Aquí veremos un ejemplo usando <a href="https://sqlmodel.tiangolo.com/" class="external-link" target="_blank">SQLModel</a>.

For example:

* <a href="https://www.jetbrains.com/help/pycharm/creating-virtual-environment.html" class="external-link" target="_blank">PyCharm</a>

/// tip

You normally have to do this only **once**, when you create the virtual environment.

`TestClient`는 <a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a>를 기반으로 하고 있으며, 다행히 이를 직접 사용하여 API를 테스트할 수 있습니다.

## 예시

간단한 예시를 위해 [더 큰 어플리케이션 만들기](../ko/tutorial/bigger-applications.md){.internal-link target=_blank} 와 [테스트](../ko/tutorial/testing.md){.internal-link target=_blank}:에서 다룬 파일 구조와 비슷한 형태를 확인해봅시다:

```

`TestClient` ⚓️ 🔛 <a href="https://www.python-httpx.org" class="external-link" target="_blank">🇸🇲</a>, &amp; ↩️, 👥 💪 ⚙️ ⚫️ 🔗 💯 🛠️.

href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers" class="external-link" target="_blank">‘X-’ 접두어를 사용하여</a> 커스텀 사설 헤더를 추가할 수 있습니다.

하지만, 여러분이 브라우저에서 클라이언트가 볼 수 있기를 원하는 커스텀 헤더가 있는 경우, CORS 설정에 이를 추가해야 합니다([CORS (Cross-Origin Resource Sharing)](../tutorial/cors.md){.internal-link target=_blank}에서 자세히 알아보세요). `expose_headers` 매개변수를 사용하여 <a href="https://www.starlette.io/middleware/#corsmiddleware" class="external-link" target="_blank">Starlette의 CORS 설명서</a>에 문서화된 대로 설정할 수 있습니다....

`status_code` también puede recibir un `IntEnum`, como por ejemplo el <a href="https://docs.python.org/3/library/http.html#http.HTTPStatus" class="external-link" target="_blank">`http.HTTPStatus`</a> de Python.

Esto hará:

* Devolver ese código de estado en el response.
* Documentarlo como tal en el esquema de OpenAPI (y por lo tanto, en las interfaces de usuario):

Zum Beispiel bietet **FastAPI** selbst eine alternative API-Dokumentation (verwendet ReDoc), welche Sie unter <a href="http://127.0.0.1:8000/redoc" class="external-link" target="_blank">http://127.0.0.1:8000/redoc</a> einsehen können:
