It is hard to imagine modern life without mobile devices and therefore without mobile applications. An integral part of the test mobile application development. A responsible approach to the organization of mobile application tests will measure the time to test properly and create high-quality products.

| Features Of The Planning Of Work On Testing Mobile Apps |
The cost of testing errors is very high. Therefore, we will examine the main aspects that you need to be careful when testing mobile applications.
Preparation for planning
Before starting to prepare a test plan, you must determine the limits of this test. You should have a list of platforms, operating and devices you want to test mobile application systems.
The choice of platform is generally determined by the purpose of the application and customer requirements. Applications for a wide range of users are usually released on two platforms: iOS and Android (according to statistics, 98% of applications are created on iOS and Android platforms, and only 2% use other platforms forms). Very specialized applications or games are typically implemented on the same platform.
OS Version Selection
It is best to get the most popular versions of the official sites and developer.android.com developer.apple.com. Do not forget the old versions, since all smartphones and tablets allow you to switch to a popular or latest version of the operating system, and many users do not want to.
While working on a long-term project, it is necessary to redesign versions for testing. In the new versions, some components of earlier versions cannot be supported, which will require refinement of the mobile application.
Selection of device models
Due to a large number of manufacturers and models of smartphones and tablets, it becomes clear that it will not work to cover the whole range of devices during testing. Therefore, you should choose several models that differ from each other specifications (screen size and resolution, memory size).
You use emulators instead of buying the complete range of mobile devices. You will have to potter with their installation, but in return, you get access to all the necessary templates and the ability to rapidly move a device to another. Emulators are essential to test the layout and geolocation. In this case, you must understand that the emulator will never replace a real device. Also, do not waste time on simulators, as they simply represent the original device's environment and do not affect its filling (hardware), and it can affect the result.
Thus, for the full test of a mobile application, you can limit yourself to 3-4 actual devices, and if necessary, carry out random tests (testing the main functions of the application) on emulators.
Test planning
After setting the test limits, you can begin to plan the work itself. Note that a mobile application testing takes much more time to test a website or a desktop application because it is necessary to take certain functions into account and set the time for the following additional controls:
• A requirement of completeness and internal consistency test;
• API version compatibility tests;
• Test the application on different physical devices;
• Usability testing.
Testing requirements
The requirement to phase in the app's development is essential. However, no matter the amount of time needed to develop this phase, the appropriate requirement tests should be performed when testing the application. Needs analysis must be done before the application developers begin the development process, as this will reduce the number of errors. After the development of the application, the overall functionality of the application needs to test, and fitness tests should also be done.
API Compatibility Test
Another factor increasing the test time is the constantly evolving functionality of the web application, by analogy with what has been implemented in a mobile application. The program releases have not kept pace with changes in the web version, the data structure has changed, and Web services have continued to return the required data to the application. In this regard, the test API has become an integral part of the process.
Test on physical devices
At the stage of functional testing of key controls compliance of application functions with specifications, it is necessary to conduct application testing in various situations, namely:
• Transition to fashion background when receiving calls and SMS;
• Operation of the application when connecting to other devices;
• Work with different types of Internet connections (Wi-Fi, 4G, 3G);
• managing the lack of communication situations (message display when the Internet connection is disconnected and properly take during the restoration);
• The resettlement process and to update the application to a new version.
Since these controls are very dependent on various technical conditions and specific situations, during their production, you cannot do without actual devices. Also, the emulators of mobile phones do not give you true indicators of the speed of the application, the performance, and responsiveness of a real phone. Also, it is difficult to assess the convenience of the application on the emulator. Most functional tests can be performed using emulators, but you can check the application behaviour in real conditions using smartphones and tablets real.
Usability testing
Another inalienable step of testing a mobile application is usability testing. It is essential to provide the user with maximum comfort during use of the application, which implies the following conditions:
• working speed;
• Simplicity and understandability of the interface;
• Minimum data entry from the keyboard;
• The presence of an indication (answer) to user actions.
In conclusion
We can say that when testing a mobile application, we must pay particular attention to the choice of the fleet of devices under test, take the time to test and API needs into account. And also you must perform a full qualitative verification of the application's behavior in real conditions of use of a mobile device. The most important thing is to provide the user with the simplicity and convenience of working with this mobile application.
