Snapshot/Golden Tests

Create snapshot and golden tests that detect unintended output changes.

Test Creation Checklist

UI Snapshot Capture

• Capture visual snapshots for all component states (default, loading, error)
• Test across relevant viewport sizes and screen densities
• Include snapshots for light/dark themes and accessibility modes
• Verify interactive states (hover, focus, disabled, selected)
• Establish pixel tolerance thresholds for acceptable rendering variance

API Response Baselines

• Capture baseline responses for all endpoint success cases
• Record error response structures for each error category
• Snapshot pagination metadata and envelope format
• Verify header values and content-type consistency
• Test response format stability across API versions
