Jest: Impor Uji Snapshot tidak berfungsi dengan babel-preset

Saya mencoba tes snapshot sederhana. Komponen yang saya uji menggunakan komponen lain dari sebuah modul. Tes gagal saat mencoba mengimpor modul yang tidak di-mock ini dengan:

Kegagalan

Using Jest CLI v14.1.0, jasmine2, babel-jest, jest-react-native preset
 FAIL  js/app/SetupView/__tests__/SetupView-test.js (0s)

Tes

'use strict';
import 'react-native';
import React from 'react';

import SetupView from '../index';

import renderer from 'react-test-renderer';

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

SetupView Komponen

'use strict';

import React from 'react';
import {
  View,
  Text,
  TouchableHighlight,
  Image,
  Animated,
} from 'react-native';

import DataContainer from 'react.datacontainer'; //<---fails here
import DashboardSettings from './DashboardSettings';
.
.
.

package.json

"jest": {
    "globals": {
      "__DEV__": true
    },
    "collectCoverage": false,
    "verbose": true,
    "preset": "jest-react-native",
    "modulePathIgnorePatterns": [
      "node_modules/react-native/node_modules/yeoman-generator",
      "node_modules/react-native/node_modules/fbjs"
    ],
    "unmockedModulePathPatterns": [
      "react.datacontainer",
      "react.data",
      "react.base.theme",
      "react.layout"
    ]
  }

FYI, saya memiliki file .babelrc di direktori root saya yang menunjuk ke preset asli-reaksi dan pengujian berjalan tetapi gagal jika saya mengomentari baris 12 karena DataContainer tidak ditentukan.
