Angular2 rc.6业力测试

Question

我新来了整个TTD与karma和jasmin，我试图运行一个测试我的服务，从我的DB拉数据，但我不断得到错误说ReferenceError:找不到变量:beforeEachProviders在karma-test- shimm .js这是我的测试下面..

import { TracksServices } from './tracks.services.ts';
describe('Service: TracksServices', () => {
let service;
//setup
beforeEach(() => TestBed.configureTestingModule({
    imports: [ TracksModule, HttpModule ],
    providers: [
      TracksServices
    ],
}));
it('get 4 featured images', done => {
    service.featured(1, 4).subscribe(x => { 
      expect(x).toContain(track);
      expect(x.length).toEqual(4);
      done();
    });
});
});

在RC6中测试API有一点变化。

例如angular2-webpack-starter.

import { inject, TestBed } from '@angular/core/testing';
// Load the implementations that should be tested
import { App } from './app.component';
import { AppState } from './app.service';
describe('App', () => {
  // provide our implementations or mocks to the dependency injector
  beforeEach(() => TestBed.configureTestingModule({
    providers: [
      AppState,
      App
    ]
  }));
  it('should have a url', inject([ App ], (app: App) => {
    expect(app.url).toEqual('https://twitter.com/AngularClass');
  }));
});

beforeEachProvider被移除，现在使用TestBed.configureTestingModule()[]
