Unittesting - How to test inherited and not ng2-smart-table components?

```@Component({
selector: 'ui-select-list',
template: `


{{ option.title }}

`
})
export class SelectListComponent extends DefaultEditor implements OnInit {
@Input() placeholder: string;
@Input() selectedItem;
@Input() rowData: any[];
@Output() itemSelect = new EventEmitter();

constructor() {
super();
}

ngOnInit(): void {
}

updateSelected($event) {
this.itemSelect.emit($event);
}
}
```

How do I testing it?
