## Upgrade der FastAPI-Versionen

Sie sollten Tests für Ihre Anwendung hinzufügen.

Mit **FastAPI** ist das sehr einfach (dank Starlette), schauen Sie sich die Dokumentation an: [Testen](../tutorial/testing.md){.internal-link target=_blank}

        // This is implicitly tested by the object being constructed without errors.
        // If LsaPolicyHandle had methods called by the constructor, we would verify those calls.
