Question 1

How to integrate react-native-mock with Jest?

Accepted Answer

Install via 'npm i react-native-mock --save-dev', then require 'react-native-mock/mock' in a setup file like jest.config.js to mutate the cache before tests run, enabling Node.js testing.

Question 2

react-native-mock vs React Native Testing Library: which is better?

Accepted Answer

react-native-mock focuses on mocking native modules for unit tests in Node.js, while React Native Testing Library is for testing components with a more realistic rendering approach. Use react-native-mock for isolated mocking, and the Testing Library for integration-style tests.

Question 3

Does react-native-mock work with Expo projects?

Accepted Answer

It might, but since Expo abstracts native modules, compatibility could be limited; check for specific Expo module mocks or use it cautiously, as the mock is designed for standard React Native.

Question 4

What native modules are not mocked in react-native-mock?

Accepted Answer

The README doesn't list all mocks, so some newer or less common native APIs might be missing; review the source code or issues for gaps, and consider contributing if needed.

Question 5

How to handle breaking changes when updating React Native with react-native-mock?

Accepted Answer

Ensure you update to the corresponding version of react-native-mock, as it's aligned with the latest React Native API; check the GitHub releases or issues for migration guides.

Question 6

Is react-native-mock suitable for testing animations or gestures?

Accepted Answer

Likely not ideal, as animations and gestures rely heavily on native implementations; the mocks may not accurately simulate these, so consider using real simulators or specialized testing tools.
