Question

我正在使用Grunt通过Karma / Jasmine运行我的单元测试，而我使用Karma进行代码覆盖，但是，代码覆盖率总是100％，因为它似乎无法找到文件，这里有一些输出：

PhantomJS 1.9.8（Mac OS X）信息：'开始测试......'

如您所见，单元测试可以找到要测试的正确文件，但代码覆盖率插件找不到相同的文件。我认为这样做的原因是我使用的是grunt-contrib-connect而不是内置的Karma Web服务器。当我使用内置的业力服务器时，单元测试也无法工作，因为他们也找不到文件。这是我的karma.conf：

module.exports = function (config) {
    config.set({
        basePath: '',

        frameworks: [ 'jasmine' ],

        files: [
            'touch/sencha-touch-all.js',
            'setup.js',
            'app.js',
            {
                pattern: 'app/**/*.js',
                watched: true,
                included: false,
                served: true
            },
            'tests/**/*.js'
        ],

        proxies: {
            '/': 'http://localhost:9000/'
        },

        preprocessors: {
            'app/**/*.js': ['coverage']
        },
        reporters: ['junit', 'progress', 'coverage'],

        coverageReporter: {
            type: 'text'
        },

        port: 9876,
        colors: true,
        logLevel: config.LOG_DEBUG,
        autoWatch: true,
        browsers: [ 'PhantomJS' ],
        captureTimeout: 60000,
        singleRun: false
    });
};

我认为grunt-contrib-connect服务器在代码覆盖率开始之前就已退出。有谁知道为什么或如何阻止它？更好的是，有没有人知道为什么内置的业力服务器将无法工作。这是当我使用内置的业力服务器时会发生的事情：

等...

您的问题可能是由于您的文件设置没有覆盖插件所期望的文件可用，因为included: false设置需要从脚本加载器（例如require.js）进行手动加载。

    files: [
        'touch/sencha-touch-all.js',
        'setup.js',
        'app.js',
        {
            pattern: 'app/**/*.js',
            watched: true,
            included: false,
            served: true
        },
        'tests/**/*.js'
    ],

尝试没有手动加载器的文件设置，让karma加载文件，看看它是否适合你。

    files: [
        'touch/sencha-touch-all.js',
        'setup.js',
        'app.js',
        'app/**/*.js',
        'tests/**/*.js'
    ],

为什么我的Karma Jasmine代码覆盖率始终为100％
