Website on Mobile Device Testing is needed to make sure the website opens correctly on mobile devices, i.e. its pages are loading at a high speed, and its interface is easy to use and navigate. Testing activities include mobile website test performed on real devices as well as mobile responsive test.
Why is it necessary to test mobile website versions on real devices?
Proper testing of mobile versions of the website allows you to identify the factors affecting its loading speed and time. Optimizing such factors as image size and encoding, js-script and css settings, hosting settings and content compression makes it possible to increase loading speed of the pages by several times.
It is important to keep in mind that there is a huge difference between testing in browsers on real mobile devices and in their emulation. Emulators let you perform testing much faster, but the compatibility issues with specific devices cannot always be detected. Emulators only assume (quite accurately, though) how a particular browser works on a particular device but omit all the errors related to the specific behavior and interactions of a real browser on a real device. Therefore, if you require a guarantee that all possible bugs will be found, you need manual testing on real devices.
Mobile Website Testing Techniques
The most common types of manual and automated testing of the websites on mobile devices are:
- testing connection between the desktop and mobile website versions, which includes verifying how the users of specific devices are being redirected to the version of the website they need, checking how easy it is for the mobile web page users to access desktop version of the same page, searching for bugs in Vary-HTTP header settings and rel = alternate / canonical tags.
- identification of technical issues, i.e. checking the isolation of mobile pages from desktop ones, measuring the website loading time, testing program code support;
- User Experience (UX) testing on real devices, which involves viewing websites from smartphones and tablets operating on various platforms (iOS, Android), testing Viewport settings, media queries and page elements layout.
To test mobile versions of the websites, we use both testing methods, i.e. testing on real devices and on emulators which simulate a real device and allow us to perform testing on a single machine. At the same time, testing websites on real mobile devices is considered to be more effective, since it creates testing conditions that are as close as possible to actual use.
Our experts apply various techniques to test the functionality, compatibility, cross-browser and cross-platform operation of mobile websites, which allows us to detect and report all the bugs reducing the performance of the product.
