第一:我知道Angular2处于alpha状态且经常变化.

我正在使用Angular2.有一个带有http依赖的注入服务,我想使用模拟后端进行测试.应用程序启动时该服务正常工作,但我没有运气编写测试并让模拟后端响应.任何见解,在我缺少的测试设置或实现中是否有明显的东西？

} from 'angular2/test';
import { MockBackend, MockConnection, BaseRequestOptions, Http, Response } from 'angular2/http';
import { Injector, bind } from 'angular2/angular2';
import { ObservableWrapper } from 'angular2/src/core/facade/async'
