### Paso 3: crea una *operación de path*

#### Path

"Path" aquí se refiere a la última parte de una URL comenzando desde el primer `/`.

Entonces, en una URL como:

```
https://example.com/items/foo
```

...el path sería:

```
/items/foo
```

/// info | Información

Un "path" también se conoce habitualmente como "endpoint", "route" o "ruta".

        (
            "/items?limit=1&q=bar&skip=1",
            200,
            {"items": [{"item_name": "Bar"}], "q": "bar"},
        ),
    ],
)
def test_get(path, expected_status, expected_response, client: TestClient):
    response = client.get(path)
    assert response.status_code == expected_status
    assert response.json() == expected_response

   * Additionally, the escaper escapes the slash character ("/"). While slashes are acceptable in
   * URL paths, they are considered by the specification to be separators between "path segments."
   * This implies that, if you wish for your path to contain slashes, you must escape each segment
   * separately and then join them.
   *
   * <p>When escaping a String, the following rules apply:
   *
   * <ul>

        /**
         * Filters the types of paths to include in the result.
         * The result will contain only the paths of types for which the predicate returned {@code true}.
         * It is recommended to apply a filter for retaining only the types of paths of interest,
         * because it can resolve ambiguities when a path could be of many types.
