Challenges in mobile application testing
Mobile application testing is a process by which application software developed for mobile devices is tested for its functionality, usability, and consistency to make sure that the application is working as expected.
As we all know in this fast growing technology world mobile has become one of the most important devices in our day to day life.There are varieties of application available in the market.
1. Compatibility of an application on different platforms/versions/screen sizes
2. Testing in different networks
3. Usability testing
4. Out of memory issues
5. Localization Testing
6. Battery consumption testing
7. Regression testing on mobile application
8. Application update
1.Compatibility of an application on different platforms/versions/screen sizes:
As we all know there are various platforms like
Each of these platforms has various versions. Compatibility of the mobile application with different versions has become one of the major concern in application testing. It is our responsibility to check whether the app is working across all the versions of a platform. We can’t assure the compatibility of the app by checking only in one version. So it has become necessary to test an app on different platforms and different versions as well as different size of device screens. It is a time-consuming process.
2.Testing in different networks conditions:
Network performance can also have a powerful impact on user experience with a mobile app. We should ensure that the application is working as expected in different networks and different environments.
The response time of different devices varies based on their memory parameters with different network types. The application should work properly under any network conditions or any other reason.
Usability testing is one of the most important types of testing performed in the mobile application testing.To make sure that mobile application is very easy to use and provide the good experience to the end user since the device display area has limitations and all content should be fit in smaller screen device as well as bigger screen devices.Throughout, the application should maintain toast messages for alerts else proper pop-up notification in failure cases. Navigation style is different on different platforms, example: iOS, Android
4.Out of memory issues:
During the testing of the mobile application, most of the times we use to get out of memory crash issues those crash are randomly and don’t have proper steps to reproduce the same crash issue on the same screen.This issues would occur on some devices and not present some high-end devices.We should make sure our application should not crash anywhere due to out of memory. Also, the application should not get a crash if a customer runs other applications in the foreground.Also due to crash, there should not be data loss.
-Localization might bring changes to text and that means possible overlap, Text/Button alignment issues, etc.
-Few of the features might not function in different languages
-It will bring layout issues also.
-We should Pay extra attention for dates and calendars, they will probably end up in need for some fixes.
6.The significance of battery consumption testing:
One of the major problems of a smartphone user would be battery backup of a mobile. It’s important to keep a track of battery consumption while running application on the mobile devices. We should make sure that the app is using the minimal amount of energy and it should not be a battery drainer.
7.Regression testing on the mobile application.
It’s fun to design, develop, and deploy new features but it’s important to make sure your new changes will not break existing functionality, introduce new bugs, or reintroduce previously resolved bugs. This kind of work can be less exciting that working on the new stuff. After establishing a testing strategy, the regression testing can be optimized to get the most value out of the efforts. There is rarely a need to test every possible combination of platforms, operating systems, and devices – so the strategy is to identify the high-risk areas and focus on those.The best approach to regression testing is often a mix of manual and automated testing.
Make sure application should not break on updating from lower version to higher version on different versions of OS and we are responsible for making sure that there is no data loss because of application updated from the previous version to new version on different platforms and versions.
I am sure you would have got crash issues due to memory allocation as well as a different network of low speed. We would love to hear from you the challenges that you faced while reproducing these crash issues.
