Framework de tests

Le framework de test utilisé est Jasmine. C'est est un framework de tests open source pour JavaScript. Il possède une syntaxe assez facile à prendre en main. Les tests unitaires sont des méthodes permettant de tester de façon unitaire des éléments d’un code source. Leur principal objectif est de vérifier le bon fonctionnement de sous-ensembles de code tels que les fonctions, les procédures, les classes, etc. Les tests unitaires garantissent que ces éléments de base fonctionnent comme souhaité et préviennent des potentiels bugs.

Localisation des tests

Tous les tests sont situés dans le fichier test/ControllerSpec.js. De nouveaux tests peuvent être ajoutés dans ce fichier.

Fonctionnement des tests

Les tests sont facilement lancés par l'ouverture du fichier test/SpecRunner.html dans un navigateur.
