… et avoir le code des tests comme précédemment.

## Tester : exemple étendu { #testing-extended-example }

Étendons maintenant cet exemple et ajoutons plus de détails pour voir comment tester différentes parties.

### Fichier d’application **FastAPI** étendu { #extended-fastapi-app-file }

Continuons avec la même structure de fichiers qu’auparavant :

```
.
├── app
│   ├── __init__.py

	// Update part info if it already exists.
	for i, part := range fi.Parts {
		if partNumber == part.Number {
			fi.Parts[i] = partInfo
			return
		}
	}

	// Proceed to include new part info.
	fi.Parts = append(fi.Parts, partInfo)

	// Parts in FileInfo should be in sorted order by part number.

* For HTTPS, **the server** needs to **have "certificates"** generated by a **third party**.
    * Those certificates are actually **acquired** from the third party, not "generated".
* Certificates have a **lifetime**.
    * They **expire**.
    * And then they need to be **renewed**, **acquired again** from the third party.
* The encryption of the connection happens at the **TCP level**.
    * That's one layer **below HTTP**.

/// note | Nota

Ten en cuenta que debes devolver el `JSONResponse` directamente.

///

/// info | Información

La clave `model` no es parte de OpenAPI.

**FastAPI** tomará el modelo de Pydantic de allí, generará el JSON Schema y lo colocará en el lugar correcto.

El lugar correcto es:

            map.put(parser.getName(), parse(parser, toType));
        }
        return map;
    }

    /**
     * Parses a sequence of XML elements and converts them to the appropriate {@link Collection} type.
     *
     * @param parser The XML parser
     * @return Converted Collection instance
     */

/**
 * Reads a stream of [RFC 2046][rfc_2046] multipart body parts. Callers read parts one-at-a-time
 * until [nextPart] returns null. After calling [nextPart] any preceding parts should not be read.

 * ```kotlin

Asegúrate de [Actualizar la versión de FastAPI](../deployment/versions.md#upgrading-the-fastapi-versions) a al menos 0.95.1 antes de usar `Annotated`.
