Project Flow - Testing & User Validation

Hi Dribbble. So, here's the last piece of this collection. Say hello to 'Testing & User Validation', that stage that has such importance obviously, because we work hard for the client but most of all for the final user. So, validation with testers is the last step we have before launching any project where the input we extract is so close to what real user would give but, better before than after right?
