Und wenn es irgendeinen anderen Stil- oder Konsistenzbedarf gibt, werde ich direkt danach fragen oder zusätzliche Commits mit den erforderlichen Änderungen hinzufügen.

### Den Code testen { #check-the-code }

* Prüfen und lesen Sie den Code, fragen Sie sich, ob er Sinn macht, **führen Sie ihn lokal aus** und testen Sie, ob er das Problem tatsächlich löst.
