Incluso si tu aplicación de **FastAPI** usa funciones `def` normales en lugar de `async def`, sigue siendo una aplicación `async` por debajo.

votre application **FastAPI** utilise des fonctions `def` normales au lieu de `async def`, c'est toujours une application `async` en interne.

Le `TestClient` fait un peu de magie pour appeler l'application FastAPI asynchrone depuis vos fonctions de test `def` normales, en utilisant pytest standard. Mais cette magie ne fonctionne plus lorsque nous l'utilisons dans des fonctions asynchrones. En exécutant nos tests de manière asynchrone, nous ne pouvons plus utiliser le `TestClient` dans nos fonctions...

 * Fix: Ignore null header values (for compatibility with HttpURLConnection).
 * Add URLStreamHandlerFactory support so that `URL.openConnection()` uses
   OkHttp.
 * Expose the transport ("http/1.1", "spdy/3", etc.) via magic request headers.

   `X-Android-Selected-Transport` to read the negotiated transport.
