When running with Jest, I get the above error message.

If you are getting this error while unit testing you need to mock the native module. Follow the guide in the README. However, there is no instruction in the README.

This issue is very similar to #368, and I have tried all the answers but it couldn't help.

Steps To Reproduce

yarn test

Reproducible sample code

__tests__/App.test.js

import React from 'react';
import App from '../app/src/App';

import renderer from 'react-test-renderer';

test('renders correctly', () => {
  const tree = renderer.create(<App />).toJSON();
  expect(tree).toMatchSnapshot();
});

__mocks__/react-native-permission.js (Copy from mock.js in repo)

/* eslint-disable no-undef */

const {PERMISSIONS, RESULTS} = require('react-native-permissions/lib/commonjs/constants');
export {PERMISSIONS, RESULTS};

export const openSettings = jest.fn(async () => {});
export const check = jest.fn(async permission => RESULTS.GRANTED);
export const request = jest.fn(async permission => RESULTS.GRANTED);

const notificationOptions = [
  'alert',
  'badge',
  'sound',
  'criticalAlert',
  'carPlay',
  // 'provisional', // excluded as it's not included in NotificationSettings
];

const notificationSettings = {
  alert: true,
  badge: true,
  sound: true,
  carPlay: true,
  criticalAlert: true,
  lockScreen: true,
  notificationCenter: true,
};

export const checkNotifications = jest.fn(async () => ({
  status: RESULTS.GRANTED,
  settings: notificationSettings,
}));

export const requestNotifications = jest.fn(async options => ({
  status: RESULTS.GRANTED,
  settings: options
    .filter(option => notificationOptions.includes(option))
    .reduce((acc, option) => ({...acc, [option]: true}), {
      lockScreen: true,
      notificationCenter: true,
    }),
}));

export default {
  PERMISSIONS,
  RESULTS,
  openSettings,
  check,
  request,
  checkNotifications,
  requestNotifications,
};

jest.config.js

module.exports = {
  preset: 'react-native',
  transformIgnorePatterns: ['node_modules/(?!((jest-)?react-native|react-navigation|@react-navigation/.*))'],
};

Any solution?
I'm glad to share any further information if you need.
