Smartphones have become an integral part of every individual’s day to day life. This has led to an exponential increase in the number of mobile applications available in the market, catering to various needs of a person. Be it booking a flight, transferring money or getting food delivered home, a person can do almost anything by using these applications. Thus, a need to make these applications more user-friendly and bug-free becomes an important part while developing and testing them.
The scope of mobile application testing becomes vast since there are a large number of smartphones, operating systems, screen sizes, etc., available and the applications need to provide a smooth user experience for every device type.
In this blog, I want to list down certain aspects that need to be considered while testing mobile applications.
1- Functional Testing: The first and foremost part of testing any application is to check the flow and see if the application works around all the scenarios for which it was developed. The application should install properly, and all the UI components should function according to the requirements.
2- Usability Testing: Usability testing involves the overall user experience with the application. To increase the user base, we should always provide a smooth experience and keep the complexities in accessing any part of the application to a bare minimum. The layout of the application should be user-friendly, and the application should be intuitive so that even a non-technical person can use it with ease.
3- Compatibility Testing: With the variety of devices available, the need for compatibility testing becomes even more important. Compatibility of the application should be tested with respect to:
(1) The various OS (Android, iOS, Windows, OxygenOS-customized version of Android, etc.)
(2) Cellular Networks (3G, 4G, 5G) or Wi-Fi
(3) Dark theme – Nowadays, the dark theme has come into the picture on various devices, therefore, applications that support the dark theme should function properly in that mode.
4- Interrupt Testing: The application should work even if there any external interrupts occurring during its usage. External factors that can affect the normal flow of the application include phone calls, SMS notification, low battery warning, network interruption, etc. The application should resume its normal flow even after such break-ins.
5- Security Testing: A lot of private data of a user is saved on the smartphone. The application should not interfere with the internal files, until and unless it is one of the requirements, wherein, the user must grant permission to use that data (such as contacts or media files) and permission requests must be properly handled. Confidentiality and integrity should never be compromised. In the case of jailbroken or rooted devices, the application should not provide support.
6- Don’t Keep Activity (Android): The Don’t Keep Activity feature is only applicable to Android. If this feature is enabled, then it might lead to unusual behavior of applications. Basically, this feature tends to recreate an activity of an application that has gone into the background and so the activity loses its data. This occurs due to a memory crunch. The testing of an Android application in this special scenario also comes into consideration.
7- Update Testing: With frequent updates that are provided for an application, the process of testing the application in case the user does not update his/her application should also be tested. The application should work without any problem for a new as well as an existing user.
Certain mobile application testing tools are also available in the market that can be used like Katalon, Appium, Selendroid. In all, testing of mobile applications needs to cover a lot of scenarios and keep in check the number of changes that happen in the underlying technologies for which the applications are developed.
