Visual Testing Skill
Perform visual testing, UI verification, and design comparison using screenshots, responsive testing, and Figma integration.
When to Use
This skill activates when:
- User wants to verify UI appearance
- User asks to compare page with design or Figma
- User needs responsive design testing
- User wants to check for visual regressions
- User mentions UI bugs or styling issues
- User asks about design parity
- User wants to validate implementation against design

Prerequisites for Figma Comparison
Figma API Access:
- Set
FIGMA_ACCESS_TOKEN environment variable
- Get token from Figma account settings
Optional (for enhanced comparison):
- AWS credentials for image/text embeddings
- Cloud inference profile configuration
Visual Testing Workflow
SESSION="--session-id visual-test"
ironbee-browser-devtools-cli $SESSION navigation go-to --url "https://example.com"
ironbee-browser-devtools-cli $SESSION sync wait-for-network-idle
ironbee-browser-devtools-cli $SESSION content take-screenshot --name "desktop"
ironbee-browser-devtools-cli $SESSION interaction resize-viewport --width 375 --height 667
ironbee-browser-devtools-cli $SESSION content take-screenshot --name "mobile"
ironbee-browser-devtools-cli $SESSION interaction resize-viewport --width 768 --height 1024
ironbee-browser-devtools-cli $SESSION content take-screenshot --name "tablet"
ironbee-browser-devtools-cli session delete visual-test
Figma Comparison Workflow
1. Get Figma Reference
Find the Figma file key and node ID:
- File key: From URL
figma.com/file/{FILE_KEY}/...
- Node ID: Select frame → Copy link → Extract node-id parameter
2. Compare with Live Page
ironbee-browser-devtools-cli figma compare-page-with-design \
--figma-file-key "ABC123xyz" \
--figma-node-id "12:34" \
--selector ".hero-section"
3. Analyze Results
- Score 0.9-1.0: Excellent match
- Score 0.7-0.9: Minor differences
- Score 0.5-0.7: Significant differences
- Score < 0.5: Major mismatch
4. Investigate Differences
If score is low:
ironbee-browser-devtools-cli content take-screenshot --name "mismatch" --selector ".hero-section"
ironbee-browser-devtools-cli content get-as-html --selector ".hero-section"
Comparison Modes
Semantic Mode (Default)
- More tolerant of text/data differences
- Focuses on layout and structure
- Good for comparing sample vs real data
ironbee-browser-devtools-cli figma compare-page-with-design \
--figma-file-key "ABC123" \
--figma-node-id "1:2" \
--mssim-mode semantic
Raw Mode
- Stricter pixel comparison
- Expects near-identical output
- Good for static content
ironbee-browser-devtools-cli figma compare-page-with-design \
--figma-file-key "ABC123" \
--figma-node-id "1:2" \
--mssim-mode raw
Common Scenarios
Full Page Comparison
ironbee-browser-devtools-cli figma compare-page-with-design \
--figma-file-key "ABC123" \
--figma-node-id "1:2" \
--full-page
Component Comparison
ironbee-browser-devtools-cli figma compare-page-with-design \
--figma-file-key "ABC123" \
--figma-node-id "5:10" \
--selector ".card-component"
Responsive Testing with Figma
ironbee-browser-devtools-cli interaction resize-viewport --width 375 --height 667
ironbee-browser-devtools-cli figma compare-page-with-design \
--figma-file-key "ABC123" \
--figma-node-id "20:30"
Common Visual Checks
- Element visibility at breakpoints
- Text overflow and truncation
- Image aspect ratios
- Color and typography consistency
- Spacing and alignment
- Interactive state styling
Best Practices
- Use semantic mode for real data vs sample data
- Compare components not just full pages
- Test multiple viewports for responsive designs
- Document Figma references for CI/CD
- Set baseline scores for regression testing
- Review notes in response for signal details
- Take screenshots at key states (initial, hover, active)
