流星/用酶反应摩卡测试-找不到模块'has‘

Question

如前所述，我正在使用React运行Meteor应用程序，并开始用Mocha编写测试。目前，我有一个基本的测试，测试什么都没有。

client/prospects/ProspectForm.tests.jsx

import React from 'react';
import { shallow } from 'enzyme';

describe('<Foo />', () => {

  it('calls componentDidMount', () => {
  });

});

当我启动我的测试服务器时，我得到以下错误

​

​

找不到模块'has‘。看起来问题源于酶，但当我创建一个新的流星应用程序，添加酶和实际流星:摩卡，然后添加同样的测试，它的工作很好，所以它必须与我的环境在这个应用程序。

这是我的package.json

    {
  "name": "myApp",
  "private": true,
  "scripts": {
    "start": "meteor run"
  },
  "dependencies": {
    "material-ui": "^0.15.0",

}

这是我的流星包文件

有人知道这是怎么回事吗？

Answer 1

如果您还没有安装这两个依赖项，则还需要安装它们：

npm i --save-dev react-addons-test-utils
npm i --save-dev react-dom

看起来你有反应，但你错过了测试用例。

运行流星更新为我解决了这一问题，我也不得不照达文所说的去做。
