Why is mobile application testing important?

In the last few years, testing of mobile application has become very important and a point of concern for the app developers.

If the mobile testing is done in a proper manner, the number of bugs can be significantly reduced and apart from that,

proper mobile application testing

lets you identify the bugs right at beta stage of the development lifecycle.

This saves your app the reputation on the market, and makes it possible to succeed and reach your business goal.

The term mobile testing is pretty broad and it’s important to break it down into specific types of testing for a better overall understanding of the subject:

Unit Testing

In this case, the developers themselves run the automated tests and each of these tests targets a narrow part of the overall application behavior.

Functional & Acceptance Testing

This type of testing is performed by the Quality Analyst team or certain automated UI testing frameworks do the trick as well.

Performance Testing

This type of testing is usually performed along with the profiling tools such as CPU profiling tools or heap. Apart from this, many mobile app developers are opting for mobile beta testing solutions in an attempt to gather data from real usage of the same. This also helps them to integrate app analytics for a better overall understanding of how the app works.

Certain challenges that may be faced during testing of mobile application

If you are willing to write native applications which work for each of the target platforms, then any testing on the code level will probably not be transportable. Apart from that, most of the scripted UI automation testing tools is not supposed to work for most of the platforms either. Even if these tools work, you will need separate scripts for each of these platforms.

Remember that there are hybrid solutions available for mobile beta testing, however, these in general, don’t work as good as the native tools when you consider the performance profiling.

Apart from mobile application testing, to make your app better, it is important to gauge the overall user behavior as well. This can be easily done by using a third party analytics services. Well, some of the mobile testing services provide their own analytics service as well and you can avail the same at slashed prices, therefore fitting your actual budget. Not only such analytics give you information about user engagement or demographics, you can use these third party analytics tools for measuring certain pieces of the actual app performance from within the real world usage. Real world performance metrics can actually turn out to be very useful when you decide to fine tune your mobile app depending on the needs of the users.
