Carsales has been through a huge leap on efficiency in the past few years. We moved to micro service architecture, we went from doing deployments 1-2 times a week to multiple times a day. We migrated from gigantic legacy system and put our system in the cloud at the same time improved quality. How did QA team in Carsales manage to ensure the quality of every release? Also, how did we not slow things down but helped to make delivery smoother and provide the team with more confidence? I will talk about the improvements we did beyond automation, to help us keep up with the pace.
