# 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.

# 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`.

# 异步测试 { #async-tests }

您已经了解了如何使用 `TestClient` 测试 **FastAPI** 应用程序。但是到目前为止，您只了解了如何编写同步测试，而没有使用 `async` 异步函数。

在测试中能够使用异步函数可能会很有用，比如当您需要异步查询数据库的时候。想象一下，您想要测试向 FastAPI 应用程序发送请求，然后验证您的后端是否成功在数据库中写入了正确的数据，与此同时您使用了异步的数据库的库。

让我们看看如何才能实现这一点。

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

如果我们想在测试中调用异步函数，那么我们的测试函数必须是异步的。 AnyIO 为此提供了一个简洁的插件，它允许我们指定一些测试函数要异步调用。

## HTTPX { #httpx }

# Async Testler { #async-tests }

Sağlanan `TestClient` ile **FastAPI** uygulamalarınızı nasıl test edeceğinizi zaten gördünüz. Şimdiye kadar yalnızca senkron testler yazdık, yani `async` fonksiyonlar kullanmadan.
