### Atualizando as versões FastAPI

Você pode adicionar testes em sua aplicação.

Com o **FastAPI** é muito fácil (graças ao Starlette), verifique a documentação: [Testando](tutorial/testing.md){.internal-link target=_blank}

Após você ter os testes, então você pode fazer o _upgrade_ da versão **FastAPI** para uma mais recente, e ter certeza que todo seu código esteja funcionando corretamente rodando seus testes.
