How many times have you encountered a situation where a particular web-page or complete website renders differently on different browsers? The situation becomes more complicated when the test is performed on browsers across different platforms & devices (Operating System – Linux, Windows, Android, iOS, etc. Device Types – Desktops, Mobiles, Tablets, etc.). Hence, testing your website & web applications across various combinations of browsers, platforms, and devices is very critical for your business as any inconsistency in the functionality could create a negative impression on user-experience and the business. The process of testing across different combinations is termed as ‘Cross-Browser Compatibility Test. What Is Cross-Browser Testing? Cross-Browser testing is a process of verifying the functionality of a website or web application across a different combination of browsers, in order to maintain ‘consistency’ in the functionality & quality. Cross-Browser testing is applicable for customer-facing websites and web applications. In some cases, it is also applicable for sites that are used internally in an organization e.g. intranet-based site that has email, ERP, and other common functionalities that are widely used in many organizations. Some developers limit the access to their web product, by permitting web-browsers through a user-agent. User-agent are responsible for retrieving, rendering, and facilitating the end user interaction with the web content. Why Cross Browser Testing Is Imperative? If you are building a global product i.e. consumers of your product also belong to emerging economies where there is still lower penetration of smartphones, there is a possibility that they might be using devices with an outdated version of the browser on the phone/tablet. Even on desktops, many users might be using older version of their favorite browser and these browsers may not support latest CSS, HTML5, JavaScript features. This could result in breakage of an important functionality on your website since these are preliminary languages used in web development. There are a huge number of phones, tablets, and smart TVs from different OEMs and each cater to different customer segments. They would have different RAM, ROM configurations, and variable screen sizes. Your website/web app on a low-end smartphone should accommodate all these requirements in order to keep up with its usability factor. As per a report from WHO, there are an increasing number of users who use assistive technologies to access the web. You need to ‘enable’ this user segment in case they are also the intended users of your web product. However, there lies a huge underlying challenge in testing your website/web app on a combination of different browsers and platforms. Hence, there should be a fallback mechanism for users who do not have latest browsers so that they can still access the sub-functionalities/sub-features if the ‘core functionalities’ are accessible. While developing the product, you can detect the ‘browser type’ by checking the ‘user agent’ and based on the (browser type browser version), come up with ‘stripped down features’ to accommodate the older version of the browser. As a developer, it seems impossible to have your website/web app ‘fully functional’ across all the browsers as there would certainly be a ‘category of miniscule number of users’ who might be using a browser from a relatively new company (having less market share) or using a very old version of a popular browser. Hence, you need to ensure that your product is functional on ‘an acceptable number of web browsers’ and decide ‘the acceptable number of browsers’ after having discussion with your product, development, and test teams. Cross-Browser Testing Cycle ‘Testing’ is a very important phase as fewer bugs in the end-product results to a better user experience.  » Read More
