## Actualizando las versiones de FastAPI

Para esto es recomendable primero añadir tests a tu aplicación.

Con **FastAPI** es muy fácil (gracias a Starlette), revisa la documentación [Testing](../tutorial/testing.md){.internal-link target=_blank}

Luego de tener los tests, puedes actualizar la versión de **FastAPI** a una más reciente y asegurarte de que tu código funciona correctamente ejecutando los tests.

## Обновление версий FastAPI

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.

fastapi>=0.45.0,<0.46.0
```

"MINOR"版本中会添加breaking changes和新功能。

!!! tip
     "MINOR"是中间的数字，例如，在`0.2.3`中，MINOR版本是`2`。

## 升级FastAPI版本

你应该为你的应用程序添加测试。

使用 **FastAPI** 编写测试非常简单（感谢 Starlette），请参考文档：[测试](../tutorial/testing.md){.internal-link target=_blank}

添加测试后，你可以将 **FastAPI** 版本升级到更新版本，并通过运行测试来确保所有代码都能正常工作。

如果一切正常，或者在进行必要的更改之后，并且所有测试都通过了，那么你可以将`fastapi`固定到新的版本。

## 关于Starlette

你不应该固定`starlette`的版本。

## Testing Peewee with async

This example includes an extra *path operation* that simulates a long processing request with `time.sleep(sleep_time)`.

                actual dependency that should be called.

                This is for testing, to replace expensive dependencies with testing
                versions.

                Read more about it in the
                [FastAPI docs for Testing Dependencies with Overrides](https://fastapi.tiangolo.com/advanced/testing-dependencies/).

from ...utils import needs_py39, needs_pydanticv1


@needs_py39

def test_testing_dbs_py39(tmp_path_factory: pytest.TempPathFactory):
    tmp_path = tmp_path_factory.mktemp("data")

    os.chdir(tmp_path)
    test_db = Path("./test.db")

## Atualizando as versões do FastAPI

Você deve adicionar testes para a sua aplicação.

Com **FastAPI** isso é muito fácil (graças a Starlette), verifique a documentação: [Testing](../tutorial/testing.md){.internal-link target=\_blank}

Após a criação dos testes, você pode atualizar a sua versão do **FastAPI** para uma mais recente, execute os testes para se certificar de que todo o seu código está funcionando corretamente.

    ```Python hl_lines="16  18-20"
    {!> ../../../docs_src/settings/app02/main.py!}
    ```

### Settings and testing

Then it would be very easy to provide a different settings object during testing by creating a dependency override for `get_settings`:

```Python hl_lines="9-10  13  21"
{!../../../docs_src/settings/app02/test_main.py!}
```
