Mobile testing is a service that provides a testing strategy to the application developers who are targeting the mobile users. These include native or hybrid apps or websites that are likely to be viewed on mobile devices. These apps include native or hybrid apps or websites that are likely to be viewed on mobile devices.
Mobile testing is incredibly important for eliminating bugs and other defects. It is a basic form of testing that includes everything and anything pertaining to catching bugs to detecting other faults. This also caters to systems that will be running on a mobile device with limited resources in comparison to laptops and desktops that have wider scope and memory. Apart from this, some of the other things that mobile testing caters to:
- Smaller screen resolutions
- Wide device defragmentation to be supported (especially with Android).
- Different ways to interact with apps, behind keyboards and mouse clicks.
It should be remembered that mobile apps and desktop apps should be treated differently. This is because if you test apps meant for mobile on desktop, you will be missing out on some of the real test scenarios.
Some of the factors that one should keep in mind, while testing for mobile applications include:
- The app must download successfully on the mobile
- It must be functional
- It should be able to interact with the backend content infrastructure
- When updates are made, the app should be able to accept it, with the help of the end user.
- The impact of low signal strength, 3G and 4G networks on the applications.
- Impact of low battery and other phone functionalities.
The next big step is to decide when to use real devices and when to use emulators. Emulators are good for user interface testing and initial quality assurance, but real devices are essential for performance testing.
Device cloud testing, on the other hand, is an appropriate way to scale up the number of devices and operating systems.
Emulators versus Real Devices
Emulators are mostly preferred because they are cheaper than mobile devices. They are also faster in catching bugs during the process of testing. With emulators, one can delve into code, file structures, and databases in real time.
However, technical experts think otherwise. It is believed that running tests on emulators is more of a bane than a boon since mobile users use real devices rather than emulators and therefore the challenges will be different.
Testers would not know the difference between how much of the CPU and the memory the application would use on the mobile if the testing is done on an emulator. Some testers are of the firm belief that emulators cannot test mobile applications at all since there are mobiles of varied configuration and settings.
Having said that, it is also important to understand that there are cases when the tester should avail the positives of both the real devices and emulators. For instance, changes that affect both the user interface and mobile app architecture are best tested with a combination of real devices and emulators. The stage of testing is also important for determining whether the tester should use real devices or emulators. For instance, an emulator can be used to verify the look and feel of the app. Then the tester can go ahead in testing the application on real devices.
