Cross Browser Testing: Strategies for Ensuring Consistent User Experience
Testing a website across various browsers and their versions is essential for providing users with a smooth and positive experience, regardless of their chosen browser. Browser compatibility extends beyond visual consistency; it impacts all aspects of user interaction on a site.
Whether it’s simple navigation or more complex actions like form submissions or media playback, cross-browser testing ensures a seamless and intuitive experience. Achieving full cross-browser compatibility is vital for a robust user experience. In this article, we’ll discuss cross-browser testing and strategies to ensure an excellent user experience.
Understanding Cross-Browser Testing?
Cross Browser Testing, also known as Browser compatibility, involves assessing if a web application’s performance remains the same when accessed from various browsers by the end user. It is additionally utilized to verify the compatibility of browsers for desktop and web applications. Cross-browser testing is a form of nonfunctional testing that allows websites to be efficiently tested on various browsers.
Why Cross-Browser Testing?
Imagine you’re diving into a website that claims to have every Bongo cat meme ever created. You’re trying this out for the first time on your brand-new MacBook Air.
You open Safari, type in the URL, hit Enter, and wait. When the site loads, you’re greeted with broken GIFs, scattered buttons, and misplaced text. You check your internet connection and refresh the page, but it’s still a mess.
At this point, you might think the site is down and come back later or assume it’s just broken and look for another meme haven.
Even though browser makers follow Open Web Standards, each has its own way of interpreting them. Since browsers render HTML, CSS, and JavaScript differently, just debugging your website’s code isn’t enough to ensure it works correctly across all browsers or even different versions of the same one.
That’s where cross-browser testing comes in. It identifies compatibility issues specific to different browsers, allowing you to fix them quickly. This way, you avoid losing potential users simply because your site doesn’t function properly on their browser or operating system.
What Aspects Are Tested in Browser Compatibility?
While compatibility testing covers a wide range of elements, time constraints often mean focusing on key areas.
To manage this effectively, product teams use a test specification document (test specs) that outlines essential aspects—such as features to test, the browsers, versions, and platforms involved, test scenarios, timelines, and budget.
Here’s how you might break down the features to be tested:
- Base Functionality: Ensures core functions work across various browser and OS combinations. This might include:
- Verifying that all dialog boxes and menus operate correctly.
- Checking that form fields accept and validate inputs properly.
