Issue configuring test with Jest and RN 0.76.3

[jloracudris]

Current behaviour

Im trying to configure unit test with Jest but the tests are complaining that they dont understand React Native paper elements, so i figured that i had to mock all the components, but trying to create the actual mock has not work as expected. im getting this error

if i remove const originalModule = jest.requireActual("react-native-paper"); and mock them manually they work

Im having a weird error on this file (node_modules/react-native/src/private/animated/NativeAnimatedHelper.js:100:38) and im really lost here tbh

Expected behaviour

being able to configure tests

How to reproduce?

try to mock react native paper in a jest.setup.js file like this

I saw this issue and read it multiple times first: facebook/react-native#47421

then i realized that i needed to update node version to >= 20, also i was using npm then i switched to yarn and this problem wasnt there anymore, so maybe its something related to npm cache or npm itself (which i dont beleive is the case)

TL:DR:

• Remove package-lock
• Remove node_modules
• install with yarn (or clear npm cache)
• run your tests
