Expo SDK 54 Test Issues

Goal

This repository provides a minimal reproduction of issues encountered when running tests with popular libraries after upgrading to Expo SDK 54 / React Native 0.81.

How to use it

The main branch contains only the basic setup for an Expo SDK 54 app with Jest and React Native Testing Library support.

Switch to the appropriate branch depending on the library whose issue you want to reproduce:

• flashlist-issue: reproduces an issue with @shopify/flash-list, where only the first 10 items are rendered during tests.
• carousel-issue: reproduces an issue with react-native-reanimated-carousel, where carousels are not rendered during tests.

Then, on each of the branches mentioned above, you can run the tests with:

yarn test

After running the tests, open the App.test.tsx.snap file to inspect what was rendered during testing.
