Testing with Jest
Worklets code currently can't be tested in Jest directly. Instead you have to use its mock implementation.
Setup
If you already have Jest tests set up for Reanimated, no additional setup is required.
TypeScript
If you have Jest configured to run TypeScript files, add the following code to your setup file:
jest.mock('react-native-worklets', () =>
require('react-native-worklets/src/mock')
);
JavaScript
For JavaScript files, add the following code to your setup file:
jest.mock('react-native-worklets', () =>
require('react-native-worklets/lib/module/mock')
);
