Angular2 Jasmine spyOn http calls

Question

Http 서비스에서 올바른 엔드 포인트를 호출하는지 확인하고 싶습니다. 그렇게 할 수 있습니까?

지금까지는 내 서비스에서 테스트 한 것은 데이터를 다시 보내는 것입니다 ... 더 유용하게 만들고 싶습니다. 거의 다

import { TestBed, async, inject } from '@angular/core/testing'; 
import { SignupService } from './signup.service'; 
import { Observable } from 'rxjs/Observable'; 

import { HttpModule, Http, Response, ResponseOptions, RequestOptions, Headers, XHRBackend } from '@angular/http'; 
import { MockBackend, MockConnection } from '@angular/http/testing'; 
import { ErrorHandlerService } from '../../services/error-handler.service'; 

describe('SignupService',() => { 

    let errorStub = {}; 

    beforeEach(() => { 
    TestBed.configureTestingModule({ 
     imports: [HttpModule], 
     providers: [ 
     SignupService, 
     { provide: XHRBackend, useClass: MockBackend }, 
     { provide: ErrorHandlerService, useValue: errorStub } 
     ] 
    }); 
    }); 

    it('signup should return an application error if no apps are provided', inject([SignupService], (service: SignupService) => { 
    service.signup('', [], null).subscribe(
     suc => { }, 
     err => expect(err).toMatch(/application/) 
    ); 
    }));

    service.signup('', null, []).subscribe(
     suc => { },

     service.checkUser('').subscribe(

});

: 만약 당신이 그것을 필요로하는 경우

, 여기에 내 현재 사양 파일입니다! 그냥 mockBackend 선언 안에 기대를 추가하십시오.

예 :

mockBackend.connections.subscribe(connection => { 

     // Check if it invokes a http POST call 
     expect(connection.request.method).toBe(RequestMethod.Post); 

     // Check if the URL is correct 
     expect(connection.request.url).toBe('/some-url'); 

     connection.mockRespond(new Response(new ResponseOptions({ 
     body: JSON.stringify(''), 
     status: 200 
     }))); 

    });
