Use when setting up visual regression testing with Playwright - toHaveScreenshot baselines, masking dynamic content, handling animations, full-page and element screenshots, cross-browser runs, CI integration, VUDA MCP tooling, or debugging flaky visual diffs.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
> **Objective:** Use this skill to prevent flaky visual regression tests and missed UI regressions by enforcing baseline discipline, dynamic content masking, and CI integration patterns below. # Playwright Visual Regression Testing Complete guide to visual regression testing using Playwright's built-in `toHaveScreenshot()` API, VUDA MCP integration, and AI-powered visual analysis with vision models. ## Overview Playwright provides native visual regression testing through the `toHaveScreenshot()` assertion. It captures screenshots, compares them against baselines using pixelmatch, and fails tests when visual differences exceed configured thresholds. **Key Features:** - Built-in screenshot comparison (no external dependencies) - Pixel-by-pixel comparison with configurable thresholds - Dynamic content masking - Animation handling - Cross-browser testing (Chromium, Firefox, WebKit) - Full-page and element-level screenshots - Integration with VUDA MCP for AI-powered visual debugging - Vision model integration for screenshot analysis ## Installation ### Python Installation ```bash # Install Playwright for Python pip install playwright # Install browser drivers …

How to install
mdr add codeatcode/oss-ai-skills/playwright-visual-regression@sha256:22d136e416d97362The line at the top of this page pins the label v2.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
