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。

请您参考如下方法:

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)
