Reanimated matchers for Jest in TypeScript

[hamidhadi]

I'm trying to test a component style with Jest & testing-library.
All my tests are in TS and the problem is Reanimated matchers are not supported by Jest types so this line raises an error:

expect(MyComponent).toHaveAnimatedStyle(expectedStyle); // <<  Property 'toHaveAnimatedStyle' does not exist on type 'JestMatchers<ReactTestInstance>'

I have a feeling that it must be something obvious and I'm missing something 😅 but I couldn't find anything in the doc about it.
It would be nice if someone can help me. 🙏

Did you ever figure this out? I am having the same problem.

Have you added this line to your jest-setup.js file?

require('react-native-reanimated').setUpTests();

(see docs for more details).
