def test_query_no_values():

Então, com uma URL assim:

```
http://localhost:8000/items/?q=foo&q=bar
```

você receberá os múltiplos *parâmetros de consulta* `q` com os valores (`foo` e `bar`) em uma lista (`list`) Python dentro da *função de operação de rota*, no *parâmetro da função* `q`.

Assim, a resposta para essa URL seria:

```JSON
{
  "q": [
    "foo",
    "bar"
  ]
}
```

        ("/items", {"x-token": "foo"}, 200, {"X-Token values": ["foo"]}),
        (
            "/items",
            [("x-token", "foo"), ("x-token", "bar")],
            200,
            {"X-Token values": ["foo", "bar"]},
        ),
    ],

    url = "/items/?q=baz&q=foobar"
    response = client.get(url)
    assert response.status_code == 200, response.text

```
http://localhost:8000/items/?q=foo&q=bar
```

vous recevriez les valeurs des multiples paramètres de requête `q` (`foo` et `bar`) dans une `list` Python au sein de votre fonction de **path operation**, dans le paramètre de fonction `q`.

Donc la réponse de cette URL serait :

```JSON
{
  "q": [
    "foo",
    "bar"
  ]
}
```
