En el caso de nuestra dependencia `get_settings()`, la función ni siquiera toma argumentos, por lo que siempre devuelve el mismo valor.

De esa manera, se comporta casi como si fuera solo una variable global. Pero como usa una función de dependencia, entonces podemos sobrescribirla fácilmente para las pruebas.

Você provavelmente leu anteriormente que você pode definir um [Código de Status do Retorno](../tutorial/response-status-code.md) padrão.

Porém em alguns casos você precisa retornar um código de status diferente do padrão.

## Caso de uso { #use-case }

Por exemplo, imagine que você deseja retornar um código de status HTTP de "OK" `200` por padrão.

Mas se o dado não existir, você quer criá-lo e retornar um código de status HTTP de "CREATED" `201`.
