Question 4

How do Percy and SmartUI manage dynamic content and UI changes?

Accepted Answer

Both Percy and SmartUI have mechanisms to handle dynamic content and UI changes. But SmartUI takes this a step further with its AI-native SmartIgnore feature. SmartIgnore is a next-gen solution specifically designed for dynamic web apps and frequently updated content. It intelligently filters out minor, irrelevant visual changes, like shadows or anti-aliasing, that don’t impact the user experience. By distinguishing between significant changes and irrelevant shifts, SmartIgnore reduces false positives, ensuring that only the most impactful visual differences are flagged. This makes SmartUI's handling of dynamic content particularly effective, giving you greater confidence in your UI's visual integrity.

SmartUI provides more detailed test reports than Percy due to its advanced AI-native debugging and AI-native test analytics. SmartUI offers powerful features like SmartUI Snapshot, Builds Summary, Builds Trends, Screenshot Trends, and coverage insights for browsers, devices, and viewports. Additionally, its Copilot AI—an NLP-based tool—lets users ask questions and get insights post-test run, making it easier to understand complex issues. These advanced AI capabilities and detailed reporting features make SmartUI the better option for in-depth visual testing reports.
