How to unit test this effect (with {dispatch: false})?

Question

ngrx and unit testing beginner here. I have the following effect:

@Injectable()
export class NotificationEffects {
  @Effe         


        

Answer 1

So it's as simple as this:

describe('notificationShow$', () => {
  let effects: NotificationEffects;
  let service: any;
  let actions$: Observable;
  const payload = {test: 123};

  beforeEach( () => {
    TestBed.configureTestingModule( {
      providers: [
        NotificationEffects,
        provideMockActions( () => actions$ ),
        {
          provide: NotificationService,
          useValue: jasmine.createSpyObj('NotificationService', ['info'])
        }
      ]
    } );

    effects = TestBed.get(NotificationEffects);
    service = TestBed.get(NotificationService);
  });

  it('should call a notification service method info with a payload', () => {
    actions$ = cold('a', { a: new notificationAction.NotificationShowAction(payload) });
    effects.notificationShow$.subscribe(() => {
      expect(service.info).toHaveBeenCalledWith(payload);
    });
  });
});
