Episode 87 of Software Testing with Fexingo dives into visual regression testing—why pixel-perfect UI checks catch bugs that traditional assertions miss. Lucas and Luna walk through a real-world case: a major e-commerce app that broke its checkout button in a routine CSS update. Automated snapshot diffs caught the issue before any customer hit a broken flow. They contrast tools like Playwright screenshots with dedicated platforms like Percy, and explain how threshold-based diffing prevents false alarms from intentional layout changes. The episode also touches on cross-browser visual testing—how Chrome and Firefox render a button differently—and why visual coverage should focus on high-traffic user journeys, not every page. A practical, example-driven look at a technique that many teams skip until it's too late. #VisualRegressionTesting #UIQuality #SnapshotDiff #Percy #Playwright #CSSBugs #CrossBrowserTesting #PixelPerfect #TestAutomation #FrontendTesting #E2ETesting #SoftwareTesting #QATechniques #FexingoBusiness #BusinessPodcast #TechPodcast #ReliableSoftware #RegressionTesting Keep every episode free: buymeacoffee.com/fexingo
