/// info

Note that the `TestClient` receives data that can be converted to JSON, not Pydantic models.

If you have a Pydantic model in your test and you want to send its data to the application during testing, you can use the `jsonable_encoder` described in [JSON Compatible Encoder](encoder.md).

[XML](https://en.wikipedia.org/wiki/XML)レスポンスを返したいとしましょう。

XMLを文字列にし、`Response` に含め、それを返します。

## Response Model の仕組み { #how-a-response-model-works }

path operation で [Response Model - 戻り値の型](../tutorial/response-model.md) を宣言すると、**FastAPI** はそれを使って Pydantic によりデータをJSONにシリアライズします。

{* ../../docs_src/response_model/tutorial001_01_py310.py hl[16,21] *}

{* ../../docs_src/response_directly/tutorial002_py310.py hl[1,18] *}

## Как работает модель ответа { #how-a-response-model-works }

Когда вы объявляете [Модель ответа - возвращаемый тип](../tutorial/response-model.md) в операции пути, **FastAPI** будет использовать её для сериализации данных в JSON с помощью Pydantic.
