Well, this is it. Your project is ready to start. Everything seems to be done right, but you can't be sure until it went off the air. And even then something happens Forrest Gump-style. And even minor crash can break user's impression, break the 5-star rating on the store and turn your day upside down. We know how that feel. And to avoid it, we always using our QA squad to be sure everything is done right and running. And will do that forever. And it goes. So before the start tell us to test your project. There is always something to improve.
