Today, the cost of error in the final version of the mobile application is extremely high: the negative assessments and feedbacks from the first users can alienate the new ones, thus preventing the project from taking the leading positions. The updating (defects elimination) for the mobile applications is realized with a delay because of the process of harmonization of the new version by the administration of the app store. Besides, the restoration of application’s reputation is a long and labor-intensive process, which will take a lot of time and energy. Therefore, mobile app testing service is a very important process for the developer companies and business owners that expect to get a mobile audience.

Today, the number of mobile developments is just incalculable. Therefore, if one application doesn’t meet the user expectations, he/she just applies to the other one, leaving the negative comments in the app store, which will definitely affect the number of downloads and the further development of their product. To prevent this from happening, the qualified experts (within the of web-application testing) realize:

Testing of updates
The compliance of application with the operating system requirements isn’t permanent, as the latter are constantly updated, which must happen to your application as well. Quite simply, without requiring some specific knowledge from the user. The quality of updated application is one of the most important aspects that must be controlled to achieve the users’ loyalty and further development of the product on the market.

Testing of internationalization
Language support is the easiest, but at the same time serious way to significantly increase the target audience. Certainly, everybody likes it when the necessary application is translated into the native language, and all the buttons and pages are understandable. It is good if such goal has been set before the beginning of development, and the tests were carried out in the process.

Testing of usability
Its goal is to define which elements of application alienates the target audience. This testing also helps to identify which operations complicate the further use because of the non-intuitive interface and estimates the user’s learning ability by performing similar actions. It can identify the functionality that don’t achieve its targets or is insufficiently popular among the users.

Load testing
This kind of testing explores how the behavior of application– its system resources and memory – with different loads, which allows eliminating the weaknesses of performance and insure your application against unexpected critical errors and failures. The necessity of such testing increases as the rate of final users increases (even if the potential ones). If an application makes calls by means of Internet connection, the client-server part of product is certainly subjected to this kind of testing.

Random testing
So-called “monkey” testing is carried out to ensure an adequate behavior of application in the unusual conditions of use- for example, in the chaotic obtaining of useless information (unlocked device in your pocket).

Cross-platform and multi-device testing
The application must performed equally well on the devices with different hardware, functionality and screen resolution, irrespective of the version of operational system. This study allows you to ensure that the operation of this application is not violated in different configurations. The experts offer the optimal set of devices and versions of operational system based on the global and regional statistical data. These measures will allow you to prevent the negative experience of work in the application for more than 90% of users.
