# Асинхронні тести { #async-tests }

Ви вже бачили, як тестувати ваші застосунки **FastAPI** за допомогою наданого `TestClient`. До цього часу ви бачили лише, як писати синхронні тести, без використання функцій `async`.

Como parte disso, eu precisava investigar, testar e usar muitas alternativas.

A história do **FastAPI** é, em grande parte, a história de seus predecessores.

Como dito na seção [Alternativas](alternatives.md):

        chain.changePasswordResult = true;

        boolean result = chain.changePassword("testuser", "newpassword123");
