Expected behavior

Test pass as before

I fixed the issue by updating my project’s jest-setup.js:

global.__reanimatedWorkletInit = () => {}
jest.mock('react-native-reanimated', () => require('react-native-reanimated/mock'))

I added this code to fix the error above. But seems there is another issue occurs: code :

    TypeError: Cannot read properties of undefined (reading 'now')

The reading 'now' issue resolved by this fix:

// add into jest.config
global.ReanimatedDataMock = {
  now: () => 0,
};

after comparing code 2.4.1 and 2.5.0. I think those 2 are bugs introduced by 2.5.0. Do we plan to have a fix?
