How to test a React Native component that imports a custom native module with Jest?

Question

Here is a simple component that I am trying to test using React Native 0.39 and Jest 18:

// index.ios.js

import React, { Component } from \'react\';
import { Ap         


        

Answer 1

#__mocks__/react-native-modules

const ReactNative = require('react-native')

ReactNative.NativeModules = {
  Defaults: {
    RU: {
      publicKey: '',
      privateKey: '',
    },
  },
}

module.exports = ReactNative

and then

# in test file
jest.mock('react-native-modules')
import 'react-native-modules'
