## pytest.mark.anyio { #pytest-mark-anyio }

Se quisermos chamar funções assíncronas em nossos testes, as nossas funções de teste precisam ser assíncronas. O AnyIO oferece um plugin bem legal para isso, que nos permite especificar que algumas das nossas funções de teste precisam ser chamadas de forma assíncrona.

Sie können immer noch die meisten Funktionen in **FastAPI** mit den Kenntnissen aus dem Haupt-[Tutorial – Benutzerhandbuch](../tutorial/index.md){.internal-link target=_blank} nutzen.

Sie können diese Vorlage verwenden, um loszulegen, da sie bereits vieles der anfänglichen Einrichtung, Sicherheit, Datenbank und einige API-Endpunkte für Sie eingerichtet hat.

* Usando uma dependência você pode simplificar os testes.
* Você pode usar arquivos `.env` com ele.

JWT podría ser usado para otras cosas aparte de identificar un usuario y permitirle realizar operaciones directamente en tu API.

Por ejemplo, podrías identificar un "coche" o un "artículo de blog".

Luego, podrías agregar permisos sobre esa entidad, como "conducir" (para el coche) o "editar" (para el blog).
