HOC as a function won't get generated docs

Similar to #177 but a slightly different scenario...

Given a HOC method like so:

import { bool } from 'prop-types';

const withSomeExtraProps = Wrapped => {
  class HigherOrderComponent extends Component  {
    static propTypes = Object.assign({}, Wrapped.propTypes, {
      /**
       * This should be picked up in the docgenInfo
       */
      anExtraProp: bool,
    });
    static defaultProps = Object.assign({}, Wrapped.defaultProps, {
      anExtraProp: false,
    });
    // ....the rest of the HOC logic
  }
  return HigherOrderComponent;
}

export default withSomeExtraProps;

I understand that this wouldn't automatically mean that the export default withSomeExtraProps(Wrapped) wouldn't automatically get the docgenInfo from the HOC added, but I thought individually this HOC would have it's own docgenInfo that I could reference on it's own.

However, it seems the inner component class here doesn't get recognised and parsed. Does the component class need to be exported for the parser to find it?

Commencez par reproduire l’exemple de HOC présent dans l’issue et suivez la manière dont le parser traite la classe du composant interne. Confirmez le comportement attendu de docgenInfo et ajoutez une couverture montrant que la prop supplémentaire du HOC est reconnue ; le rapport ne mentionne aucun fichier ni test existant.
