“Now, mobile apps are considered as the most attractive stuffs for the youth as well as old. It has made our life much active and easier than before. Apps include a variety of requirements like day-to-day useful apps, entertainment apps, games and basic apps etc. Top smart operating systems like Android, iOS and Windows are in the industry to provide platforms for the users to use these useful apps from respective app stores. The number of mobile apps is increasing significantly yet consistently in the past few years; the number has reached at around 1.5 million each for Android and iOS. The huge population of mobile apps is creating a competitive environment for the mobile app developers to build better and more useful apps to attract respective target audience. Quality apps can only be achieved with quality testing i.e. the success pillar for any application. Hence, there is a potential terror among the mobile app testers who strive for quality testing. For quality testing, here are a few checklists for mobile app testers.”
Functional testing: This is the basic yet most important testing process that must be performed by the tester without any failure. Moreover, the tester needs to test each and every module of the mobile app to find if there is any bug or error in the application. He must consider every aspect of the application and he must ensure that, all the modules are working perfectly fine in every type of situations. All the modules should behave in a normal and expected manner without any failure.
Interrupt testing: This is yet another testing process that has been highly used with the embedded system development projects and now it is widely used for mobile app testing. While designing a smart app, the developer must ensure that its app works fine in different unexpected situations. Situations like incoming call, SMS arrival, Low power condition, Sleep mode, and Airplane mode etc. can interrupt your app’s regular behaviour. To tackle these situations, the application must be smart enough to understand and feel these conditions. Then, the app should behave in a different approach so that, there is no hampering to the user’s data inside the app like User’s Score, Highest score, Last transaction, and other related information should not vanish. It is the task of the mobile app tester to ensure that, such types of interrupts are properly handled by the mobile app itself.
Performance testing: Who doesn’t care about performance? Especially when an app is running under many constraints like memory constraints (both RAM and ROM), Bandwidth issue, hardware limitations and operating system limitations (multitasking issue) etc. Hence, we must gift an app to the end user that can run absolutely smoothly under these constraints and this can only be achieved with high performance mobile apps. The app should be optimized from every angle like efficient cache management, improved use of local storage on the browser, light weight graphics, animations etc. Here the tester needs to check if there is anything that makes the application load and run slowly. He should also test if there is any unnecessary server communication that makes the app run slower than expected.
Platform specific testing: There are many platforms like Android, iOS and Windows etc. The app should be either platform specific or cross-platform compatible. And as per its category, the tester should test the app to ensure its working in those platforms. Suppose an app is designed for Android and iOS, then the tester must check if the app works fine on those platforms without imparting any bad experience to the end user. This is usually performed by testing if OS-specific libraries (JS and CSS files) are called in proper time or not.
Version specific testing: Apps are usually built for multiple versions i.e. the latest version along with few previous versions. But, is the app working fine in all these versions? That is the concern of the mobile app tester. The app tester must ensure proper behaviour of the app in all these versions for which the app is built. Considerations like app functionality, app size and app look and feel must be tested to ensure that, the app is working fine in all these versions of Android or iOS or Windows operating system.
Device specific testing: Operating System like iOS is device specific i.e. it runs only on iPhones and iPads. So, the app must work perfectly fine on those devices. Usually, iPhones and iPads have less RAM as compared to Android devices of that cost; still iOS runs extremely smooth on those devices due to highly optimized core inside. So, users demand similar user experience in their apps too. For that, the iOS apps must be optimized enough to work smoothly with those devices and it’s the assignment for the tester to ensure the same. A Similar case happens with other device testers as well for other platforms.
Network specific testing: We can’t ignore the importance of networks in any Smartphone; because, Smartphone needs mobile networks to perform different app tasks that deliberately use the internet APIs. So, in that situation the tester must check if the internet API is executed perfectly fine without any issue. Moreover, it’s the duty of the mobile app tester to ensure if the app behaves properly when there is no internet connectivity or very low signal i.e. the app should give alert messages like “There is No/Low internet connection!” or similar symbols to the user.
Resolution/Responsiveness testing: Mobile apps are consciously designed to run on multiple devices, screens and screen resolutions. It should behave in a normal way both in smartphones and in tablets; so the tester should test the app extensively in these devices with different resolutions. It’s nothing but the test of the responsiveness of the app which is extremely important in the current scenario.
User interface testing: This is the most important part of any mobile app development. The tester must ensure that, the app’s look and feel is as expected and should be engaging enough for the end user. It must have an attractive interface with interactive event driven objects on the app to make it popular among the users.
Reliability testing: Last but not the least; an app must work as expected in different situations including critical circumstances. The tester must check its behaviour with respect to changes in the environment. And in every case; it should work just like a normal app.
