Com **FastAPI** isso é muito fácil (graças ao Starlette), veja a documentação: [Testes](../tutorial/testing.md)

Depois que você tiver testes, você pode atualizar a sua versão do **FastAPI** para uma mais recente e se certificar de que todo o seu código está funcionando corretamente executando seus testes.
