找到一种获得业力覆盖率报告的好方法？

Question

我正在使用 karma-coverage + browserify + angular。我从覆盖中得到的结果是 100% 的被测文件都被覆盖了，这是不正确的。知道如何完成这项工作吗？

这是我的文件 karma.conf.js ：

// Karma configuration

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: ['browserify', 'jasmine'],

        // list of files / patterns to load in the browser
        files: [
            'karma.spec.js',
            'node_modules/es6-shim/es6-shim.js',
            'src/**/*.js',
            'unitest/**/*.js',
            'node_modules/karma-read-json/karma-read-json.js',
            { pattern: 'unitest/mocks/*.json', included: false }
        ],

        // 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: {
            'karma.spec.js': ['browserify'],
            'src/**/*.js': ['browserify']
        },

        browserify: {
            debug: true,
            transform: ['babelify']
        },

        // test results reporter to use
        // possible values: 'dots', 'progress'
        // available reporters: https://npmjs.org/browse/keyword/karma-reporter
        // https://www.npmjs.com/package/karma-notify-reporter
        // enable coverage module
        reporters: ['progress', 'coverage'],

        // generate coverage report in htm format
        coverageReporter: {
            type : 'json',
            dir : 'report/',
            subdir: './report',
            file: 'coverage-final.json'
        },
        // 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
        // Start these browsers, currently available:
        // - Chrome
        // - ChromeCanary
        // - Firefox
        // - Opera
        // - Safari (only Mac)
        // - PhantomJS
        // - IE (only Windows)
        browsers: ['Chrome', 'PhantomJS'],

        // If browser does not capture in given timeout [ms], kill it
        'captureTimeout': 60000,

        // Continuous Integration mode
        // if true, Karma captures browsers, runs the tests and exits
        singleRun: true,

        // Concurrency level
        // how many browser should be started simultaneous
        concurrency: Infinity
    })
}

感谢大家，我找到了正确的解决方案。

这是我的文件 Karma.conf 和 package.json ：

Karma.conf：
