Ma il ruolo del tester in un team agile a cosa serve? E' una domanda piuttosto ricorrente nella comunità agile, a cui spesso ci si risponde con uno sdegnato "in un team agile non servono persone di QA!".

Approfondendo l'argomento tuttavia, si scopre quanto il testing abbia un ruolo di fondamentale importanza anche in un ambiente agile.

In questo intervento verrà trattato come inquadrare il QA nell'ambito di un processo di sviluppo agile, con riferimento alla realtà del team di sviluppo di Funambol.
