Test fails due to react-native-permissions

Output: 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

Plateform: both ios and android

before installation of react-native-qrcode-scanner and react-native-permissions all tests were ok and working perfect here is my output attached the error I am facing

I have also mocked react-native-permissions in jest.setup.js file as shown below , still its not working

jest.mock('react-native-permissions', () =>
  require('react-native-permissions/mock'),
);

at time of installation i ignored ios configrations required for this pakage because i am working on ubuntu for android only

shall be thankfull for your help

I have found 2 ways to get rid of this issue

1. mock react-native-qrcode-scanner inside the test file , this is solution for single file as shown below write mock of react-native-qrcode-scanner on top of test file after imports

jest.mock('react-native-qrcode-scanner', () => jest.fn());

2. mock react-native-qrcode-scanner inside the jest.setup.js file , this is solution for all tests files as shown below write mock of react-native-qrcode-scanner inside jest.setup.js file in root dir as shown below

jest.mock(
  'react-native-qrcode-scanner/node_modules/react-native-permissions',
  () => require('react-native-permissions/mock'),
);
