Эта настройка изменит цветовую тему подсветки синтаксиса:

## Изменить параметры Swagger UI по умолчанию { #change-default-swagger-ui-parameters }

import importlib

def test_main():
    test_read_main()


def test_ws():

from fastapi.testclient import TestClient

from docs_src.path_params.tutorial002_py39 import app

client = TestClient(app)


def test_get_items():
    response = client.get("/items/1")
    assert response.status_code == 200, response.text
    assert response.json() == {"item_id": 1}


def test_get_items_invalid_id():
    response = client.get("/items/item1")
    assert response.status_code == 422, response.text

{* ../../docs_src/configure_swagger_ui/tutorial002_py39.py hl[3] *}

That configuration would change the syntax highlighting color theme:

<img src="/img/tutorial/extending-openapi/image04.png">

## Change Default Swagger UI Parameters { #change-default-swagger-ui-parameters }

from fastapi.testclient import TestClient

from docs_src.response_headers.tutorial002_py39 import app

client = TestClient(app)


def test_path_operation():
    response = client.get("/headers-and-object/")
    assert response.status_code == 200, response.text
    assert response.json() == {"message": "Hello World"}

{* ../../docs_src/configure_swagger_ui/tutorial002_py39.py hl[3] *}

Esa configuración cambiaría el tema de color del resaltado de sintaxis:

## Cambiar los parámetros predeterminados de Swagger UI { #change-default-swagger-ui-parameters }

Вы можете использовать тот же `TestClient` для тестирования WebSocket.

Для этого используйте `TestClient` с менеджером контекста `with`, подключаясь к WebSocket:

{* ../../docs_src/app_testing/tutorial002_py39.py hl[27:31] *}

/// note | Примечание

Und dann können Sie Header in diesem *vorübergehenden* <abbr title="Response – Antwort: Daten, die der Server zum anfragenden Client zurücksendet">Response</abbr>-Objekt festlegen.

{* ../../docs_src/response_headers/tutorial002_py39.py hl[1, 7:8] *}

Anschließend können Sie wie gewohnt jedes gewünschte Objekt zurückgeben (ein `dict`, ein Datenbankmodell, usw.).
