前端vue项目添加单元测试及sonar配置

安装

npm install --save-dev jest @vue/test-utils

详情查看：https://vue-test-utils.vuejs.org/zh/

 

安装依赖：

"@vue/cli-plugin-babel": "~4.3.0",

"@vue/cli-plugin-eslint": "~4.3.0",

"@vue/cli-plugin-router": "~4.3.0",

"@vue/cli-plugin-unit-jest": "~4.3.0",

 "babel-jest": "23.6.0",

 "jest": "^26.6.3",

 "jest-sonar-reporter": "^2.0.0",

 "jest-watch-typeahead": "^0.6.1",

 

安装后查看本地文件夹：

 

 .eslintrc.js文件内容：

module.exports = {
  env: {
    jest: true
  }
}

 

setup.js文件内容：

import Vue from 'vue'
import ElementUI from 'element-ui'
Vue.use(ElementUI)

 

jest.config.js文件内容：配置jest.config.js使用https://jestjs.io/docs/configuration

module.exports = {
  moduleFileExtensions: ['js', 'jsx', 'json', 'vue'],
  transform: {
    '^.+\\.vue$': 'vue-jest',
    '.+\\.(css|styl|less|sass|scss|svg|png|jpg|ttf|woff|woff2)$':
      'jest-transform-stub',
    '.*\\.(js)$': 'babel-jest'
  },
  moduleNameMapper: {
    '^@/(.*)$': '<rootDir>/src/$1',
    '\\.(css|less)$': 'identity-obj-proxy'// 解析css文件异常处理方式
  },
  snapshotSerializers: ['jest-serializer-vue'],
  testMatch: [
    '**/tests/unit/**/*.spec.(js|jsx|ts|tsx)|**/__tests__/*.(js|jsx|ts|tsx)'
  ],
  collectCoverageFrom: [
    'src/utils/**/*.{js,vue}',
    '!src/utils/auth.js',
    '!src/utils/request.js',
    'src/components/**/*.{js,vue}',
    'src/views/**/*.{js,vue}',
    '!src/views/login/**/*.{js,vue}',
    '!src/views/iframe/**/*.{js,vue}'
  ],
  coverageDirectory: '<rootDir>/tests/unit/coverage',
  'collectCoverage': true,
  'coverageReporters': [
    'lcov',
    'text-summary'
  ],
  testURL: 'http://localhost/',
  testResultsProcessor: 'jest-sonar-reporter',
  setupFiles: ['./tests/setup.js'],
  watchPlugins: [
    'jest-watch-typeahead/filename',
    'jest-watch-typeahead/testname'
  ]
}

 

 项目根目录下新增文件sonar-project.properties，内容如下。可以将测试结果上报给sonar

#根据具体项目修改
sonar.projectKey= **查看jenkins中配置**
#根据具体项目修改
sonar.projectName=  **查看jenkins中配置**
# Source
sonar.sources=src
# Where to find tests file, also src
sonar.tests=tests
# But we get specific here
# We don't need to exclude it in sonar.sources because it is automatically taken care of
