The world is a connected mobile data hungry place. It used to be the work of websites and desktop PC’s but over the last 10 years we have rapidly transformed into a miniaturised IAAS (Internet As A Service) platform of ever connected mobile nodes. APIs and databases have been taken over by apps and mobile messenger connectivity, 4G, Fibre. Think Facebook, Instagram, Snapchat all created by now who are billionaires interfacing directly through your mobile device – which is in all actuality, has become the common standard for communication.
Competitiveness through stability
This is the main reason for a mobile app presents and compatibility, access to 
the masses of the teen marketplace and a chance to gain a reputation of an arena, where all the successful devs, now are barrons of the developed mobile cloud and app store industry. Evan Spiegel, CEO net worth 3 Billion, says the mobile platform was fundamental to information in the post 2000s generation. Reliability, Java development making the 2 million lines of code, leading to the creation of Android and the development problem Android Studio , has kick started this software development renaissance.
Memory, Data and battery requirements testing
Fundamentally devices can be assessed for usability to look for potential 
abnormalities, with battery usage, bandwidth needs and memory consumption. This is all basic reinforcement of stable development and functionality testing. And allowing for bug identification and finalising of initial UML system design and verifying kernel (core services) installation, general software integrity. This includes different hardware specifications and operating system layers
Security testing
Without secure data your user lose trust in your app. Https and other secure 
protocols can be verified and further assessment of where 2 step verification like token 2fa confirmation is needed. Apple and Android use DTSL (security protocol) uniquely as regulated by FIPS (Fed IS Security) and BCS (Computer Society). Testing allows for compatible and successful security method implementation. This guarantees module integrity relied upon by protocols like SHA 256 encryption and OS services and UDP firewall security.
Opportational methods
Testing of backups and recovery plan, if the battery fails or connectivity issues during initial app store download. This requirement ensures software functionality in the event of extreme hardware failure and builds trust when service is restored and the health of the integrity of the application is maintained for the user.
