Businesses continue to integrate and deliver mobile applications with innovative and smart functionality to engage millennial customers. The quality assurance of mobile applications for their efficiency, performance, and robustness will leave customers with an exemplary experience.

The mobile application is very different from the desktop one. So, we should take this into account when planning the testing process.

Installation Testing: Application Installation Testing is generally carried out before your application first interacts with its customers. The application should be able to search and install properly on a number of devices. It should be installed on all platforms including iOS, android, windows, etc. The application's icon should be clearly visible in the menu tray and on a home screen. The version number of applications should be the same as it was on a time of submission. Apart from that, files and other integrated data should properly be installed on-device storage. Also, this section covers the upgrade and uninstallation of Mobile applications.

Functional Testing: Each application is built with a purpose. Functions and features of an application are unique and as per the customer's requirements. Functional testing is a testing technique where tester needs to test the feature/functionality of the Mobile application. During this testing, the technique application should not be crashed. Mobile Application Functional Testing is done to validate that each and every component of the application is working as expected. If there is a text field of the phone number, the keyboard type must be a phone pad type.

Performance Testing: As its name suggests the performance of application should be tested on various platforms. It also includes testing a device performance, server/API performance, and network performance. All images and audio files should be loaded on time without having a delay. Variation in hardware and software is also essential in performance testing. For instance, an application is working well in the android noghut version but it is not working properly in kitkat version of android. So these things should be kept in kind of a tester.

Memory Testing: There is limited storage in mobile devices. Regardless of external storage in the android device, the iPhone has no external storage function. So memory testing id very important in-app testing. After performing a certain task automatically the memory consumption of the app increases.

The good thing is availability of testing tools. iOS provides leaks instrument of the Instruments analysis tool to find objects in your app that are no longer referenced and reachable. For Android use Eclipse Memory Analyzer Tool or Android Debug Monitor.

Interruption Testing: Interrupt Testing is a branch of Mobile Application Testing that deals with- how an application reacts to interruption and resumes to its previous state. There are many Interruption occurs while using an application that is mentioned below.

• Incoming Alert from another mobile application

• Incoming phone call/SMS

• Battery low/Battery charged

• Application Update reminders

• Alarm

• Network connection loss

The mobile application needs to manage these types of interruptions to satisfy user requirements. Normally all these interruption testing are suggested to test with a real device.
