Reactjs 如何对 ReactRedux 连接组件进行单元测试

我正在使用Mocha、Chai、Karma、Sinon和Webpack进行单元测试.

我按照这个链接为React Redux代码配置了测试环境.

How to implement testing + code coverage on React with Karma, Babel, and Webpack

我可以成功地测试我的action和reducers javascript代码，但在测试我的组件时，它总是会抛出一些错误.

import React from 'react';
import TestUtils from 'react/lib/ReactTestUtils'; //I like using the Test Utils, but you can just use the DOM API instead.
import chai from 'chai';
// import sinon from 'sinon';
import spies from 'chai-spies';

chai.use(spies);

let should = chai.should()
  , expect = chai.expect;

import { PhoneVerification } from '../PhoneVerification';

let fakeStore = {
      'isFetching': false,
      'usernameSettings': {
        'errors': {},
        'username': 'sahil',
        'isEditable': false
      },
      'emailSettings': {
        'email': 'test@test.com',
        'isEmailVerified': false,
        'isEditable': false
      },
      'passwordSettings': {
        'errors': {},
        'password': 'showsomestarz',
        'isEditable': false
      },
      'phoneSettings': {
        'isEditable': false,
        'errors': {},
        'otp': null,
        'isOTPSent': false,
        'isOTPReSent': false,
        'isShowMissedCallNumber': false,
        'isShowMissedCallVerificationLink': false,
        'missedCallNumber': null,
        'timeLeftToVerify': null,
        '_verifiedNumber': null,
        'timers': [],
        'phone': '',
        'isPhoneVerified': false
      }
}

function setup () {
    console.log(PhoneVerification);
    // PhoneVerification.componentDidMount = chai.spy();
    let output = TestUtils.renderIntoDocument(<PhoneVerification {...fakeStore}/>);
    return {
        output
    }
}

describe('PhoneVerificationComponent', () => {
    it('should render properly', (done) => {
        const { output } = setup();
        expect(PhoneVerification.prototype.componentDidMount).to.have.been.called;
        done();
    })
});

上面的代码会出现以下错误.

FAILED TESTS:
  PhoneVerificationComponent
    ✖ should render properly
      Chrome 48.0.2564 (Mac OS X 10.11.3)
    Error: Invariant Violation: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undefined.

我应该如何对我的React Redux连接组件(智能组件)进行单元测试？
