We are in the digital era, where every new web browser that launches with promises to blow our browsing experience comes with its set of features. The role of compatibility testing is This testing aims to check that a website provides a reasonably smooth user experience across browsers, so even the old ones like Internet Explorer (IE), which in its dwindling use and support still pose some unique challenges to web developers and software testers. However, while in dwindling use and support, Internet Explorer still poses a few unique challenges for web developers and software testers. This blog post will detail some of the best practices for Internet explorer online testing, covering challenges and solutions available, with a prime focus on tools like LambdaTest, which makes your lives easier.
The Significance of Testing on Internet Explorer
You might be wondering why we would test on Internet Explorer when the rest of the world has long moved on to faster, more secure browsers. The answer lies in a demographic still using IE: most of the world’s businesses, schools, universities, and government computer systems are written to work specifically with Internet Explorer. In any such case, it becomes essential for any developer or business that aims to serve such users to make sure that the websites work flawlessly on IE.
Though Internet Explorer’s market share has significantly dwindled, ignoring it could mean alienating a segment of users who, for various reasons, cannot or will not switch to modern browsers. This reality influences web development strategies, requiring a balanced approach that accommodates new technologies while ensuring backward compatibility.

Challenges in Internet Explorer Online Testing
Testing on Internet Explorer comes with challenges that can test the patience of even seasoned developers.
Browser Compatibility Issues
There are many sub areas of browser compatibility issues.
CSS Compatibility
The visual aspect of websites often goes awry in Internet Explorer, thanks to its notorious CSS compatibility issues. Styles that render perfectly in browsers like Chrome or Firefox may break in various versions of IE. This is partly because IE does not fully support modern CSS properties and features such as flexbox, grid, and CSS variables, which are staples in contemporary web design. Developers must resort to fallbacks or alternative strategies to ensure their site’s layout and design remain intact in IE. This often involves using older layout techniques like float-based layouts or even conditional CSS files specifically for IE.
JavaScript Performance
JavaScript, the backbone of web interactivity and functionality, also behaves unpredictably on IE. Scripts that are efficient and smooth in modern browsers can lead to crashes or significantly slow down the website in IE. This discrepancy arises from IE’s slower JavaScript engine and incomplete or incorrect implementation of modern ECMAScript standards. To tackle this, developers might need to transpile their JavaScript code using tools like Babel to convert modern JavaScript into a version that is compatible with IE. Additionally, polyfills can be used to emulate missing features, but they come with their own performance overhead.
HTML5 Elements
The adoption of HTML5 introduced a slew of semantic elements and APIs to enhance the web’s capabilities. However, IE’s limited support for HTML5 elements complicates web development, requiring developers to implement fallback solutions for basic functionalities like video playback and canvas drawings. This often means adding extra libraries or scripts to replicate the functionality available natively in other browsers, increasing the website’s load time and complexity.
Debugging and Developer Tools
Debugging in Internet Explorer can feel akin to navigating a maze without a map. The developer tools provided by IE are generally considered less user-friendly and less powerful than those in Chrome or Firefox. Features like live DOM editing, advanced JavaScript debugging, and performance profiling are either absent or not as sophisticated in IE. This lack of robust debugging tools makes identifying and fixing issues a more time-consuming and frustrating process. Developers often have to rely on console logs or alert messages to debug JavaScript issues, reminiscent of early web development days.
Security and Performance Concerns
Generally security and performance goes hand in hand and need some tradeoffs quite often.
Security Model: Internet Explorer’s security model, built for a different era of the internet, presents numerous challenges. Its outdated model does not adequately protect against modern web threats, making websites more vulnerable to attacks when accessed via IE. Developers must implement additional security measures and often need to design their applications with a “least privilege” principle, ensuring that IE’s limitations do not expose the website to unnecessary risks.
Performance Issues: Performance is another area where IE lags significantly behind its contemporaries. The browser struggles with rendering complex layouts, processing JavaScript efficiently, and managing modern web applications’ demands. These performance issues not only degrade the user experience but also complicate the testing process, as developers must find ways to optimize their sites specifically for IE. This might involve simplifying designs, reducing the use of heavy scripts, and optimizing images and other resources for faster loading times.
Best Practices for Internet Explorer Online Testing
Given these challenges, adopting certain best practices can make the process of Internet Explorer online testing more bearable and effective.
Graceful Degradation vs. Progressive Enhancement:
These approaches offer strategic methods for dealing with browser compatibility issues. Graceful degradation involves building your site for the latest browsers while ensuring it remains functional in older ones, albeit with some features disabled. Progressive enhancement, on the other hand, starts with a basic functional site on older browsers, gradually adding more features for browsers that can handle them. Both strategies are relevant for IE testing, depending on the project’s goals and audience.
Using Polyfills and Shims:
Polyfills and shims denote scripts developed by developers to deliver modern web functionalities to the most ancient browsers that never had anything of the native features in place. Including this in your project provides functionality in Internet Explorer that is otherwise not supported with newer browsers, so you have good backward compatibility between old and new.
Automated Testing Strategies:
Manual testing of this with different versions of Internet Explorer would be quite a pain and error-prone process. So, here, automation becomes very helpful in letting developers carry out the same very easily and faster across different IE versions. With automated tests, you can simulate all sorts of user interactions, ensuring your site works in IE without having to babysit it constantly.
Testing on Internet Explorer, despite its challenges, is a necessary step for ensuring that websites are accessible to all users, including those on legacy systems. By understanding the unique difficulties IE presents and implementing best practices like graceful degradation, using polyfills, and automated testing, developers can navigate these waters more smoothly.
