Use visual regression testing
SkillDev toolsVisual regression testing is a skill that guides an AI agent through checking whether visual changes to web pages are caught by automated screenshot tests. It helps review CI coverage, automated checks, and test strategy, focusing on whether the rule is continuously verified rather than just documented.

Then ask your AI: use the Use visual regression testing skill
What your AI can do with it
- Guides review of CI coverage for visual regression testing
- Checks that automated screenshot tests catch visual changes to web pages
- Evaluates whether visual rules are continuously verified, not just documented
- Supports review of automated checks and test strategy
Getting started
- Have an AI agent that can load skills.
- Add the visual-regression skill to the agent's available skills.
- Ask the agent to review your CI coverage or test strategy for visual regression testing.
- The agent will check whether visual changes are caught by automated screenshot tests and whether the rule is continuously verified.
What this skill tells your AI
The instructions your AI receives, as published by thedaviddias/front-end-checklist in skills/visual-regression/SKILL.md and read by ahel’s review.
Functional tests verify behavior but don't see your page. A CSS refactor might pass all unit and integration tests while completely breaking the layout — text overlapping images, buttons invisible, wrong colors. Visual regression testing acts as a safety net that reviews your actual rendered output, catching changes that no amount of JavaScript testing can detect.
Quick Reference
- Visual regression tests catch CSS regressions that functional tests miss
- Run screenshot comparisons in CI to block merges that break visual appearance
- Use component-level (Storybook) tests for focused, fast visual coverage
- Set pixel difference thresholds to avoid flaky tests from sub-pixel rendering
Check
Does this project have visual regression testing? What critical components or pages would benefit most from visual baselines?
Fix
Set up visual regression tests for the key components using Playwright's screenshot comparison or a tool like Chromatic.
Explain
Explain visual regression testing, how it differs from functional tests, and how to set up screenshot comparison in a CI pipeline.
Code Review
Review tests, CI workflows, and enforcement points related to Use visual regression testing. Flag exact gaps where the rule is not automatically verified or where failures do not block regressions.
