## Testing locally with Traefik

You can easily run the experiment locally with a stripped path prefix using <a href="https://docs.traefik.io/" class="external-link" target="_blank">Traefik</a>.

    And after searching for a long time for a similar framework and testing many different alternatives, APIStar was the best option available.

* **TCP doesn't know about "domains"**. Only about IP addresses.
    * The information about the **specific domain** requested goes in the **HTTP data**.
* The **HTTPS certificates** "certify" a **certain domain**, but the protocol and encryption happen at the TCP level, **before knowing** which domain is being dealt with.
* **By default**, that would mean that you can only have **one HTTPS certificate per IP address**.

### Atualizando as versões FastAPI

Você pode adicionar testes em sua aplicação.

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

Após você ter os testes, então você pode fazer o _upgrade_ da versão **FastAPI** para uma mais recente, e ter certeza que todo seu código esteja funcionando corretamente rodando seus testes.

## Cechy Pydantic

```Python hl_lines="2"
# Something goes here
def read_users(skip: int = 0, limit: int = 100):
    # Something goes here
```

## Testing Peewee with async

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

    ```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!}
```
