Vue.js vuejs 中的单元测试

我正在try 为Vuejs配置/运行我的第一个单元测试.但我无法克服配置问题.我已经try 过安装这些库，但由于某些原因，我总是出错.

下面是我的代码示例:

我的目录 struct :

   hello/
     dist/
     node_modules/
     src/
      components/
        hello.vue
     test/
      setup.js
      test.spec.js
    babelrc先生
     包裹json
     webpack.config.js

我文件中的内容

src/components/hello.vue

<template> <div> {{message}} </div> </template>
<script>
export default {
  name: 'hello',
  data () { return message: 'Hi' },
  created () {
    // ...
  }
}

测试/设置.js

// setup JSDOM
require('jsdom-global')()

// make expect available globally
global.expect = require('expect')

测试/测试.斯佩克特.js

import { shallow } from 'vue/test-utils'
import  { hello} from '../../../src/components/hello.vue'

describe('hello', () => {
  // just testing simple data to see if it works
  expect(1).toBe(1)
})

babelrc先生

{
  "env": {
    "development": {
      "presets": [
        [
          "env",
          {
            "modules": false
          }
        ]
      ]
    },
    "test": {
      "presets": [
        [
          "env",
          {
            "modules": false,
            "targets": {
              "node": "current"
            }
          }
        ]
      ],
      "plugins": [
        "istanbul"
      ]
    }
  }
}

包裹json

...
  "scripts": {
    "build": "webpack -p",
    "test": "cross-env NODE_ENV=test nyc mocha-webpack --webpack-config webpack.config.js --require 测试/设置.js test/**/*.spec.js"
  },
"devDependencies": {
    "babel-core": "^6.26.0",
    "babel-loader": "^7.1.2",
    "babel-preset-env": "^1.6.1",
    "cross-env": "^5.1.1",
    "css-loader": "^0.28.7",
    "file-loader": "^1.1.5",
    "node-sass": "^4.7.2",
    "sass-loader": "^6.0.6",
    "vue-loader": "^13.5.0",
    "vue-template-compiler": "^2.5.9",
    "webpack": "^3.10.0",
    "webpack-dev-server": "^2.9.7",
    "jsdom": "^11.3.0",
    "jsdom-global": "^3.0.2",
    "mocha": "^3.5.3",
    "mocha-webpack": "^1.0.0-rc.1",
    "nyc": "^11.4.1",
    "expect": "^21.2.1",
    "@vue/test-utils": "^1.0.0-beta.12"
  },
  ...
"nyc": {
    "include": [
      "src/**/*.(js|vue)"
    ],
    "instrument": false,
    "sourceMap": false
  }

最后是我的网页包.配置.js

if(process.env.NODE_ENV == "test") {
  module.exports.externals = [ require ('webpack-node-externals')()]
  module.exports.devtool = 'inline-cheap-module-source-map'
}

现在，当我从根文件夹hello/运行npm test时，我得到了以下错误:

> hello@1.0.0 test C:\Users\john\vue-learn\hello
> npm run e2e


> hello@1.0.0 e2e C:\Users\john\vue-learn\hello
> node test/e2e/runner.js

我不知道为什么会这样.当我开始安装我的webpack项目时，我没有使用npm init命令安装测试库，因此没有冲突，但我仍然得到了这个错误:

更新(悬赏后)

我只是想测试一下我的vuejs应用程序.希望是茉莉花/因果报应.如果有人知道如何将这些集成到一个简单的应用程序中并运行firsts测试，我可以从那里开始.我的问题不是编写测试，而是配置它
