An increasing number of users access websites on their smartphone or tablet. A variety of screen sizes and capabilities means that your website needs to be tested across the major mobile devices.
Users expect that websites they wish to access are optimised for the device they are using. Mobile screen resolutions accessing your website could be anything from 320 x 240 pixels up to 1920 x 1080 pixels.
Whether you have a dedicated mobile site, a mobile app or a responsive design, testing is important to ensure that the site displays and works as intended.
