我是使用Karma的新手，所以我可能没有看到一些微不足道的东西。我有一个简单的测试，可以在io.js 2.4.0（Windows）上使用此设置正确运行：
karma.conf.js
// Karma configuration
// Generated on Thu Jul 23 2015 12:55:43 GMT+0200 (Hora de verano romance)
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: ['mocha', 'should'],
plugins: ['karma-mocha',
'karma-should',
'karma-chrome-launcher',
'karma-firefox-launcher'],
// list of files / patterns to load in the browser
files: [
'test/**/*.js'
],
// 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: {
},
// test results reporter to use
// possible values: 'dots', 'progress'
// available reporters: https://npmjs.org/browse/keyword/karma-reporter
reporters: ['progress'],
// 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
browsers: ['Chrome', 'Firefox'],
// Continuous Integration mode
// if true, Karma captures browsers, runs the tests and exits
singleRun: false
})
}

确定测试输出：

但是，如果我添加urlRoot: '/__karma__/',，则会收到此错误：You need to include some adapter that implements __karma__.start method!：

我需要使用urlRoot，因为我将使用代理来测试一些DOM交互。我已经搜索了这个错误，但我仍然找不到任何解决方法。
