错误：预期一个符合条件的匹配请求“按功能匹配：”，找不到

Question

我有一个userService.spec.ts文件，我想测试。代码是这样的。它调用一个调用ADMIN_API_URL的get函数。我尝试测试给定的文件，但得到了标题中提到的错误。我的user.service.spec.ts文件。

 describe('Service: User service', () => {
 let httpMock: HttpTestingController;
 let userService: UserService;
 let url: string;

  beforeEach(() => {
   TestBed.configureTestingModule({
    imports: [HttpClientTestingModule],
     providers: [
    { provide: AUTH_API_URL, useValue: 'https://auth.example.com/api/' 
      },
    { provide: SSO_API_URL, useValue: 'https://sso.example.com/auth/api/' },
    { provide: WIT_API_PROXY, useValue: 'https://wit.example.com/api/'},
    { provide: ADMIN_API_URL, useValue: 'https://admin.example.com/api/'},
    { provide: REALM, useValue: 'realm' },
    Broadcaster,
    Logger,
    AuthenticationService,
    HttpHandler,
    UserService
  ]
});
httpMock = TestBed.get(HttpTestingController);
url = TestBed.get(ADMIN_API_URL);
userService = TestBed.get(UserService);
 });

 it('Get user by user name returns valid user', (done) => {
const testUser = [{
  'attributes': {
    'fullName': 'name',
    'imageURL': '',
    'username': 'myUser'
  },
  'id': 'userId',
  'type': 'userType'
}];
userService.getUsersByName('name').subscribe((user) => {
  expect(user[1].id).toEqual('userId');
  done();
});
const req = httpMock.expectOne(request => request.method === 'GET'
&& request.url === `${url}search/users?q=name`);
req.flush({data: testUser});
 });
});

我试着测试了我心中的所有东西，但仍然无法找到我的代码有什么问题。我做了任何愚蠢的错误？

很可能URL不匹配。 expectOne条件(request.url === $ {url}搜索/用户？q = name)可能会失败。您可以记录模拟请求网址以查看实际网址是什么。

        const req = httpMock.expectOne(request => {
    console.log("url ", request.url); return true;
});
