Isso permite que você use `pytest` diretamente sem complicações.

/// note | "Detalhes técnicos"

Você também pode usar `from starlette.testclient import TestClient`.

**FastAPI** fornece o mesmo `starlette.testclient` que `fastapi.testclient` apenas como uma conveniência para você, o desenvolvedor. Mas ele vem diretamente da Starlette.
