Unable to test when mocking decorated component via MockComponent

[krzyhan]

Hi, Is there any workaround to deal with an error while testing with spectator & ng-mocks?

Child component has a decorator @UntilDestory() and when I use MockComponent(ChildComponent) I cannot run test. Getting error like with disabled Ivy (but Ivy is enabled). Cannot read property 'get' of undefined

Sth like this:

describe('ParentComponent', () => {
 let spectator: Spectator<ParentComponent>;

 const createComponent = createComponentFactory({
    component: ParentComponent,
    detectChanges: false,
    declarations: [MockComponent(ChildComponent)]
  });

 beforeEach(() => {
    spectator = createComponent();
  });

 test('should be created', () => {
   expect(spectator.component).toBeTruthy();
 });
});

@Component({
  selector: 'parent',
  template: '<child></child>'
})
export class ParentComponent {}

@UntilDestroy()
@Component({
  selector: 'child',
  template: 'anything'
})
export class ChildComponent {}

If I use shallow: true w/out using MockComponent() everything is working fine. Any idea?

   "@angular/common": "~9.1.11",
   "@angular/compiler": "~9.1.11",
   "@angular/core": "~9.1.11",
   "@ngneat/until-destroy": "^7.3.2",
   "@ngneat/spectator": "^5.13.1",
   "jest": "^26.4.2",
   "ng-mocks": "^10.1.2",

@krzyhan could you provide a minimal reproducible example? This error is thrown Cannot read property 'get' of undefined when Ivy is actually disabled and it can be disabled in testing environment.

I'm closing the issue. If you can reproduce it, let us know.

Sorry guys, I updated Angular & and all dependencies to the latest version and it's working fine.

Thanks for replying.
