. Une-erreur-de-précondition, Nous nous retrouvons dans une configuration similaire au cas précédent. Néanmoins, il n'est pas forcément nécessaire d'exécuter l'opération pourévaluer pourévaluer sa précondition, Comme nous le verrons plus loin, ce dernier point permettra certaines optimisations plus efficaces

. Si-nous-prenons-comme-référence-junit, aucune optimisation n'a ´ eté prévue. C'est-` a-dire que l'outil n'essaie pas de retirer des informations des tests précédemment joués. Ceci se justifie bienévidemment bienévidemment par le fait qu'il n'a, a priori, aucune information sur la structure des tests qu'il doit jouer puisque ceux-ci sont des méthodes pouvant utiliser toute la puissance du langage Java, Tobias, les tests sont nécessairement des séquences. De plus, nous avons vu que les tests générés par Tobias comportaient de nombreuses similitudes, exploitables pour optimiser l'exécution des tests
