Automated accessibility scanners catch important issues but cannot see every real-world usability problem. A button can be technically marked up correctly while an illogical focus order still makes the experience difficult for keyboard users.

Navigate the full flow with a keyboard

Without using a mouse, move through navigation, forms, dialogs and interactive cards. Verify that focus indicators are visible, the order follows the visual flow and keyboard focus never gets trapped.

  • Test the page at 200% and 400% zoom.
  • Verify accessible names of form fields with a screen reader.
  • Ensure states are conveyed by more than color alone.
Accessibility testing should be a recurring part of development, not a separate final stage.
