Gracias a <a href="https://www.starlette.io/testclient/" class="external-link" target="_blank">Starlette</a>, escribir pruebas para aplicaciones de **FastAPI** es fácil y agradable.

Está basado en <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>, que a su vez está diseñado basado en Requests, por lo que es muy familiar e intuitivo.

`int`가 아닌 `float`을 전달하는 경우에도 동일한 오류가 나타납니다: <a href="http://127.0.0.1:8000/items/4.2" class="external-link" target="_blank">http://127.0.0.1:8000/items/4.2</a>

/// check | 확인

즉, 파이썬 타입 선언을 하면 **FastAPI**는 데이터 검증을 합니다.

오류에는 정확히 어느 지점에서 검증을 통과하지 못했는지 명시됩니다.

이는 API와 상호 작용하는 코드를 개발하고 디버깅하는 데 매우 유용합니다.
