Question

测试期间出现错误消息：

Error: StaticInjectorError(DynamicTestModule)[AuthService -> Http]: 
  StaticInjectorError(Platform: core)[AuthService -> Http]: 
    NullInjectorError: No provider for Http!

我的脚本 auth.service.spec.ts ：

describe('AuthService', () => {
  let injector: TestBed;
  let service: AuthService;
  let httpMock: HttpTestingController;

  beforeEach(() => {
    TestBed.configureTestingModule({
      imports: [HttpClientTestingModule, RouterTestingModule] ,
      providers: [AuthService]
    });
    injector = getTestBed();
    service = injector.get(AuthService);
    httpMock = injector.get(HttpTestingController);
  });

  it('should be created', inject([AuthService], (service: AuthService) => {
    expect(service).toBeTruthy();
  }));
});

将HttpClientTestingModule类添加到导入无济于事。我该怎么做才能解决测试中的错误？

错误：StaticInjectorError（DynamicTestModule）[AuthService - ＆gt; HTTP]：
