Setup Visual Testing

Setup comprehensive visual regression testing with responsive and accessibility validation: $ARGUMENTS

Current Visual Testing Context

• Frontend framework: !grep -l "react\\|vue\\|angular" package.json 2>/dev/null || echo "Detect framework"
• UI components: !find . -name "components" -o -name "src" | head -1 && echo "Component structure detected" || echo "Analyze structure"
• Existing testing: !find . -name "cypress" -o -name "playwright" -o -name "storybook" | head -1 || echo "No visual testing"
• CI system: !find . -name ".github" -o -name ".gitlab-ci.yml" | head -1 || echo "No CI detected"

Task

Implement comprehensive visual testing with regression detection and accessibility validation:

Testing Scope: Use $ARGUMENTS to focus on component testing, page testing, responsive testing, cross-browser testing, or accessibility testing

Visual Testing Framework:

1. Tool Selection & Setup - Choose visual testing tools (Percy, Chromatic, BackstopJS, Playwright), configure integration, setup environments
2. Baseline Creation - Capture visual baselines, organize screenshot structure, implement version control, optimize image management
3. Test Scenario Design - Create component tests, design page workflows, implement responsive breakpoints, configure browser matrix
4. Integration Setup - Configure CI/CD integration, setup automated execution, implement review workflows, optimize performance
5. Regression Detection - Configure diff algorithms, setup threshold management, implement approval workflows, optimize accuracy
6. Advanced Testing - Setup accessibility testing, configure cross-browser validation, implement responsive testing, design performance monitoring

Advanced Features: Automated visual testing, intelligent diff analysis, accessibility compliance checking, responsive design validation, performance visual metrics.

Quality Assurance: Test reliability, false positive reduction, maintainability optimization, execution performance.

Output: Complete visual testing setup with baseline management, regression detection, CI integration, and comprehensive validation workflows.
