Con **FastAPI** es muy fácil (gracias a Starlette), revisa la documentación: [Testing](../tutorial/testing.md){.internal-link target=_blank}

Después de tener tests, puedes actualizar la versión de **FastAPI** a una más reciente, y asegurarte de que todo tu código está funcionando correctamente ejecutando tus tests.
