// GIVEN an unknown auth type
        int unknownAuthType = -1;
        byte[] emptyToken = new byte[0];

        // WHEN parsing the auth data
        List<KerberosAuthData> result = KerberosAuthData.parse(unknownAuthType, emptyToken, mockKeys);

        // THEN the result should be an empty list
        assertNotNull(result, "The result should not be null.");

You can declare path "parameters" or "variables" with the same syntax used by Python format strings:

{* ../../docs_src/path_params/tutorial001.py hl[6:7] *}

The value of the path parameter `item_id` will be passed to your function as the argument `item_id`.

Você também pode usá-lo para gerar código automaticamente para clientes que se comunicam com sua API. Por exemplo, aplicativos front-end, móveis ou IoT.

## Recapitulando, passo a passo

### Passo 1: importe `FastAPI`

{* ../../docs_src/first_steps/tutorial001.py hl[1] *}

`FastAPI` é uma classe Python que fornece todas as funcionalidades para sua API.
