Betrachten wir als einfaches Beispiel eine Dateistruktur ähnlich der in [Größere Anwendungen](../tutorial/bigger-applications.md) und [Testen](../tutorial/testing.md):

```

Die Datei `main.py` hätte als Inhalt:

## Upgrade der FastAPI-Versionen { #upgrading-the-fastapi-versions }

Sie sollten Tests für Ihre App hinzufügen.

Mit **FastAPI** ist das sehr einfach (dank Starlette), schauen Sie sich die Dokumentation an: [Testen](../tutorial/testing.md)

Nachdem Sie Tests erstellt haben, können Sie die **FastAPI**-Version auf eine neuere Version aktualisieren und sicherstellen, dass Ihr gesamter Code ordnungsgemäß funktioniert, indem Sie Ihre Tests ausführen.

## Atualizando as versões do FastAPI { #upgrading-the-fastapi-versions }

Você deveria adicionar testes para a sua aplicação.

Com **FastAPI** isso é muito fácil (graças ao Starlette), veja a documentação: [Testes](../tutorial/testing.md)

Depois que você tiver testes, você pode atualizar a sua versão do **FastAPI** para uma mais recente e se certificar de que todo o seu código está funcionando corretamente executando seus testes.
