Die Möglichkeit, in Ihren Tests asynchrone Funktionen zu verwenden, könnte beispielsweise nützlich sein, wenn Sie Ihre Datenbank asynchron abfragen. Stellen Sie sich vor, Sie möchten das Senden von Requests an Ihre FastAPI-Anwendung testen und dann überprüfen, ob Ihr Backend die richtigen Daten erfolgreich in die Datenbank geschrieben hat, während Sie eine asynchrone Datenbankbibliothek verwenden.
