ngOnInit() {
  if (this.session.getToken()) {
    this.isUserLogged = true;
  }

  this.loadingObserver = this.session.loadingObservable.subscribe(loading => this.isLoading = loading);
}

我的测试如下

it('Testing ngOnInit() ...',async(() => {
  let spy = spyOn(services.session,'getToken').and.returnValue('token');
  services.session.loadingObservable.subscribe(any => expect(component.isLoading).toEqual(false));
  component.ngOnInit();
  expect(component.isUserLogged).toEqual(true);
  expect(spy).toHaveBeenCalled();
}));

但在我的应用程序的代码覆盖范围内,订阅不包括在内.事实上,期待虚假也有效.

您对如何测试订阅有任何想法吗？
