Bug report

Summary

react-native-permissions: NativeModule.RNPermissions is null. To fix this issue try these steps:
• If you are using CocoaPods on iOS, run `pod install` in the `ios` directory and then clean, rebuild and re-run the app. You may also need to re-open Xcode to get the new pods.
• If you are getting this error while unit testing you need to mock the native module. You can use this to get started: https://github.com/react-native-community/react-native-permissions/blob/master/mock.js
If none of these fix the issue, please open an issue on the Github repository: https://github.com/react-native-community/react-native-permissions

@yosukapro this solution solved my issue :
you need to mock react-native-permissions

import mock from 'react-native-permissions/mock';
jest.mock('react-native-permissions', () => {
    return mock;
});

@hamoudaarfaoui You need to mock the module.

See:
