我是使用 Jasmine/Karma 进行角度测试的新手，我在使用 HttpTestingController 测试角度服务时遇到了一个问题。这是源代码的一部分：

getProfile(userName: string) {
    let config = {
      params: {
        user_id: "test"    
      }
    }
    return this.http
      .get(`https://api.github.com/users/${userName}`, config);
  }

使用 HttpTestingController 的 expectOne 调用服务时：

it('should add an Authorization header', () => {
let response;
userService.getProfile('blacksonic').subscribe(response => {
  expect(response).toBeTruthy();
});


const req = 
httpMock.expectOne({ method: 'GET', url:'https://api.github.com/users/blacksonic' });

});

我收到以下错误：

Error: Expected one matching request for criteria "Match method: GET, URL: https://api.github.com/users/blacksonic", found none.
