Mocked Http Requests

1) Instead of using HttpClientModule, you should use HttpClientTestingModule. You will also use HttpTestingController. Below how to import and configure them: 

...
import { HttpClientTestingModule, HttpTestingController } from "@angular/common/http/testing";

describe('YourClass', () => {
 
  beforeEach(() => {
    TestBed.configureTestingModule({
      imports:
        ...
        [ AppRoutingModule, HttpClientTestingModule ]
        ...
    });
  });
  ...
});
 
2) In your test you need to get an instance of '''HttpTestingController''':
  ...
  it('should fill user data on successful login', () => {
 
    let httpMock = TestBed.get(HttpTestingController);
 
  });
