École du tech lead: Conversation autour de la dette technique

----

TLDR de Cyrille Deruel @CyrilleDeruel

Les 3 phrases sur la dettes 
- Pas dépuration de la dette sans refactoring et pas de refactoring sans tests automatisés
- Normalement tu n'as pas besoin d'aller chercher la dette, c'est la dette qui te trouve 
- Ta dette tu la gères tous les jours
