Sie könnten das auf der obersten Ebene des Moduls/der Datei machen, aber das würde auch bedeuten, dass **das Modell geladen wird**, selbst wenn Sie nur einen einfachen automatisierten Test ausführen, dann wäre dieser Test **langsam**, weil er warten müsste, bis das Modell geladen ist, bevor er einen davon unabhängigen Teil des Codes ausführen könnte.

### Est-ce que la concurrence est mieux que le parallélisme ?

Nope ! C'est ça la morale de l'histoire.
