Karma Jasmine NPM 配置

Question

业力配置错误

我正在尝试配置我的测试环境，并在尝试运行 karma 时遇到以下错误。

karma start

karma.conf.js

module.exports = function(config) {
    config.set({

        basePath: '',
        frameworks: ['jasmine'],
        files: [
            {pattern: 'node_modules/angular/*.js', included: true},
            {pattern: 'node_modules/angular-resource/*.js', included: true},
            {pattern: 'spec/*.spec.js', included: true}
        ],
        reporters: ['progress'],
        port: 9876,
        colors: true,
        logLevel: config.LOG_DEBUG,
            //config.LOG_INFO,
        autoWatch: true,
        browsers: [
            'karma-chrome-launcher',
            'karma-firefox-launcher',
            'karma-safari-launcher',
            'karma-phantomjs-launcher'
        ],
        plugins: ['karma-jasmine'],
        singleRun: false
    })
};

我在 OSX Yosemite 10.10.5 上，是的，那里有一个独立的测试“期望为真”，只是为了让它自行启动和运行。我正在编写的应用程序是 Angular，但我还没有触及任何测试。我只想让基本的测试运行器首先正常工作。

任何帮助都会很棒。谢谢。

karma 中的浏览器采用英文格式（Chrome、Firefox、PhantomJS），而不是它们各自的插件名称。只需使用npm install --save 安装插件即可。

另外：Karma 将“神奇地”加载您的node_modules 目录中以karma- 开头的任何库，因此您根本不需要在配置文件中声明plugins:。
