## Testando: exemplo estendido

Agora vamos estender este exemplo e adicionar mais detalhes para ver como testar diferentes partes.

### Arquivo de aplicativo **FastAPI** estendido

Vamos continuar com a mesma estrutura de arquivo de antes:

## Déprécier des paramètres

Disons que vous ne vouliez plus utiliser ce paramètre désormais.

Il faut qu'il continue à exister pendant un certain temps car vos clients l'utilisent, mais vous voulez que la documentation mentionne clairement que ce paramètre est <abbr title="obsolète, recommandé de ne pas l'utiliser">déprécié</abbr>.
