SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires playwright, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill automates the detection of visual regressions in user interfaces, ensuring that UI changes do not introduce unintended visual discrepancies between development and release.

Core Features & Use Cases

  • Automated Screenshot Walkthroughs: Captures screenshots of UI flows during development for documentation.
  • Visual Diffing: Compares screenshots between different release versions to identify visual changes.
  • AI-Powered Classification: Uses a sub-agent to classify detected visual changes as expected or unexpected, prioritizing review.
  • Use Case: After updating the styling of a product page, run this skill to compare the new version against the previous release, automatically flagging any layout shifts or incorrect element rendering.

Quick Start

Run the visual-regression skill in compare mode between tags v1.2.0 and v1.3.0 to generate a report of visual changes.

Frequently Asked Questions about visual-regression

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I automate visual regression testing to catch UI bugs?▼

Visual regression testing detects unintended UI discrepancies by capturing screenshots during development and comparing them between different release versions. It utilizes Playwright to generate screenshots and a sub-agent to classify whether visual changes are expected or unexpected.

How do I compare UI screenshots between different release versions?▼

To compare UI screenshots between release versions, run a visual regression skill in compare mode between two tags, such as v1.2.0 and v1.3.0. This generates a report of visual changes, flagging any incorrect element rendering or layout shifts for review.

Does visual regression testing work with Playwright for screenshot generation?▼

Yes, visual regression testing works directly with Playwright for screenshot generation. Playwright automates the screenshot walkthroughs of UI flows, providing the baseline images required for diffing and subsequent AI-powered classification of visual changes.

How are visual differences classified during automated UI testing?▼

Visual differences are classified during automated UI testing using an AI-powered sub-agent. After screenshots are compared between code versions, the sub-agent analyzes the visual diffs and categorizes them as expected or unexpected, prioritizing high-risk changes for human review.

What is the best way to detect unintended layout shifts before a release?▼

The best way to detect unintended layout shifts before a release is to run automated visual diffing against the previous version. By capturing screenshots of UI flows and applying AI classification, you automatically flag incorrect element rendering for review.
