Esto te permite usar `pytest` directamente sin complicaciones.

///

/// note | Nota Técnica

También podrías usar `from starlette.testclient import TestClient`.

**FastAPI** proporciona el mismo `starlette.testclient` como `fastapi.testclient` solo por conveniencia para ti, el desarrollador. Pero proviene directamente de Starlette.

///

/// tip | Consejo

Это позволяет вам использовать `pytest` без лишних усложнений.

///

/// note | Технические детали

Также можно написать `from starlette.testclient import TestClient`.

**FastAPI** предоставляет тот же самый `starlette.testclient` как `fastapi.testclient`. Это всего лишь небольшое удобство для Вас, как разработчика. Но он берётся напрямую из Starlette.
