我正在尝试按照 Angular 指南使用新的 HTTP 客户端测试服务。我收到以下错误,应为标准“匹配方法:GET,URL:http://localhost:8080/services/shift/2016-12-01”的一个匹配请求,但找不到。
我已将我的代码放在下面,不太确定我哪里出错了
单元测试
import { HttpTestingController, HttpClientTestingModule } from '@angular/common/http/testing';
import { HttpClient, HttpHandler } from '@angular/common/http';
import { TestBed } from '@angular/core/testing';
import { ShiftService } from './shift.service';
let service: ShiftService;
let backend: HttpTestingController;
describe('ShiftService', () => {
beforeEach(() => {
TestBed.configureTestingModule({
providers: [
ShiftService,
HttpClient,
HttpHandler
],
imports: [HttpClientTestingModule]
});
service = TestBed.get(ShiftService);
backend = TestBed.get(HttpTestingController);
});
afterEach(() => {
backend.verify();
});
describe('When the getShift method is invoked', () => {
it('should make a GET request to the services/shift endpoint', async() => {
service.getShift().subscribe();
backend.expectOne({
url: 'http://localhost:8080/services/shift/2016-12-01',
method: 'GET'
});
});
});
});
服务
import { HttpClient } from '@angular/common/http';
import { Injectable } from '@angular/core';
@Injectable({
providedIn: 'root'
})
export class ShiftService {
constructor(private http: HttpClient) { }
public getShift = () => {
return this.http.get('http://localhost:8080/services/shift/2016-12-01');
}
}
我已确保订阅我的 getShift() 方法并且我正在使用 HTTPTestingController。我还尝试了 HttpTestingController 的其他重载,但没有成功:/提前感谢您的帮助!
最佳答案
use describe as below
describe('When the getShift method is invoked', () => {
it('should make a GET request to the services/shift endpoint', async() => {
const path = '/testPath';
service.get(path).subscribe(response => {
expect(response).toBeTruthy();
});
const httpRequest = httpMock.expectOne(
(req: HttpRequest<any>) => req.urlWithParams === path);
// write your expect criteria here....
});
});
关于javascript - 预期有一个符合条件的请求,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/51081718/
