"What to test"Mobile apps must provide the best user experience and are displayed correctly (UI testing) on a variety of smartphones and tablets in different sizes and resolutions (keyword "responsive design"). At the same time, apps must be functional and compatible (compatibility testing) with as many device specifications (memory, CPU, sensors, etc.)
