Accessibility Testing

Accessibility testing is the practice of evaluating a software application to ensure it can be used by people with disabilities, including those who rely on screen readers, keyboard navigation, voice controls, or other assistive technologies.

Understanding Accessibility Testing

Accessibility testing verifies that an application complies with standards like the Web Content Accessibility Guidelines and is usable by people with visual, auditory, motor, or cognitive disabilities. This includes checking for proper heading structure, sufficient color contrast, keyboard navigability, screen reader compatibility, and meaningful alt text for images.

AI code generation tools frequently produce inaccessible output. They may generate images without alt attributes, forms without proper labels, interactive elements that cannot be reached by keyboard, or color combinations that fail contrast requirements. The AI optimizes for visual appearance and functionality but rarely considers assistive technology compatibility unless specifically prompted.

Accessibility is not just about compliance or social responsibility. In many jurisdictions, digital accessibility is a legal requirement. Beyond legal obligations, accessible applications reach a wider audience and tend to be better designed overall. Testing for accessibility is a mark of quality that signals your application was built with care.

Example usage

Accessibility testing revealed that our entire navigation menu was invisible to screen readers because the AI used div elements instead of semantic nav and button tags.
