Demander un auditStep 1: Representative Scoping
An enterprise audit does not require testing all 50,000 pages of a website. It requires sampling every distinct page template, authenticated state, modal dialog, interactive component, and critical conversion pathway (login, search, checkout, file upload, form submission).
Step 2: Full Keyboard Navigation
Disconnect your mouse and navigate through the entire interface using only Tab, Shift+Tab, Enter, Space, Escape, and arrow keys. Check for visible focus indicators, logical focus order, modal focus traps, and bypass blocks (skip links).
Step 3: 400% Zoom and Reflow
Set browser zoom to 400% at a 1280px desktop resolution (simulating a 320px mobile viewport). Verify that content reflows into a single column without requiring horizontal scrolling (WCAG 2.2 SC 1.4.10) and that fixed navigation bars do not obscure reading content.
Step 4: Screen Reader Inspection
Launch NVDA on Windows or VoiceOver on macOS. Navigate by headings (H), landmarks (D), links (K), and form fields (F). Verify that custom components accurately convey their role, name, state (expanded/collapsed), and dynamic alerts.
Step 5: DOM & Accessibility Tree Inspection
Use browser DevTools Accessibility Tree to confirm that semantic roles are properly exposed to the operating system accessibility API without redundant or conflicting ARIA overrides.
