### Otras formas de código asíncrono { #other-forms-of-asynchronous-code }

Este estilo de usar `async` y `await` es relativamente nuevo en el lenguaje.

# Testes Assíncronos { #async-tests }

Você já viu como testar as suas aplicações **FastAPI** utilizando o `TestClient` que é fornecido. Até agora, você viu apenas como escrever testes síncronos, sem utilizar funções `async`.

# Async Tests { #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.

# Asynchrone Tests { #async-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`-Funktionen zu verwenden.

# Tests Asíncronos { #async-tests }

Ya has visto cómo probar tus aplicaciones de **FastAPI** usando el `TestClient` proporcionado. Hasta ahora, solo has visto cómo escribir tests sincrónicos, sin usar funciones `async`.

# Асинхронное тестирование { #async-tests }

Вы уже видели как тестировать **FastAPI** приложение, используя имеющийся класс `TestClient`. К этому моменту вы видели только как писать тесты в синхронном стиле без использования `async` функций.
