Varaible宣佈在測試

Question

這裏就不在規範中定義爲我的實際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);} 
} 

這裏是我的儀表板規格

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(); 
    })); 

儀表板組件承包商我在哪裏注射湛藍服務：

constructor(private azureService: AzureService) { } 

測試失敗，說明我沒有定義WindowAzure，但我在哪裏設想界定？

這裏是錯誤：

Answer 1

在模塊級聲明變量

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

所以它是跨組件共享，服務。

而且導入它們在任何你正在使用的

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