I have used MockComponent(FormComponent) inside spec.ts

describe('editing point', () => {
    const createComponent = createComponentFactory({
      component: PointDialogComponent,
      imports: [MockComponent(PointFormComponent)],
    });

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

    it('should create', () => expect(spectator.component).toBeTruthy());
  });

So when I run this test I got error:

PointDialogComponent › editing point › should create
TypeError: Cannot read properties of undefined (reading ‘length’)

I figured out it is thrown when I added this line: PointAction = PointAction; to PointFormComponent

export enum PointAction {
  CREATE,
  EDIT,
}

Any solution for this? I can’t figured out why I keep getting this error.
