Bug: cannot .replace() a component that has an abstract base class

[Eugeny]

ng-mocks is checking the decorators and will fail if there's both @Component and @Injectable present. Instead, it should ignore @Injectable if there's @Component or @Directive present.

@Injectable is required on base component classes to avoid the Class is using Angular features error when inheriting, for example:

@Injectable()
abstract class Base {
	ngOnInit () {} 
}

@Component({...})
class Component extends Base {}

Why do you need Base to be Injectable as you can't inject it directly ? 🤔

I have a similar architecture, so I can purpose another way if you can adapt your code:

@Component({
  selector: 'app-base',
  template: '',
  standalone: true,
  changeDetection: ChangeDetectionStrategy.OnPush,
})
export abstract class Base {

It's a base class for both components and directives

What about an abstract directive then ?

@Directive({
  standalone: true,
})
export abstract class Base {
