J'ai roulé le mien parce que je n'avais pas le temps d'apprendre à quelqu'un d'autre façon de faire les choses, cela a pris environ 20 minutes à rédiger, 10 à l'adapter pour le poster ici.
Unittesting m'est très utile.
c'est un peu long mais ça s'explique et il y a un exemple en bas.

Cela produit:
Test: TestOne était un échec
/ **
* Ce test est conçu pour échouer
** / (lignes: 149-152; fichier: /Users/kris/Desktop/Testable.php)
Test: TestTwo a été un succès
