Testing Checklist
Once your environment is ready, use this checklist to ensure you’re covering all critical accessibility features:
1. Document Structure
Check that HTML language attributes and semantic markup are correct. Confirm the heading hierarchy flows logically from H1 to H6.
2. Navigation Elements
Test main navigation menus, skip links, and landmark regions. Ensure the keyboard focus is clearly visible and follows a logical tab order.
3. Content Components
Evaluate these key elements:
- Alt text and image descriptions
- Form labels and error messages
- Table headers and relationships
- Link purpose and clarity
- Updates to dynamic content
- Accessibility of modal dialogs and popups
4. Interactive Features
Ensure all interactive elements are keyboard-accessible, properly labeled, and provide clear feedback for state changes.
With this checklist, you’re ready to dive into detailed accessibility testing for your website.
Running Accessibility Tests
Now that your testing setup is ready, it’s time to assess your website’s accessibility using screen readers.
Navigation Testing
Check how users navigate your website using only a keyboard and screen readers.
| Navigation Element | What to Test | Success Criteria |
|---|---|---|
| Main Menu | Tab order, dropdown access | Clear focus indicators, proper announcements |
| Skip Links | Presence on the first tab stop | Announces "Skip to main content" |
| Interactive Elements | Buttons, links, controls | All elements are focusable and actionable |
| Focus Indicators | Visibility and contrast | Consistent and clear visual indication |
Heading Structure Review
Screen reader heading navigation helps ensure:
- There’s only one H1 heading per page.
- Headings follow a logical order.
- Section descriptions are accurate.
- Screen readers announce heading levels correctly.
Image Alt Text Testing
Verify that all images provide meaningful alt text or are ignored if purely decorative. Use screen reader commands to test:
- Informational images
- Complex visuals
- Image buttons
Form Testing
1. Label Association
Ensure every form field has a label that screen readers can announce accurately.
2. Error Handling
Submit incorrect data to confirm error messages are announced, focus shifts to the first error, and instructions for corrections are clear.
Dynamic Content Check
Test dynamic elements like modals and live updates to ensure they function well with screen readers. Key areas to evaluate include:
- Modal dialogs: Focus should remain trapped within the modal, and keyboard interactions should work seamlessly.
- Live updates: Use ARIA live regions to ensure updates are announced.
- Carousels: Verify keyboard control and the ability to pause.
- Expandable sections: Check that state changes are announced.
"Screen reader testing ensures users with visual impairments can access and navigate your website effectively, improving inclusivity." – Aayushi Verma, Community Contributor, BrowserStack [1]
Pair manual screen reader testing with tools like BrowserStack Accessibility Testing for a thorough evaluation. Automated tools alone may miss some issues [1][2].
After completing these tests, review the results to determine which issues to address first.
