Although we have more and more memory in our phones, taking care of good memory management is still necessary. The OS will kill apps that use too much memory, so a developer must care about memory leaks and optimize long-running operations.

Automatic testing is used on applications in critical scenarios where regression tests have to be repeated. Yes, there are certain factors that the users have to pay attention to. The very first thing is to make sure that the installation of every tool has been taken place properly. The next thing to pay attention to is to assure the launch of the application when no network is available. The very first one is storing the test cases together with the source code.

Mobile device testing examines a device’s quality – by validating its hardware and software functions.This process aims to test features, i.e., screen, memory, camera, applications. It also consists of factory testing and certification testing. Still, we need you are love and support to make this platform more helpful to our fellow testers. So it would be great if you will share your recent interview questions and experience with us.
