Karma Unit test cases not working with CustomDynamicNodeComponent

[arun007sivan]

While writing unit test case for Angular 18 component which extends CustomDynamicNodeComponent , its throwing NullInjectorError even after providing mock ComponentEventBusService. How can we resolve this issue ?

[arun007sivan]

describe('TargetComponent', () => {
  let component: TargetComponent;
  let fixture: ComponentFixture<TargetComponent>;
  let componentEventBusService: jasmine.SpyObj<MockComponentEventBusService>;
  beforeEach(async () => {
    await TestBed.configureTestingModule({
      imports: [BrowserAnimationsModule, VflowModule],
      providers: [
        {
          provide: ActivatedRoute,
          useValue: {},
        },
        {
          provide: 'ComponentEventBusService',
          useClass: MockComponentEventBusService,
        },
        provideHttpClient(withInterceptorsFromDi()),
        provideHttpClientTesting(),
      ],
    }).compileComponents();

    fixture = TestBed.createComponent(TargetComponent);
    component = fixture.componentInstance;
    fixture.detectChanges();
  });
  it('should create', () => {
    expect(component).toBeTruthy();
  });
});

adding test case here.

Hi! I'll see how to fix this during the next month

[artem-mangilev]

Decided to make that service as optional dependency, so you don't need to pass it to providers. Also wrote similar test to make sure CustomDynamicNodeComponent and CustomNodeComponent works without providers: cd129f6

I will release this during October.

UPD: published a pre-minor 0.13.0-0, so you may check here

[arun007sivan]

Ok thanks for the quick response, i will check & revert back.

[artem-mangilev]

I released 0.13 with the fix, did you manage to check if this DI error disappear?

[arun007sivan]

Now its expecting HandleService

[artem-mangilev]

Sorry, will be fixed in 0.14.2

UPD: in 0.15.0 as I already started doing this version
