Tests schreibt, ohne `async`-Funktionen zu verwenden.

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 <abbr title="Request – Anfrage: Daten, die der Client zum Server sendet">Requests</abbr> an Ihre FastAPI-Anwendung testen und dann überprüfen, ob Ihr Backend die richtigen Daten erfolgreich in die Datenbank geschrieben hat, während Sie eine asynchrone...

				if wildcard.Match("tmp-old/*", u.Object) {
					continue
				}
			}

			now := time.Now()
			if now.Sub(u.Queued) < time.Second {
				// let recently failed networks to reconnect
				// making MRF wait for 1s before retrying,
				// i.e 4 reconnect attempts.
				time.Sleep(time.Second)
			}

			// wait on timer per heal
			wait := healSleeper.Timer(context.Background())

    * Si on compare Uvicorn, il faut le comparer à d'autres serveurs d'applications comme Daphne, Hypercorn, uWSGI, etc.
* **Starlette** :
    * A les secondes meilleures performances après Uvicorn. En réalité, Starlette utilise Uvicorn. De ce fait, il ne peut qu’être plus « lent » qu'Uvicorn car il requiert l'exécution de plus de code.

Et aussi après que la `response` a été générée, avant de la renvoyer.

Par exemple, vous pourriez ajouter un en-tête personnalisé `X-Process-Time` contenant le temps en secondes nécessaire pour traiter la requête et générer une réponse :
