Etat de validation de DataLab

Validation fonctionnelle

Dans DataLab, la validation fonctionnelle est basée sur une stratégie de test classique (voir Validation fonctionnelle).

La couverture de test est d’environ 90%, avec plus de 200 tests.

Validation technique

Ce paragraphe fournit l’état de validation des fonctions de calcul dans DataLab (c’est ce que nous appelons validation technique, voir Validation technique).

Note

Il s’agit d’un travail en cours : les tableaux ci-dessous sont mis à jour en continu à mesure que de nouvelles fonctions sont validées ou que le code de test est adapté (les tableaux sont générés à partir du code de test). Certaines fonctions sont déjà validées mais n’apparaissent pas encore dans la liste ci-dessous, tandis que d’autres sont encore en cours de validation.

Avertissement

L’état de validation ne doit pas être confondu avec la couverture de test. L’état de validation indique si la fonction a été validée par rapport à des données de référence ou des modèles analytiques. La couverture de test indique le pourcentage du code qui est exécuté par la suite de tests, mais elle ne prend pas nécessairement en compte la justesse des résultats (la couverture de test de DataLab est d’environ 90%).
