What accessibility tests are needed for video platforms?

Video platforms require accessibility testing across five areas: keyboard navigation (all controls reachable without a mouse), screen reader compatibility (ARIA labels, focus management, announcements), closed captions (accuracy, timing, positioning), color contrast (WCAG 2.1 AA minimum 4.5:1 ratio for text), and audio descriptions (for visual-only content). WCAG 2.2 adds additional criteria around focus appearance and dragging movements that affect interactive video controls.

What is WCAG 2.1 compliance testing?

WCAG 2.1 defines three levels of accessibility conformance: A, AA, and AAA. Most legal and regulatory requirements target AA compliance. Testing for WCAG 2.1 AA involves validating perceivability (captions, contrast, text alternatives), operability (keyboard access, no seizure-inducing content), understandability (readable content, predictable behavior), and robustness (compatibility with assistive technologies like screen readers and switch devices).

What tools are used for accessibility testing?

Accessibility testing combines automated scanning tools and manual validation. Common tools include axe-core and Lighthouse for automated checks, NVDA and JAWS for Windows screen reader testing, VoiceOver for macOS and iOS, and TalkBack for Android. Automated tools catch around 30-40% of WCAG issues - the rest require manual testing by QA engineers who simulate real assistive technology usage.

How long does accessibility testing take for a video platform?

A focused WCAG 2.1 AA audit of a video platform covering core user journeys typically takes one to two weeks for an experienced QA engineer. Full compliance testing including multiple assistive technologies, device types, and edge cases runs two to four weeks. For platforms undergoing ongoing development, integrating accessibility checks into each sprint prevents regression and keeps the compliance baseline stable.
