我在使用带有 Karma 的 angular-cli 对 angular 2 应用程序进行单元测试时遇到问题，我能够让量角器在 e2e 测试中正常工作。
我运行 ng test 这就是我得到的
我在未初始化 angular-cli 的 angular2 应用程序中运行 ng test。我相信这个问题以某种方式围绕 tsconfig.json 展开。
我已经通过 ng init 使用 angular-cli 初始化了一个 angular2 应用程序，当我使用 ng test 运行该应用程序时它工作正常，我相信 tsconfig 是hammerjs 的问题，而其他 js 依赖项以某种方式干扰。
任何帮助将不胜感激。
这是我的 Karma.conf.js：
module.exports = function (config) {
config.set({
basePath: '',
frameworks: ['jasmine', 'angular-cli'],
plugins: [
require('karma-jasmine'),
require('karma-chrome-launcher'),
require('karma-remap-istanbul'),
require('angular-cli/plugins/karma')
],

{ pattern: './app/test.ts', watched: false }
],
preprocessors: {
'./app/test.ts': ['angular-cli']
},
remapIstanbulReporter: {

lcovonly: './coverage/coverage.lcov'
}
},
angularCli: {
config: '../angular-cli.json',
environment: 'dev'
},
reporters: config.angularCli && config.angularCli.codeCoverage
? ['progress', 'karma-remap-istanbul']
: ['progress'],
port: 9876,
colors: true,
logLevel: config.LOG_INFO,
autoWatch: true,
browsers: ['Chrome'],
singleRun: false
});
};这是我的 package.json
