# Visual Regression Tester
## Overview
Detect unintended visual changes in UI components by capturing screenshots and comparing them pixel-by-pixel against approved baselines. Supports Playwright visual comparisons, Percy, Chromatic, BackstopJS, and reg-suit.
## Prerequisites
- Browser automation tool installed (Playwright, Puppeteer, or Cypress)
- Visual regression library configured (Playwright `toHaveScreenshot`, Percy, Chromatic, or BackstopJS)
- Baseline screenshots committed to version control or stored in a cloud service
- Storybook or component playground running for isolated component captures (optional)
- Consistent rendering environment (Docker or CI with fixed OS/fonts/GPU settings)
