// preprocess matching files before serving them to the browser // available preprocessors: https://npmjs.org/browse/keyword/karma-preprocessor preprocessors: { '../TestFiles/test.js':'coverage' }, // test results reporter to use // possible values: 'dots', 'progress' // available reporters: https://npmjs.org/browse/keyword/karma-reporter reporters: ['progress','coverage'], coverageReporter:{ type:'html', dir:'../TestFiles/coverage/' },
变动如下：
在reporters中增加coverage
preprocessors中指定js文件
添加coverageReporter节点，将覆盖率报告类型type设置为html，输入目录dir指定到你希望的目录中
此时完整的karma.conf.js如下：
// Karma configuration // Generated on Fri May 29 2015 19:30:26 GMT+0800 (中国标准时间) module.exports = function(config) { config.set({ // base path that will be used to resolve all patterns (eg. files, exclude) basePath: '', // frameworks to use // available frameworks: https://npmjs.org/browse/keyword/karma-adapter frameworks: ['jasmine'], // list of files / patterns to load in the browser files: [ '../TestFiles/jasmineTest.js', '../TestFiles/test.js' ], // list of files to exclude exclude: [ ], // preprocess matching files before serving them to the browser // available preprocessors: https://npmjs.org/browse/keyword/karma-preprocessor preprocessors: { '../TestFiles/test.js':'coverage' }, // test results reporter to use // possible values: 'dots', 'progress' // available reporters: https://npmjs.org/browse/keyword/karma-reporter reporters: ['progress','coverage'], coverageReporter:{ type:'html', dir:'../TestFiles/coverage/' }, // web server port port: 9876, // enable / disable colors in the output (reporters and logs) colors: true, // level of logging // possible values: config.LOG_DISABLE || config.LOG_ERROR || config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG logLevel: config.LOG_INFO, // enable / disable watching file and executing tests whenever any file changes autoWatch: true, // start these browsers // available browser launchers: https://npmjs.org/browse/keyword/karma-launcher browsers: ['Chrome'], // Continuous Integration mode // if true, Karma captures browsers, runs the tests and exits singleRun: false }); };
执行命令：
复制代码 代码如下:
karma start karma.conf.js
图17（执行命令后，在配置文件coverageReporter节点中指定的dir中，我们将找到生成的覆盖率报告，karma-coverage还生成了一层子文件夹，对应于执行测试的浏览器+版本号+操作系统版本）：
