Cross-browser testing is the process of testing a website on several browsers, such as IE, Chrome, and Firefox, to determine its efficacy in each. Cross-browser compatibility refers to the capability of a website or web-based application to function across different browsers and operating systems. This blog will explore best practices for performing Cross-Browser Testing in Selenium. Selenium Training in Coimbatore provides a comprehensive understanding of all Selenium concepts.
However, manually testing a website across several browsers takes a lot of work. Consider the following scenario: 100 test cases must be run manually. Suppose the same tests must be performed on five distinct browsers. The time required increases dramatically. However, if the same tests are automated with Selenium, they can run concurrently and in less time. It will also prevent any problems caused by human error.
Why Is Cross-Browser Testing Important?
While browser vendors adhere to Open Web Standards, they often implement their interpretations. As a result, they render HTML, CSS, and JavaScript in distinctive ways. More than merely debugging a website’s source code is needed to ensure that the site will display and function correctly on various browsers or even different versions of the same browser.
As a result, web developers must abstract browser differences. Cross-browser compatibility testing helps identify browser-specific compatibility issues so that they can be debugged quickly. It ensures that a site does not alienate a significant portion of its target audience simply because the website does not work on their browser or OS.

Best Practice for Cross-Browser Testing in Selenium
Choose Libraries and Frameworks Carefully
When testing web applications, it’s crucial to consider the libraries and frameworks you intend to use. While the latest CSS frameworks can enhance the visual and dynamic aspects of the user experience, it’s important to note that they may not be compatible with every browser, given that each browser employs its unique rendering engine. Therefore, before incorporating the newest CSS or JavaScript libraries and frameworks into your project, it’s advisable to consult browser guidelines to ascertain whether they are supported by the browsers you plan to target.
Use Proper JavaScript Libraries and Task Runners
Utilize the appropriate JavaScript resources that meet site requirements and provide suitable browser compatibility, as JavaScript is an important component of web app development.
There is a variety of alternatives available for task runners. Grunt and Gulp are unique because they can be customized to automate requirements-based tasks. By offering abilities like compilation, linting, minification, and others that increase code quality after compilation, they also improve the overall efficiency of the application.

Carefully Identify and Analyze the Browser-OS Configuration
The browsers and operating systems that a website needs to be tested on must be determined by QAs. Each browser has several versions, and some even receive regular updates—at least once a month. Therefore, to conduct cross-browser testing using Selenium, it is vital to confirm which browser, browser versions, and OS are required. Give top priority to the combinations that most of the intended audience will most likely utilize.
Optimize Internet Explorer
Internet Explorer does not support advanced CSS styles and frameworks. Even if a site is visually stunning, many design features will be deformed when accessed with IE. To fix this, create a separate stylesheet for Internet Explorer and include a hack in the doctype.
