我目前正在学习如何使用 Josh Monrony 的教程在 Ionic 2 中进行单元测试。
我在第 4 步：创建并运行单元测试。
当我运行时npm test，Chrome 会打开，但它永远不会停止加载。
然后控制台报超时：
是什么导致超时？
这是我的 karma.conf.js 文件：
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: ['jasmine', 'browserify'],
// list of files / patterns to load in the browser
files: [
'node_modules/es6-shim/es6-shim.js', // TypeError: undefined is not a constructor (evaluating 'new exports.Map()')
'node_modules/reflect-metadata/Reflect.js', // 'Uncaught reflect-metadata shim is required when using class decorators'
