E2E Test Plan

  • Setup:
    • Log in with a user that has appropriate permissions
    • Navigate to /risk
    • Ensure test data exists (scanned artifacts, SBOM data, or seed data as needed)
  • Core verification:
    • Verify the visualization renders correctly with sample data
    • Verify interactive elements (hover tooltips, click-to-drill-down) work
    • Verify the visualization handles empty/minimal data gracefully
  • Edge cases:
    • Verify graceful handling when backend API is unavailable (error state)
    • Verify responsive layout at different viewport sizes
    • Verify accessibility (keyboard navigation, screen reader labels, ARIA attributes)
