Jest, React native и asyn c -хранилище: инвариантное нарушение: собственный модуль не может быть нулевым

Запустить с Android

Все пакеты были успешно связаны.

Я попытался 

$ ./gradlew clean #in android folder

$ react-native start

$ react-native run-android

, затем выдайте сообщение об ошибке

Нарушение инварианта: Нативный модуль не может быть нулевым 

$ jest
 FAIL  __tests__/SignInScreen-test.js
  ● Test suite failed to run

    Invariant Violation: Native module cannot be null.

  console.log node_modules/redux-logger/dist/redux-logger.js:1
       prev state {
      authReducer: {
...

Как можно исправить эту ошибку или есть решения для тестирования собственного приложения React, например Jest?

jestSetupFile. js

import mockAsyncStorage from '@react-native-community/async-storage/jest/async-storage-mock';

jest.mock('@react-native-community/async-storage', () => mockAsyncStorage);

jest.mock('react-native-keychain', () => ({
  SECURITY_LEVEL_ANY: 'MOCK_SECURITY_LEVEL_ANY',
  SECURITY_LEVEL_SECURE_SOFTWARE: 'MOCK_SECURITY_LEVEL_SECURE_SOFTWARE',
  SECURITY_LEVEL_SECURE_HARDWARE: 'MOCK_SECURITY_LEVEL_SECURE_HARDWARE',
  setGenericPassword: jest.fn().mockResolvedValue(),
  getGenericPassword: jest.fn().mockResolvedValue(),
  resetGenericPassword: jest.fn().mockResolvedValue(),
}));

SignInScreen-тест. js

import {SignInScreen} from '../screens/SignInScreen';

describe('Test Component using hooks', () => {
  test('SignInScreen', () => {
    expect(<SignInScreen />).toMatchSnapshot();
  });
});
