For this, you use the `TestClient` in a `with` statement, connecting to the WebSocket:

{* ../../docs_src/app_testing/tutorial002.py hl[27:31] *}

/// note

For more details, check Starlette's documentation for <a href="https://www.starlette.io/testclient/#testing-websocket-sessions" class="external-link" target="_blank">testing WebSockets</a>.

Nota que las *path operations* definen los modelos que usan para el payload de la petición y el payload del response, usando los modelos `Item` y `ResponseMessage`.

### Documentación de la API

Si vas a la documentación de la API, verás que tiene los **esquemas** para los datos que se enviarán en las peticiones y se recibirán en los responses:

<img src="/img/tutorial/generate-clients/image01.png">

| *Required*           | *Yes*                                          |

### Version

Indicates STS API version information, the only supported value is '2011-06-15'.  This value is borrowed from AWS STS API documentation for compatibility reasons.

| Params     | Value    |
| :--        | :--      |
| *Type*     | *String* |
| *Required* | *Yes*    |

### DurationSeconds

**FastAPI** is based on **OpenAPI**.

That's what makes it possible to have multiple automatic interactive documentation interfaces, code generation, etc.

OpenAPI has a way to define multiple security "schemes".

By using them, you can take advantage of all these standard-based tools, including these interactive documentation systems.

OpenAPI defines the following security schemes:

      multiple: false
      options:
        - Bug
        - Build/Install
        - Performance
        - Support
        - Feature Request
        - Documentation Feature Request
        - Documentation Bug
        - Others
    validations:
      required: true
  - type: markdown
    attributes:
      value: |

## API Request Parameters

/// note | Nota

Algunos códigos de response (ver la siguiente sección) indican que el response no tiene un body.

FastAPI sabe esto, y producirá documentación OpenAPI que establece que no hay un response body.
