Hope you have heard the famous advertising title – “There’s an app for that”. Quite literally, there are Mobile Apps available for everything. But before being available to end-users, Mobile Testing is an important phase of a mobile app’s development stage. As the war between Google and Apple rages on, there is a battle in the testing world that mirrors the epic giants. Android & iOS Mobile App Testing is often quite different. A Tester must be able to test on both OSes and in order to do that it must, first of all, know only the differences which have an impact to his/her testing process. The purpose of this post is exactly that: to focus on differences between iOS and Android that a tester must know.
