测试时规范中未定义声明的变量 [英] Varaible declared is not defined in spec while testing

问题描述

这是我实际的AzureService

Here is my actual AzureService

declare var WindowsAzure;
declare var config;

@Injectable()
export class AzureService {
    azureUrl;
    client: any;
    programmes: Programme[];
    selectedProgramme: Programme;
    orderSummary: Order;

    constructor() {
        this.client = new WindowsAzure.MobileServiceClient(this.azureUrl);}
}

这是我的仪表板规格

describe('DashboardComponent', () => {
  beforeEach(async(() => {
    TestBed.configureTestingModule({
      declarations: [
        DashbaordComponent,
        StatusComponent
      ],
      providers:[ AzureService]
    }).compileComponents();
  }));

  it('should create the app', async(() => {
    const fixture = TestBed.createComponent(DashbaordComponent);
    const app = fixture.debugElement.componentInstance;
    expect(app).toBeTruthy();
  }));

仪表板组件承包商，我正在向其注入天蓝色服务:

Dashboard component contractor where i am injecting azure service:

constructor(private azureService: AzureService) { }

测试失败，表明我尚未定义WindowAzure，但是我应该在哪里定义?

The test is failing stating that i have not defined WindowAzure, but where am i suppose to define?

这是错误:

推荐答案

在模块级别声明变量

declare var WindowsAzure;
declare var config;
@NgModule({...})

以便它在组件，服务之间共享.

So that it is shared across the components,services.

也可以将它们导入到您用作

Also import them where ever you are using as

import { WindowsAzure } from '../azure.service.ts'
