It's very common in Python packages to try the best to **avoid breaking changes** in **new versions**, but it's better to be safe, and install newer versions intentionally and when you can run the tests to check everything is working correctly.

Avec **FastAPI** c'est très facile (merci à Starlette), consultez la documentation : [Testing](../tutorial/testing.md){.internal-link target=_blank}

Après avoir effectué des tests, vous pouvez mettre à jour la version **FastAPI** vers une version plus récente, et vous assurer que tout votre code fonctionne correctement en exécutant vos tests.

Si tout fonctionne, ou après avoir fait les changements nécessaires, et que tous vos tests passent, vous pouvez

Vamos começar com um exemplo de **caso de uso** e então ver como resolvê-lo com isso.

Vamos imaginar que você tem alguns **modelos de machine learning** que deseja usar para lidar com as requisições. 🤖
