/// tip | "Dica"

Observe que as funções de teste são `def` normais, não `async def`.

E as chamadas para o cliente também são chamadas normais, não usando `await`.

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

///

/// note | "Detalhes técnicos"

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

Levaria o mesmo tempo para finalizar com ou sem chamadas (concorrência) e você teria feito o mesmo tanto de trabalho.
