Commencez par reproduire le problème avec les deux tests pytest et comparez l’apparence de leurs docstrings dans le rapport Allure. L’issue ne nomme aucun fichier d’implémentation ni aucun test au-delà de cet exemple ; suivez donc la façon dont allure-pytest transmet les docstrings au rapport. Le travail est considéré comme terminé lorsque les docstrings sur une ligne et multilignes sont rendues de manière cohérente ; l’issue ne précise pas quel format de rendu est attendu.
