Question

我是karma和jasmin的整个TTD的新手，我试图在我的服务上运行测试，从我的数据库中提取数据，但我一直得到错误，说ReferenceError：找不到变量：在业力中的beforeEachProviders -test-shim.js在这里是我的测试..

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();

    });

});

});

测试RC6 littel中的API位。

例如angular2-webpack-starter中的更改。

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');
  }));

});

删除beforeEachProvider，现在使用TestBed.configureTestingModule（）你应该设置的地方提供：[]

Angular2 rc.6 Karma测试
