How Visual Regression Testing Catches Hidden Bugs

In this episode of Software Testing with Fexingo, Lucas and Luna explore visual regression testing — a technique that catches layout and styling bugs that functional tests miss. They break down how a major e-commerce company lost millions because a CSS change broke the checkout button on mobile devices, and how visual regression testing could have caught it before release. The hosts discuss threshold-based pixel diffing, tooling like Applitools and Percy, and the delicate balance between catching visual issues and managing false positives. They also touch on integrating visual tests into CI/CD pipelines and the importance of baseline image management. If you've ever pushed a UI change that looked perfect in your browser but broke in production, this episode gives you the framework to prevent it. #VisualRegression #Testing #Software #QA #Automation #CSS #UI #UX #Bugs #CI/CD #PixelDiffing #Applitools #Percy #Ecommerce #MobileTesting #Technology #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
