You should add tests for your app.

With **FastAPI** it's very easy (thanks to Starlette), check the docs: [Testing](../tutorial/testing.md){.internal-link target=_blank}

keeping the package name the same: `okhttp3`!

There are three kinds of compatibility we’re tracking:

## 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}
