Automated Visual Regression Testing
Protect your design system from unintended visual changes by adding automated visual regression testing to your tooling and CI pipeline.
The Hidden Risk of Visual Drift
Unit tests catch logic bugs, but a one-line CSS change can silently break the look of dozens of components. Visual regression testing catches these invisible-to-code changes.
This lesson adds a critical safety net to your design system infrastructure.
How It Works
Visual regression testing captures a baseline screenshot of each component. On every change, it captures a new screenshot and compares pixel-by-pixel.
If pixels differ beyond a threshold, the test flags it for human review.
