If I can’t use it anywhere I would use a regular coroutine, what’s the point of mocking it ?

Did I use it wrong ?

Elle surcharge le paquet standard unittest pour ajouter des fonctionnalités permettant de tester du code asyncio. Elle inclue des outils pour facilement faire des mocks de coroutines (y compris avec de l’auto-mocking ou patch()). Elle permet aussi d’utiliser directement des coroutines dans les fonctions de setup, teardown, test ou cleanup (ce qui fait économiser pas mal de boilerplate).
