Introduction to Mobile Application Testing Basics

Smartphones and mobile application are rapidly growing and have become an essential part of our day to day life. The new generation like to prefer mobile applications for various small or big tasks. Mobile applications testing basics have changed the whole aspect of our life. With the modernization of mobile applications testing basics, every person has very high expectations from these apps and even a small error or mistake is not acceptable. Thousands of new apps are created every day. Various challenges are faced by the technical team while testing the accuracy of the mobile applications.

Mobile Application Testing Basics & Challenges

Following are the mobile application testing basics & challenges:

Network connectivity

There are several standards for mobile data applications like 2G, 3G, 4G, 5G or Wi-Fi. Different mobile applications require a specific bandwidth to perform the task adequately. The consumer moves around from one place to another so network connectivity is changed with the movements and application performance is also changed with the network variations. Sometimes, while using any mobile application features, maybe there is no connection on the device so it is necessary to test the performance of the application while less connectivity with network connections.

Operating system version

There are different types of operating system available in the market. Every operating system has its own way of working and different kind of limitations. Testing of each application on various devices with different operating systems is a very complicated challenge in front of testers. Device fragmentation is the most complex part of the mobile app testing. Os versions are quickly upgraded to the latest versions. The mobile application testing basics must have been developed with keeping up gradation of OS in their mind. So that the mobile app will be able to provide a fluent experience to the user with various OS platforms.

Different types of mobile application testing basics

There are mainly three types of mobile apps such as web app, native app or hybrid apps. Functionality and implementation technique of every app is different from each other. It is very complicated to test the app performance from installation to the functionality of every different type of app.

Application usage

In mobile application testing basics, it is very important to pay attention to all the key areas of the app functions. Usually, the mobile screen is small and the applications require displaying a lot of information at the same time. It is very typical to display every function on the screen with a clear resolution. Font sizes and click areas require extra attention for the smooth working of the application. It is necessary that the click areas have the proper size and all the text is easily readable. Testing the app with all these challenging factors of usability is not an easy task.

Function testing

Applications need to test the proper working mechanism for the various type of functions and user requirements. User interface drives various type of test to check the proper functioning of the applications on various devices.

Diversity in devices mechanism

Mobile devices are different from each other on the basis of screen sizes, hardware system, and input methods. A wide range of handsets, tabs, smartphones, and iPads are available in the market. Mobile apps have to face the huge diversity of the technical environment. All the handsets and devices have their own working mechanism. Testers have to check the performance and adaptability of the mobile application features with all the compatible devices. It is not necessary that if an application successfully working on a handset, is also performing well on the other device. Quality tester is never able to give 100% assurance for the compatibility of the mobile app with all the devices.

Uses of various testing tools

A huge variety of mobile test tools are available in the market. Different tools are used to test the different type of applications like for native and hybrid applications testers have to use different tools. Mainly two types of automated tools are used for the application testing are image-based and object-based. In the image basis method test of applications are based on screen co-ordination. In this method, a written test script is necessary for each variation in the device screen size. In the object base tools, the elements of the screen are mapped onto objects for manipulation. So selecting and implementing the perfect automation tool according to mobile automaton needs is a complicated task.

The discrepancy in device screen dimensions

Every device has different display dimensions and pixel densities. Mobile application testing basics required adapting the design of the device screen. Different aspect ratios and a variety of pixel density is an unavoidable difficulty. It is necessary that the app has the equal accessibility of all the screen elements. For this purpose, the app requires to test on various different devices having dissimilar screen displays.

Universal usage

With the increasing demand and popularity of mobile apps, it is required to test the apps for the use on a universal level. Today most of the popular mobile apps are designed according to the use in international markets. Every region have its own language and a writing pattern like in some languages right to the left pattern is followed and in others left to right. So it is very difficult to develop the app according to all languages and writing patterns. Tester has to pay extra attention to the functions like area setting, time zone, language setting, and other key factors to make the app compatible for usage on the international level.

Variation in battery capacity of the device

every mobile app requires different battery strength for proper working. Some apps consume full strength of battery and other requires low strength. Power consumption is an important aspect regarding the mobile application testing basics. No one wants to use such type of applications which consume high power battery consumption. Whether these apps are efficient or not it can never become popular among the users. Battery consumption always becomes a barrier in front of the usability of the app. Applications need to be tested for different kind of interruptions and this is a major complexity in testing the various apps.
