TypeError: Cannot read property 'bundleId' of undefined when running Jest tests

Geetting the following error when running jest tests:

Error:

TypeError: Cannot read property 'bundleId' of undefined

Code:

import DeviceInfo from 'react-native-device-info'
const bundleId = DeviceInfo.getBundleId()

package.json:

"react": "~15.4.1",
"react-native": "^0.38.1"

Just mock the method you’re using @zhen639 @arunshan

jest.mock('react-native-device-info', () => {
  return {
    getUniqueID: jest.fn()
  }
})

The solution provided by @carloscuesta worked for me.

package.json:

  "jest": {
    "setupFiles": [
      "./testenv.js"
    ],
    // ...

testenv.js:

jest.mock('react-native-device-info', () => {
  return {
    getModel: jest.fn(),
  };
});
