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).

///

## Run it { #run-it }

After that, you just need to install `pytest`.

[응답 모델](../tutorial/response-model.md)을 선언하면 FastAPI는 Pydantic을 사용해 데이터를 JSON으로 직렬화합니다.

응답 모델을 선언하지 않으면, FastAPI는 [JSON 호환 가능 인코더](../tutorial/encoder.md)에 설명된 `jsonable_encoder`를 사용해 데이터를 변환하고 이를 `JSONResponse`에 넣습니다.

또한 `JSONResponse`를 직접 생성해 반환할 수도 있습니다.

/// tip | 팁

当你创建一个 **FastAPI** *路径操作* 时，你可以正常返回以下任意一种数据：`dict`，`list`，Pydantic 模型，数据库模型等等。

如果你声明了 [响应模型](../tutorial/response-model.md)，FastAPI 会使用它通过 Pydantic 将数据序列化为 JSON。

如果你没有声明响应模型，**FastAPI** 会使用在 [JSON 兼容编码器](../tutorial/encoder.md) 中阐述的 `jsonable_encoder`。
然后，**FastAPI** 会在后台将这些兼容 JSON 的数据（比如字典）放到一个 `JSONResponse` 中，该 `JSONResponse` 会用来发送响应给客户端。

但是你可以在你的 *路径操作* 中直接返回一个 `JSONResponse`。
