Visual regression testing automatically compares current screenshots against golden-file references to detect UI inconsistencies. This Skill runs test scenarios in UI-stripped mode, captures 1280x960 renders with deterministic seeds, and generates diffs to identify visual regressions before they reach production.

Golden files are committed reference screenshots representing the expected UI state. Current outputs are fresh renders from test scenarios. Comparing them reveals whether recent code changes altered the UI visually—changes flagged as regressions or intentional updates.

Execute run_tests.sh to generate current outputs, compare_golden.sh to detect differences against golden files, and report_bug.sh to create structured bug reports. The Skill generates diffs via ImageMagick when available, making regressions visible and traceable.

Yes. This Skill integrates into CI workflows by automating test execution, golden-file comparison, and diff generation. Run tests on every commit to catch visual regressions early, ensuring UI consistency across builds without manual screenshot review.

ImageMagick is optional but enables diff generation for visual comparison. Without it, the Skill still detects differences between current and golden files; diffs simply won't render as images. Install ImageMagick for visual diff output in reports.

Update golden files when UI changes are intentional—new designs approved and ready to commit. Report visual regressions as bugs when changes are unintended or break existing functionality. Use update_golden.sh for approved changes and report_bug.sh for unexpected deviations.
