🎨 Visual Comparison Areas

✅ Supported Comparisons

• ✅ Padding and margins
• ✅ Element positioning and alignment
• ✅ Background colors (hex, RGB, RGBA, HSL)
• ✅ Text colors
• ✅ Gradients (linear, radial)
• ✅ Box shadows
• ✅ Opacity/transparency
• ✅ Font family, size, weight
• ✅ Line height and letter spacing
• ✅ Text alignment and decoration
• ✅ Element width and height
• ✅ Border radius, width, color, style

🔧 Configuration Guidelines

Default Tolerance Thresholds

Spacing: 1px
Color: 3 RGB units
Size: 2px or 1%
Opacity: 5%
Font size: 1px
Border width: 0.5px
Border radius: 1px

Sensitivity Levels

• High (Strict): Brand-critical pages, design systems
• Medium (Default): Standard production comparisons
• Low (Lenient): Quick checks, dynamic content areas

Example Ignore Rules

/* Dynamic content */
.user-avatar, .timestamp, .random-content

/* Third-party widgets */
#chat-widget, .social-embed, iframe[src*="youtube"]

/* Animated elements */
.carousel, .slider, .animated-banner

📈 Testing Workflow

Phase 1: Setup & Configuration

1. Configure Figma API connection
2. Set tolerance thresholds
3. Define ignore rules for dynamic content
4. Select target browser and viewports

Phase 2: Core Functionality Testing

1. Execute TC-001 to TC-050 (functional tests)
2. Verify basic comparison accuracy
3. Validate report generation

Phase 3: Responsive Testing

1. Execute TC-090 to TC-118 (responsive tests)
2. Test at all defined breakpoints
3. Verify layout adaptations

Phase 4: Edge Cases & Negative Testing

1. Execute TC-051 to TC-089 (edge cases)
2. Execute TC-119 to TC-160 (negative tests)
3. Verify error handling

Phase 5: Validation & Reporting

1. Review all detected mismatches
2. Classify by severity (Critical/Major/Minor)
3. Generate final test report
4. Document any tool limitations encountered

🛠️ Tools & Technologies

Required

📝 Best Practices

1. Start with Public Pages: Test public-facing pages before authenticated areas
2. Control Test Environment: Use consistent browser, viewport, and network
3. Document Ignore Rules: Maintain clear documentation of what's being ignored and why
4. Regular Calibration: Review tolerance settings periodically
5. Complement with Other Tests: Use alongside functional, accessibility, and performance testing
6. Manual Review: Always review flagged mismatches; don't blindly trust automation
7. Version Control Designs: Keep Figma designs synced with code versions

🤝 Contributing

When adding new test cases:

1. Follow the existing numbering scheme
2. Include preconditions, test data, expected results, and priority
3. Update the test case summary table
4. Document any new limitations discovered
