reactjs - Karma + Browserify + Jasmine + Istanbul + React 覆盖范围

Question

我正在尝试获取测试的覆盖率报告，但所有文件的覆盖率输出始终在一行上显示要求和文件路径。例如...

但是测试运行良好。这是一个 React 项目，因此我必须包含一些文件和预处理器的附加路径才能运行测试。

我不确定我的 karma 配置是否有问题？这就是我的配置目前的样子...

/* global module */
module.exports = function (config) {
    'use strict';
    config.set({
        autoWatch: true,
        singleRun: true,

        frameworks: ['browserify', 'jasmine'],

        files: [
            'node_modules/karma-babel-preprocessor/node_modules/babel-core/browser-polyfill.js',
            'node_modules/react/react.js',
            'src/**/*.jsx',
            'src/**/!(*spec).js'
        ],

        browsers: ['PhantomJS'],

        preprocessors: {
            'node_modules/react/react.js': ['browserify', 'sourcemap'],
            'src/**/*.jsx': ['browserify', 'sourcemap', 'coverage'],
            'src/**/!(*spec).js': ['browserify', 'sourcemap', 'coverage'],
        },

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

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

        coverageReporter: {
            instrumenters: {isparta: require('isparta')},
            instrumenter: {
                'src/**/*.js': 'isparta',
                'src/**/*.jsx': 'isparta'

            },
            reporters: [
                {
                    type: 'text-summary',
                    subdir: normalizationBrowserName
                },
                {
                    type: 'lcov',
                    subdir: normalizationBrowserName
                },
                {
                    type: 'html',
                    dir: 'coverage/',
                    subdir: normalizationBrowserName
                }
            ]
        }

    });

    function normalizationBrowserName(browser) {
        return browser.toLowerCase().split(/[ /-]/)[0];
    }

};

更新:我也使用了 commonjs 转换，并且能够让事情工作得更好一些，但测试无法运行，并且覆盖范围是转换后的代码。

确保包含覆盖范围内的所有源代码。例如，我有以下 karma.conf.js:(检查预处理器部分)

        'app/Modules/**/_*.init.js',            // Declarative functions needed for next line - Initialization Code
        'app/Modules/**/*.js',

        coverageReporter: {

        logLevel: 'LOG_DEBUG',
