Posted on 

A seamless online experience is crucial for retaining users and driving business growth. Web browsers in particular are diverse. Each has unique features and functions, among other capabilities. That can present a challenge for developers striving for cross-browser compatibility. Browser popularity is not always the biggest driver. Desktop computers are an easy starting point for most users. Depending on the app, website, or digital service in development, however, compatibility in other areas could be more important. A large percentage of a business’s consumers might use mobiles over desktops. Testing across a wide range of browsers, platforms, screen sizes, and devices expands usage to the largest number of users. Let’s delve into the intricacies of browser compatibility testing in 2023. We’ll also explore how turning to QA professionals can strengthen front-end web designs.

The Challenges of Web Browser Testing

Browser incompatibility remains a concern for developers and users alike. A well-crafted website or mobile application can lose its impact if it doesn't function across various browsers. Users encountering broken layouts or non-functional features might quickly lose patience. That could result in lost engagement and revenue.

Time, a precious resource for developers, often gets consumed by cross-browser testing. Navigating through a myriad of browsers, versions, and devices to identify and fix compatibility issues can be time-consuming. Investing significant hours in manual testing, especially with a deadline, can hinder development progress.Manual testing on devices for frontend errors continues to be an excellent way to see how users would view your app, website, or product.

A common question that arises during web testing is, "Which browser should I use?" Browser market shares shed light on user preferences. But it's essential to consider the characteristics of your target audience. If your user base is primarily Chrome users, prioritize testing on Chrome. But don't neglect other browsers.

Best Practices for Web Browser Testing

Addressing browser incompatibility requires a strategic approach. Developers should consider the following strategies to mitigate challenges:

Responsive Design: Adopting responsive design practices ensures that your website adapts seamlessly to various screen sizes and resolutions. Responsive design can boost the user experience across browsers.

Regular Updates: Stay informed of browser updates and changes in rendering engines. Regularly testing your website against the latest versions of major browsers helps uncover compatibility gaps early on.Mobile Platform Usage: Similar to how users are looking at devices on various screen sizes, they also use various platforms. Android 10 is currently the most popular platform due to Google’s popularity. On the other hand, it’s important to understand what the user demographic of your app, website, or product will use most. Region-Specific: Consumers have vastly different online habits depending on location. While the majority of the world has navigated to Chrome, that may not be true for all users. You could find a high percentage of consumers use different browsers based on that alone.

Accessible Browser Features: All organizations should be aware that 1 out of 6 people in the world have a disability. Some users may need the assistance of devices and features for accessibility, such as screen readers, high contrast mode, and closed captions. It’s important to understand those features in the browser you are testing. And that your hardware or software is compatible with them.
