# 테스팅

<a href="https://www.starlette.dev/testclient/" class="external-link" target="_blank">Starlette</a> 덕분에 **FastAPI** 를 테스트하는 일은 쉽고 즐거운 일이 되었습니다.

Starlette는 <a href="https://www.python-httpx.org\" class="external-link" target="_blank">HTTPX</a>를 기반으로 하며, 이는 Requests를 기반으로 설계되었기 때문에 매우 친숙하고 직관적입니다.

이를 사용하면 FastAPI에서 <a href="https://docs.pytest.org/" class="external-link" target="_blank">pytest</a>를 직접 사용할 수 있습니다.
