```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!}
```

## 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.

from ...utils import needs_py310


@needs_py310
def test_app():
    from docs_src.app_testing.app_b_an_py310 import test_main

    test_main.test_create_existing_item()
    test_main.test_create_item()
    test_main.test_create_item_bad_token()
    test_main.test_read_nonexistent_item()
    test_main.test_read_item()

* Take a username.
* Generate a document ID from it.
* Get the document with that ID.
* Put the contents of the document in a `UserInDB` model.

Lesen Sie mehr darüber in der [FastAPI-Dokumentation über Testen](../tutorial/testing.md).

Sie können sie direkt von `fastapi.testclient` importieren:

```python
from fastapi.testclient import TestClient
```

from ...utils import needs_py310


@needs_py310
def test_app():
    from docs_src.app_testing.app_b_py310 import test_main

    test_main.test_create_existing_item()
    test_main.test_create_item()
    test_main.test_create_item_bad_token()
    test_main.test_read_nonexistent_item()
    test_main.test_read_item()

## Testing Peewee with async

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