SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This Skill automates the process of taking screenshots of web applications, eliminating the need for manual capture and ensuring consistent visual verification.

Core Features & Use Cases

  • Automated Screenshots: Capture full-page or specific element screenshots of web pages.
  • Visual Regression Testing: Use screenshots to detect unintended UI changes.
  • Demo Page Verification: Capture the state of interactive demo components for review or documentation.
  • Use Case: After updating CSS styles, use this Skill to automatically generate screenshots of key demo pages to visually confirm that the layout and appearance are as expected.

Quick Start

Run the visual-test script to capture a screenshot of the 'cast-assignment' demo slide with debug markers enabled.

Frequently Asked Questions about visual-testing

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

FAQPage Schema
How do I automate screenshots for visual regression testing?▼

Capturing full-page screenshots with Puppeteer involves configuring viewport sizes and wait times for dynamic content rendering. The automation script targets specific demo pages or custom URLs to ensure consistent UI verification against a local development server.

Can I capture specific demo pages instead of a full website?▼

Yes, capturing specific demo pages is supported by configuring the Puppeteer script to target custom URLs or individual slides. This enables focused UI verification of interactive demo components instead of capturing the entire full-page view.

Does Puppeteer support configurable viewport sizes for UI verification?▼

Yes, Puppeteer supports configurable viewport sizes for UI verification to capture screenshots across different screen dimensions. This ensures the web application layout is visually verified under various display conditions using specified wait times.

Do I need a local development server to capture web application screenshots?▼

Yes, a local development server is required to capture web application screenshots because the Puppeteer automation integrates with it for dynamic content rendering. This integration ensures the captured screenshots accurately reflect the live UI state during visual testing.

What is the best way to verify CSS changes do not break existing UI layouts?▼

The best way to verify CSS changes do not break existing UI layouts is by capturing automated screenshots of key demo pages before and after updates. This visual regression testing approach detects unintended UI changes by comparing the rendered states.

Are there limitations when using Puppeteer for full-page screenshots?▼

Limitations when using Puppeteer for full-page screenshots include accurately capturing dynamic content that requires precise wait times. If wait times are misconfigured, the visual verification may capture incomplete UI state rendering during regression testing.
