Inspiré des unit test que fait eclipse en java.
Cette source vous permettra de générer des fichiers unittest.h et unittest.cpp à joindre à tous vos projets pour tester vos classes. Elle permet aussi de générer des fichiers de unit test préformatés pour chacune de vos classes. Il ne reste alors qu'à écrire les tests à l'aide des fonction assertTrue(bool), assertFalse(bool) ou assertEquals(const T&,const T&).
Il suffit alors de runner le test qui s'occupe de l'affichage.
Un exemple complet est fournit dans le zip.
Pour des questions ou des notifications de bug n'hésitez pas à me mailer !
Bon amusement ! :-)

Conclusion :
à venir:
- parseur pour éviter à l'utilisateur de taper les fonctions à la main (et ainsi des risquer des erreur dans le fichier généré)
- possibilité d'ajouter des unittest à un fichier
- interface plus sympa que la console ( peut-être un jour... un motivé pour le faire ? :-D )
