Usability testing is aimed at ensuring ease of use of the application, creates an intuitive interface that meets accepted standards. It is designed to create fast and easy to use applications. For the Mobile Application Testing Services this is essential. Here are the main criteria for evaluating applications:
- Satisfaction
- Efficiency
Let’s look at a simple checklist to test the usability of mobile apps:
- Make sure the buttons are normal in size and located on the same screen area.
- Make sure the application is multitasking when necessary.
- Check the navigation of important application modules.
- Make sure that the icons and pictures look natural in the application environment.
- Make sure the color of the buttons that perform the same function is the same.
Ensure that application components are in sync with user actions. Make sure that the user can return or cancel the action if he pressed the wrong button. Make sure that the response speed of the element is high enough. Some useful tools for checking the usability of mobile applications: User Scale, Reflector, Loop 11. The text should be simple, clear and visible to the user. Short sentences and paragraphs can be read.
Determine the optimal font size.
Ensure that the Zoom-in and Zoom-out systems are working properly. Make sure that context menus are not overloaded. Make sure that the application can be terminated from any state and that it resumes operation in the same state.
User Interface Testing
User Interface (UI) testing is performed to ensure that the graphical user interface of your application meets the specifications. Here are some checks to test the mobile app interface:
Ensure compliance with UI standards
Check the user interface of your application with standard screen resolutions: 640 × 480, 800 × 600, 1024 × 768, 1280 × 800, 1366 × 768, 1400 × 900, and 1680 × 1050.
Check the responsiveness of applications on different devices. Test the main design element: buttons, icons, colors, links, fonts, font sizes, layout, text boxes, text formatting, labels, labels, buttons, lists, etc. Make sure that the ads do not overlap the application control buttons. Make sure the ad has an available close button. Make sure that the various elements on the retina are displayed correctly and without the retina. Make sure all items are displayed in portrait and landscape orientation.
Some useful tools for testing the interface of a mobile application: FitNesse, iMacros, Coded interface, Jubula, LoadUI.
Compatibility testing configuration
Testing for compatibility configuration is carried out in order to ensure optimal application performance on different devices taking into account their size, screen resolution, version, hardware, etc. You should pay attention to the following points:
- OS configuration
- Browser configuration
- Database configuration
- Device configuration
- Network configuration
Cross-platform testing will help you test a mobile application in different OSs: Windows, iOS, Android, BlackBerry, etc. Cross-browser testing allows you to provide correct application operation in various browser configurations: Mozilla Firefox, Google Chrome, Opera Mini, etc. Database testing is designed to verify the correct operation of your application in various database configurations: Oracle, DB2, MySql, MSSQL Server, and Sybase.
Testing the device configuration
The following parameters should be considered:
Device Type: Smartphone, Tablet, etc.
Device configuration: RAM processor type, screen resolution, battery capacity, etc.
Network configuration testing is performed to ensure proper operation in various network configurations (GSM, TDMA) and standards (2G, 3G, 4G).
