/// warning | Aviso

Antes de definir `convert_underscores` como `False`, lembre-se de que alguns proxies e servidores HTTP não permitem o uso de cabeçalhos com sublinhados.

...y tener el código para las pruebas tal como antes.

## Pruebas: ejemplo extendido

Ahora extiende este ejemplo y añade más detalles para ver cómo escribir pruebas para diferentes partes.
