0.85/0.86/0.87-nightly missing @react-native/jest-preset from devDependencies #221
Description
Description
looks like every nightly and new rc release since
- Split out Jest preset to
@react-native/jest-presetreact/react-native#55169 - https://www.npmjs.com/package/react-native/v/0.85.0-nightly-20260217-db45c280e
ships with
- missing @react-native/jest-preset
- failing test script
we should merge
ideally before 0.87-stable to prevent future
- 0.86.0 rc.0-3 and latest missing @react-native/jest-preset from devDependencies #219
- 0.85.0-rc missing @react-native/jest-preset from devDependencies #211
then likely extend scripts\__tests__\package_json-test.js
to ensure all current @react-native/... scoped packages are present
i considered extending github.com/facebook/react-native/blob/main/.github/workflows/test-all.yml
since neither test_e2e_android_templateapp nor test_e2e_ios_templateapp cover yarn test
but a future breakage here causing all facebook/react-native PRs to break is a risk not worth it
