Testing Procedures¶

Environment: Windows 10, Chrome/Firefox, NVDA screen reader

Test Case 1: Tab Navigation

1. Open FrameworksPage
2. Press Tab key repeatedly
3. Verify focus visible on each element:
   - Header navigation links
   - Skip to main content link (appears first)
   - Featured framework card
   - Each framework card in grid
   - Pagination buttons
   - Footer links

Expected: Focus ring visible, logical left-to-right, top-to-bottom flow

Test Case 2: Screen Reader Announcement

1. Open BlogPage with NVDA enabled
2. Navigate to featured articles section
3. Verify announcements:
   - "Navigation region"
   - "Main region"
   - "Heading, level 2, Featured Articles"
   - "Article"
   - Image alt text: "[Author] on [Topic]"
   - Link purpose: "Read [Title] on [Date]"

Expected: All content announced in logical order, link purpose clear

Test Case 3: Animation Behavior Across Input Methods

1. Open ArchitectureDesignsPage
2. For mouse users: Scroll down, observe staggered blueprint entry
3. For keyboard users: Tab down, verify focus visible during animation
4. Disable animations: Set OS to "Reduce Motion" → Reopen page
5. Verify: Animations disabled, content fully visible immediately

Expected: Animations play smoothly on mouse, don't interfere with tab order, respect OS preference

Automated Testing Tools¶

Tool 1: Lighthouse (Chrome DevTools)

# Run accessibility audit
1. Open Chrome DevTools → Lighthouse

Tool 2: axe DevTools (Browser Extension)

# Install: https://www.deque.com/axe/devtools/
# Test procedure:
1. Open page to audit
2. Click axe DevTools icon
3. Scan page
4. Review violations

Expected: 0 violations at WCAG 2.1 Level AA

Tool 3: NVDA Screen Reader Compatibility

# Windows testing:
1. Download NVDA: https://www.nvaccess.org/
2. Enable NVDA
3. Tab through FrameworksPage
4. Press Arrow keys to read content
