Cannot find module 'warnOnce' from 'react-native-implementation.js' #23943
Description
🐛 Bug Report
When requiring react-native in node context (e.g. jest) module warnOnce cannot be found.
● Test suite failed to run
Cannot find module 'warnOnce' from 'react-native-implementation.js'
To Reproduce
TestFile.js
import { PixelRatio } from 'react-native'
export default class TestFile {
}
TestFile.test.js
import TestFile from './TestFile'
test('test', () => {
...
})
Expected Behavior
warnOnce should be found and loaded just like invariant.
Workaround
As a workaround I'm mocking react-native dependency with jest.doMock('react-native', () => reactNativeMock))
