AngularJS + Karma + Jasmine + Karma-Coverage：空覆盖率报告

Question

我正在尝试将我当前的 AngularJS 项目与 Karma Coverage 集成。请在 package.json 和我的 karma-config 下方找到。

Package.json

{
  "name": "Project",
  "description": "Description",
  "repository": "https://www.repo.com",
  "devDependencies": {
    "karma": "~0.10.9",
    "karma-junit-reporter": "~0.2.1",
    "karma-jasmine": "~0.1.5",
    "karma-ng-scenario": "~0.1",
    "karma-script-launcher": "~0.1.0",
    "karma-chrome-launcher": "~0.1.3",
    "karma-firefox-launcher": "~0.1.3",
    "karma-phantomjs-launcher": "~0.1.4",
    "karma-ng-html2js-preprocessor": "~0.1",
    "karma-coverage": "~0.1"
  }
}

业力配置

'use strict';

module.exports = function (config) {
  config.set({
    basePath: '../../public/',
    logLevel: config.LOG_DEBUG,
    frameworks: ['jasmine'],
    singleRun: true,
    files: [
        'libs/jquery/jquery-1.9.0.js',
        'libs/angular/1.2.10/angular.js',
        'libs/angular/**/*.js',
        'libs/angular/*.js',
        'libs/vendor/*.js',
        'libs/test/**/*.js',

        // fixtures
        {pattern: 'test/mock-data/helloworld/*.json', watched: true, served: true, included: false},

        'apps/helloworld/**/*.js',
        'apps/helloworld/*.js',
        'test/helloworld/unit/**/*.js',
        'test/helloworld/*.js',
        'views/helloworld/directives/*.html'
    ],

    exclude: [
        'libs/angular/1.2.10/*.min.js',
        'libs/angular/angular-animate.js'
    ],

    browsers: ['PhantomJS'],

    reporters: ['progress', 'junit', 'coverage'],

    preprocessor: {
        'apps/helloworld/**/*.js': ['coverage'],
        '*.html': ['ng-html2js']
    }
  })
};

当我尝试运行“node_modules/.bin/karma start conf/advisor/karma.conf.js”时，所有测试都成功运行，但业力覆盖报告完全为空。我尝试了几个选项，但无法显示报告。

控制台输出从不运行覆盖范围的预处理器。我可以看到它实际上是为 html2js 运行的。

问题：我在这里做错了吗？如何使业力覆盖以加载我的 src js 文件？

Answer 1

您缺少preprocessors 属性和coverageReporter 属性。

将此部分添加到您的 karma 配置文件中：

preprocessors: {
      'apps/helloworld/**/*.js':['coverage']
   },
coverageReporter:{
      type:'html',
      dir:'C:/Dev/coverage/'
   },

您可以将coverageReporter 输出目录更改为您想要的任何目录。

Answer 2

我能够解决问题。这是一个缺失的“s”。我的 karma 配置最初是 preprocessor，应该是 preprocessors。请在下面找到正确的业力配置：

'use strict';

  module.exports = function (config) {
  config.set({
    basePath: '../../public/',
    logLevel: config.LOG_DEBUG,
    frameworks: ['jasmine'],
    singleRun: true,
    files: [
        'libs/jquery/jquery-1.9.0.js',
        'libs/angular/1.2.10/angular.js',
        'libs/angular/**/*.js',
        'libs/angular/*.js',
        'libs/vendor/*.js',
        'libs/test/**/*.js',

        // fixtures
        {pattern: 'test/mock-data/helloworld/*.json', watched: true, served: true, included: false},

        'apps/helloworld/**/*.js',
        'apps/helloworld/*.js',
        'test/helloworld/unit/**/*.js',
        'test/helloworld/*.js',
        'views/helloworld/directives/*.html'
    ],

    exclude: [
        'libs/angular/1.2.10/*.min.js',
        'libs/angular/angular-animate.js'
    ],

    browsers: ['PhantomJS'],

    reporters: ['progress', 'junit', 'coverage'],

    preprocessors: {
        'apps/helloworld/**/*.js': ['coverage'],
        '*.html': ['ng-html2js']
    }
    })
  };

这里最有趣的一点是：它之前使用 preprocessor 为 ng-html2js 工作（我的指令测试通过了）。当我介绍覆盖率时，问题就开始发生了。
