Testing & Validation

Checking your content's accessibility can be easier using validation tools.

Keyboard Navigation

For Web Developers

• Ensure all interactive elements are reachable by keyboard alone.
• Verify a logical tab order and visible focus indicators.
• Ensure the element is usable once in focus.
• Test for complete functionality using only a keyboard.

Text Magnification

For Web Developers

• Allow users to zoom text up to 200% without loss of functionality or readability.

Screen Reader Testing

• Ensuring digital accessibility means creating websites and web applications that are usable by everyone, including individuals who rely on screen readers due to visual impairments or other disabilities.
• Screen readers convert on-screen content into synthesized speech or Braille output, allowing users to navigate digital content without relying on visual cues. If a site isn’t properly structured or marked up, screen readers may misinterpret or skip important information, creating major barriers to access.
• Effective screen reader testing helps identify and fix issues that could make your content confusing, incomplete, or entirely inaccessible to users with disabilities. This ensures compliance with accessibility standards like WCAG (Web Content Accessibility Guidelines).

Built-in Screen Reader Tools

• Windows Narrator
• VoiceOver for macOS

Best Practices for Screen Reader Testing

• Use multiple screen readers and browsers to understand differences in how content is interpreted.
• Test all interactive elements, including forms, buttons, and navigation menus.
• Ensure that headings, landmarks, labels, and alt text are present and meaningful.
• Avoid relying solely on visual cues such as color or layout.
