Web browsers are arguably the most widely used computer applications around the world. Web browser testing thus becomes a vital part of any browser transfer or upgrade process. This is our approach to web browser and compatibility testing.
Compatibility Testing: What does it mean?
Compatibility testing is done to evaluate the user’s visual experience and the functionality of a browser in different conditions. Browsers are essentially translators – they translate data from HTML into a formatted, discernable web page. Since each browser has a different process for this conversion, results of the same HTML data can slightly vary from browser to browser. Testing must be done to check the browser capability when data is converted. When faced with this problem we call upon our expert testing team, which consists of professionals who are thought leaders in fields like test strategy, compatibility testing, performance testing and test automation. Our testing is a mix of manual and automated, with a keen focus on real world user experience.
Compatibility Testing for Browser Upgrades
Browser manufacturers generally release upgrades on a fairly regular scale. Browsers like Chrome and Firefox go through a six week release cycle for their upgrades. Most of the usual upgrades include routine bug fixes, and it is fairly uncommon to see major browser upgrades in regularity. Nonetheless, when a browser does undergo a major facelift, like the transition from IE9 to IE10, rigorous testing is required on the interface and behavioral level. The HTML language is defined by the World Wide Web Consortium, and undergoes regular updating. The major difference between old and new versions from the same browser is support for the newer portions of HTML. At the same time, additional features like email integration, instant messaging and cloud support might be added. Sometimes, the browser GUI or design is upgraded, which changes its look and feel. In all these cases, testing is required to assess the usability and user experience of the browser, and whether the upgrade is capable of supporting web applications designed for the previous version of the browser.
Areas of Focus in Compatibility Testing
These are the general areas of focus while testing web browsers. It is not an exhaustive list, and additions and deletions are done to it on a case by case basis. But on the whole, these are the areas where compatibility testing is required during browser upgrades.
- Font size validation
- Date formats
- Special characters with HTML character encoding
