TypeError：無法讀取未定義的屬性'contextTypes'（karma + jasmine + reactRedux + webpack）

Question

我正在嘗試執行茉莉花webpack +業務背景上的react + redux測試用例。 但是得到以下錯誤

下面我添加了webpack，karma config和react + redux組件文件。

1] karma.config.js

var webpackConfig = require('./webpack.config.js'); 
module.exports = function(config) { 
    config.set({ 
     basePath: '', 
     frameworks: ['jasmine'], 
    files: [ 
     'app/assets/test/**/*Spec.js', 
     'app/assets/test/**/*Spec.jsx' 
    ], 
preprocessors: { 
    'app/assets/test/**/*Spec.js': ['webpack'], 
    'app/assets/test/**/*Spec.jsx': ['webpack'] 
}, 

webpack: webpackConfig, 
reporters: ['kjhtml'], 
port: 9876, 
colors: true, 
config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG 
logLevel: config.LOG_INFO, 
autoWatch: true, 
browsers: ['Chrome'], 
singleRun: true, 
concurrency: Infinity 

}） }

2]反應home.jsx組分

import CarouselContainer from 'containers/carouselContainer' 
import CurrentTracks from 'containers/currentTracks' 

export default class Home extends React.Component { 
    render() { 
    return (
     <div> 
     <CarouselContainer /> 
     <CurrentTracks /> 
     </div> 
    ) 
    } 
} 

3] home.Spec.jsx -

import React from 'react'; 
import { shallow } from 'enzyme'; 
import ReactTestUtils from 'react-addons-test-utils' 
import {Home} from 'pages/home' 

describe("User suite", function() { 
    const wrapper = shallow(<Home/>); 
    expect(wrapper.length).toEqual(1); 
}); 

4] Webpack.config.js -

 var path = require('path'); 
     var webpack = require('webpack');

     default: 
      config = merge(prodConfig, commonConfig); 
      break; 
     } 

     module.exports = config; 

Answer 1

它看起來像Home是一個默認的出口，因此在第4行你的天賦，你應該輸入作爲默認值。

所以行應該是

而不是

import Home from 'pages/home';

import {Home} from 'pages/home';
