While about half of users will be on the popular, low-risk browsers that developers use such as Chrome and Firefox, the bugs will mainly be saturated in high-risk browsers like Internet Explorer. "It works on my machine" is not a valid argument. However, a misconception is that another user will be visiting the same website on the same browsers and devices. Layout, accessibility, connectivity, quality, and performance can vary slightly or exponentially from browser to browser, as each renders CSS, HTML, and JavaScript differently.ĭevelopers inherently know and learn the lowest risk browsers and devices, and in turn, use them every day to view the product of their coding.

Meanwhile, each browser responds to these code changes differently, and so with every change of code comes a risk that any of those browser/device/OS combinations may not respond according to expectations. Developers are no longer making yearly updates but instead instituting continuous integration with updates by the hour or day. Furthermore, to parallel the rise of mobile and desktop internet consumption, design and development have moved to an agile methodology. Times have changed, however, and today’s consumers are on a multitude of devices ranging from desktop computers and laptops to mobile phones and tablets, while there are too many browsers and browser versions to count at this point. Additionally, with a waterfall model design process where developers were primarily making quarterly or monthly changes to code, manually testing each one was relatively simple. There used to be only a handful of browsers existing across the internet, and they were mainly situated on desktops. Understanding the many factors can exponentially impact your web application and increase customer satisfaction while ignoring its importance can have a negative effect on reputation and bottom line goals. While fundamentally self-explanatory, browser testing has an expansive amount of components. On top of that, screen size, screen resolution, OS version, and browser versions all change and contribute to how someone is viewing content, making the practice of cross-browser testing increasingly necessary for understanding diversified user experiences. It’s implemented to ensure a website’s functionality and design and includes testing a range of devices and operating systems being used in the market and customer base. That is to say, it ensures the quality of your website on different screens.
Browser testing is a method of quality assurance for web applications across multiple browsers.
