# Asynchrone Tests

Sie haben bereits gesehen, wie Sie Ihre **FastAPI**-Anwendungen mit dem bereitgestellten `TestClient` testen. Bisher haben Sie nur gesehen, wie man synchrone Tests schreibt, ohne `async`hrone Funktionen zu verwenden.

# Async Tests

You have already seen how to test your **FastAPI** applications using the provided `TestClient`. Up to now, you have only seen how to write synchronous tests, without using `async` functions.

Vamos ver como nós podemos fazer isso funcionar.

## 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.
