The key things are knowing what browsers to test, planning out what to test, actually doing the testing, and documenting any issues found to fix later.

Addressing Common Compatibility Issues

Despite your best efforts, you may come across common cross-browser compatibility issues. Here’s how to tackle them:

  • CSS Interpretation:

Browsers may interpret CSS differently, causing variations in your website’s appearance. To ensure consistency, use a CSS reset to override default browser styles. Additionally, consider using browser-specific stylesheets or CSS features like Flexbox and Grid for more uniform layouts.

  • JavaScript Functionality:

JavaScript adds interactivity to your site, but browsers may interpret it differently. Use feature detection and polyfills to ensure your JavaScript works across browsers. Test your code in various browsers to catch any discrepancies.

  • HTML Rendering:

Browsers can render HTML differently, affecting your site’s structure and layout. Validate your HTML to identify and fix issues. Utilize HTML5 semantic elements for a more consistent structure across browsers.

Using automatic testing tools makes checking websites on multiple browsers and devices much more efficient. It frees developers from tedious manual testing so they can spend time on other essential tasks.

  • Develop a Channel for Code Validation:

Creating a channel for code validation is essential to uphold cross-browser compatibility. Adhering to W3C standards in the website or application code reduces the likelihood of compatibility issues stemming from syntax errors or non-standard practices. Establishing a process for code validation can include integrating validation tools into the development workflow or implementing a dedicated code review procedure. This ensures the identification and resolution of compatibility-related concerns early in development.

  • Implement Retest and Regression Testing:

As changes and updates are introduced to the website or application, it is essential to establish a retest and regression testing channel. The website should be retested across the defined browser and device matrix to identify and address potential compatibility problems whenever new features or modifications are made. This proactive approach helps maintain a consistent user experience and prevents compatibility issues from persisting or resurfacing.

Conclusion

Determining which browsers to test is not solely based on research; it relies on the preferences of your target market.
