Na sobrescrita da dependência, definimos um novo valor para `admin_email` quando instanciamos um novo objeto `Settings`, e então retornamos esse novo objeto.

Após isso, podemos testar se o valor está sendo utilizado.

## Lendo um arquivo `.env`

Se você tiver muitas configurações que variem bastante, talvez em ambientes distintos, pode ser útil colocá-las em um arquivo e depois lê-las como se fossem variáveis de ambiente.

      // This guarantees a deterministic sequence when handling the canceled request:
      // 1. Server reads request and dequeues first response
      // 2. Client cancels request
      // 3. Server tries to send response on the canceled stream
      // Otherwise, there is no guarantee for the sequence. For example, the server may use the
      // first mocked response to respond to the second request.
