In present times, people use multiple devices to perform their day to day activities, be it booking a flight ticket, or watching a show on Netflix or buying stuff online, the corresponding portals are accessed from desktop, mobile devices as well as tablets. Before launching any application, a developer or an organization should carry out testing for multiple devices to ensure that it can be accessed from anywhere without causing any breakage. Let’s discuss why multi-screen behavior is required and how it affects testing.

There are several factors to be considered that can lead to failure of critical functionalities of an application when executed on multiple screens. Let’s look at stuffs a tester must observe while performing multi-screen testing.

The primary factor to test is responsiveness of an application. The application should fit properly on different screens without misalignment of objects or horizontal scrolling.

  • Often it has been observed that buttons, dropdowns or checkboxes does not work in certain devices. This may happen because of small button size or hidden focus fields because of responsiveness.
  • The tester should check the font sizes in different screens to ensure that the content of the application is properly readable in all devices.
  • In case of mobile or touchscreen devices, one thing should be checked, whether the buttons or dropdowns are clickable or not. In desktop, this is not an issue since the mouse pointer can easily pinpoint and click of a button. But in touch screen devices, users must use their fingers, which means, a button is clicked with not a pointer but a half centimeter thick cursor. It must be ensured that all the buttons, dropdowns and checkboxes are clickable with the use of index and thumb fingers.
  • If advanced features like gesture control, augmented reality or fingerprint scanner are embedded in the application, testing should be executed in all devices to check whether those features work properly since breakage of any of those functionalities may affect usability of the application.
  • Last but not the least, a major problem faced by testers is device selection. Leaving desktops and tablets apart, for mobile devices, 2 major operating systems are Android and iOS. In case of iOS, Apple has a restricted device distribution. But no such thing is there in Android. There are hundreds of companies releasing Android devices every year, each with different screen sizes, customized operating systems and different browsers.
