## Обновление версий FastAPI { #upgrading-the-fastapi-versions }

Вам следует добавить тесты для вашего приложения.

С помощью **FastAPI** это очень просто (благодаря Starlette), см. документацию: [Тестирование](../tutorial/testing.md){.internal-link target=_blank}

После создания тестов вы можете обновить свою версию **FastAPI** до более новой. После этого следует убедиться, что ваш код работает корректно, запустив тесты.
