Mobile Application Testing:

Testing the applications which are developed and designed for the mobile devices is known as Mobile Application Testing. Test the application for its functionality, consistency, and usability. But, there are few basic differences in the mobile applications:

a) Native apps: These apps are built for use on a particular platform or device.

b) Mobile web apps: These apps are server-side apps. We can access the websites on mobile with the help of different browsers like chrome, Firefox connecting with a mobile network or WIFI.

c) Hybrid apps: These apps are the combination of native app and web app. They are written using web technologies like HTML5 and CSS.

Testing the mobile apps is more difficult than testing the web apps on desktop because of the following reasons:

• Different range, screen sizes and hardware configurations of mobile devices.
• Many varieties of mobile devices (HTC, Samsung, Apple and Nokia)
• Different mobile operating systems (Android, Symbian, Windows, Blackberry and IOS)
• Multiple versions of OS (iOS 5.x, iOS 6.x, etc)
• Different mobile network operators (GSM and CDMA)
• Frequent updates – (like android- 4.2, 4.3, 4.4). Testing on each update to ensure that functionality of an application is not impacted.

Types of Mobile App Testing:

Below are the testing types which are performed on Mobile applications:

Usability testing:

Ensure that the mobile app is easy to use and provides a satisfactory user experience to the customers.

Compatibility testing:
Ensure that the mobile app is working perfectly on the required mobiles devices, browsers and OS versions.

Interface testing:
 Test menu options, buttons, bookmarks, history, settings, and navigation flow of the application.

Services testing:
Test the services online and offline.

Low level resource testing:
Testing of memory usage, auto deletion of temporary files, local database growing issues.

Performance testing:
Test the performance by changing the connection from 2G, 3G to WIFI.

Security Testing:
Verify that the information system protects data or not.
