases#983

Does that suffice or do we also need a pick request for #51669 ?

[huntie]

@fabriziocucci It should suffice. I also added missing test coverage for our Jest preset shortly after this was introduced — #51534.

[byCedric]

Yep, that should suffice!
