In the modern digital world, websites are the primary means of communication for companies and businesses; therefore, it is crucial that the company ensures the website’s compatibility with different web browsers. Web clients are typically enabled to connect to the Internet through many browsers, each with its rendering engine, versions, and special characteristics.
Therefore, in order to achieve perfect usability, all platforms should be tested by web developers and quality assurance (QA) teams should take the test websites in different browsers. With the goal of giving a comprehensive overview of browser testing, this guide offers techniques, resources, and best practices to improve the efficiency of the procedure and the caliber of web applications.
Understanding Browser Compatibility
Browser compatibility, often used to refer to a website or web application’s ability to run cohesively and efficiently across multiple browsers, is a term used to describe the level of integration of a given site with web browsers. As for the various forms of browsers that are prevalent in the market, there are Google Chrome, Mozilla Firefox, Microsoft Edge, Apple Safari, and many others, which make it even more challenging to create cross-browser compatibility. It is seen that there are disparities regarding the rendering engines, the CSS support, the JavaScript interpretation, and HTML rendering that eventually lead to differences in the appearance and functionality of the web content across the browsers.
Importance of Browser Testing
There are various reasons why browser testing is so crucial to the web development and quality assurance process:
