Improving Cross-Browser Compatibility for a CMS Solution through Comprehensive Compatibility Testing

Client Overview:

A leading digital agency specializing in content management systems (CMS) approached SDET Tech, a top-tier software testing company in India, to improve cross-browser compatibility for their flagship CMS solution. The CMS had issues rendering consistently across various browsers and devices, resulting in poor user experience for their clients.

Challenges:

1. Inconsistent Rendering: The CMS had inconsistencies in its UI when accessed through different browsers like Chrome, Firefox, Safari, and Edge. The CSS, JavaScript, and HTML elements behaved differently, leading to user frustration.

2. Performance Issues on Older Browsers: The CMS struggled with performance on older browser versions that many of the client’s users still relied on.

3. Mobile Compatibility: The client needed assurance that the CMS would work seamlessly on mobile browsers as well as desktop versions.

Solution Provided by SDET Tech:

SDET Tech developed a comprehensive cross-browser compatibility testing strategy to ensure the CMS worked uniformly across all browsers and devices.

1. Test Environment Setup:

• Browser Matrix Selection: SDET Tech selected a browser matrix based on the client’s user analytics data, which identified the most used browsers, their versions, and operating systems (OS). This included desktop browsers (Chrome, Firefox, Edge, Safari) and mobile browsers (Android, iOS).
• Cloud-based Testing Tools: Leveraging cloud platforms like BrowserStack, SDET Tech created virtual environments that simulated real-world usage of multiple browsers, devices, and operating systems.

2. Automation Testing:

• Selenium Automation Framework: SDET Tech used Selenium to automate regression tests across different browsers, ensuring consistent UI/UX. This reduced manual testing time significantly while maintaining high test coverage.
• Test Scripts for Responsive Design: Custom scripts were written to ensure the CMS responded effectively across varying screen sizes, especially on mobile browsers.

3. Manual Testing:

• Edge Case Validation: A specialized QA team manually tested on older and less popular browsers, validating edge cases where automated tests may fall short. This included browsers such as Internet Explorer 11.
• Mobile Device Testing: SDET Tech’s testers performed manual tests on popular mobile devices like iPhones and Android smartphones, ensuring the CMS’s responsiveness.

4. Defect Management and Reporting:

• Bug Tracking: Using Jira, SDET Tech meticulously tracked all issues found during compatibility testing. Bugs related to CSS inconsistencies, JavaScript errors, and performance issues were prioritized.
• Collaboration with Development Team: The QA and development teams worked in tandem to resolve these issues quickly and efficiently, with daily stand-ups and regular feedback loops.

5. Performance Testing:

• Optimization for Older Browsers: SDET Tech performed load and performance tests specifically targeting older browser versions. They identified JavaScript libraries and CSS rules causing slowdowns and recommended optimizations, allowing the CMS to run smoothly even in outdated environments.

6. Final Regression Testing and Certification:

• Once the fixes were implemented, SDET Tech conducted final regression tests, validating that the CMS now worked flawlessly across all targeted browsers. The CMS was certified as cross-browser compatible, delivering a seamless user experience.

Results:

• Improved User Experience: Post-testing, the client reported a significant improvement in user experience across all browsers, leading to positive customer feedback.
• Faster Load Times: Optimizations for older browsers reduced page load times by 30%, improving performance across the board.
• Reduced Maintenance Costs: The automation scripts provided by SDET Tech allowed the client to perform future compatibility tests with minimal effort, reducing ongoing maintenance costs.

Conclusion

Through SDET Tech’s comprehensive compatibility testing strategy, the client was able to deliver a consistent, user-friendly CMS solution across various browsers and devices. This case highlights how software testing companies in India, like SDET Tech, can deliver high-quality solutions that enhance user experience and drive business success.
