Ele também declara novamente `id: int`. Ao fazer isso, estamos fazendo um **contrato** com os clientes da API, para que eles possam sempre esperar que o `id` estará lá e será um `int` (nunca será `None`).

#### Generar el Código del Cliente

Para generar el código del cliente puedes usar la aplicación de línea de comandos `openapi-ts` que ahora estaría instalada.

Como está instalada en el proyecto local, probablemente no podrías llamar a ese comando directamente, pero podrías ponerlo en tu archivo `package.json`.

Podría verse como esto:

```JSON  hl_lines="7"
{

    @DisplayName("Basic getters: address, hostName, inflight, sessions")
    void basicGetters() {
        assertEquals(address, transport.getRemoteAddress());
        assertNull(transport.getRemoteHostName(), "tconHostName starts null");
        assertEquals(0, transport.getInflightRequests());
        assertEquals(0, transport.getNumSessions());
    }

    @Test
    @DisplayName("isDisconnected / isFailed reflect socket and state")

            // Test odd Unicode alignment - headerStart affects alignment
            int bytesWritten = testBlock.writeString(testString, buffer, 2);

            // When even alignment (offset 2), Unicode string starts immediately
            assertTrue(bytesWritten >= 8); // "Test" in Unicode + null terminator
            // First byte should be 'T' in UTF-16LE
            assertEquals(0x54, buffer[2] & 0xFF);
        }
