### Eine *Pfadoperation* erstellen, um statische Dateien zu testen

Um nun testen zu können, ob alles funktioniert, erstellen Sie eine *Pfadoperation*:

```Python hl_lines="39-41"
{!../../../docs_src/custom_docs_ui/tutorial002.py!}
```

### Benutzeroberfläche, mit statischen Dateien, testen

# Testclient – `TestClient`

Sie können die `TestClient`-Klasse verwenden, um FastAPI-Anwendungen zu testen, ohne eine tatsächliche HTTP- und Socket-Verbindung zu erstellen, Sie kommunizieren einfach direkt mit dem FastAPI-Code.

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
```

## 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.
