Screen Reader Testing

A hands-on playbook for validating web accessibility with VoiceOver, NVDA, JAWS and TalkBack.

Dev & CodingIntermediate★ 40,179⑂ 4,286AI score 9/10Last updated: Oct 1, 2026

What it does

  • Maps the major screen readers (VoiceOver, NVDA, JAWS, TalkBack, Narrator) to platforms, browsers, market share and a recommended testing priority.
  • Lists the essential keystrokes for each tool — rotor, elements list, heading/form/landmark jumps — and explains browse vs focus mode.
  • Supplies checklists by area (page load, navigation, links, forms, dynamic content, tables) plus a step-by-step NVDA test script.
  • Shows broken-vs-fixed ARIA snippets and accessible patterns for modals with focus traps, live regions and tab interfaces.

Who it's for

  • Front-end developers, QA engineers and accessibility specialists
  • Teams preparing for WCAG conformance or public-sector/finance audits
  • SPA developers fighting focus-management and live-announcement bugs

Examples

  1. An icon-only button announces nothing useful → apply the aria-label + aria-hidden fix pattern.
  2. Before shipping a checkout form, run the NVDA script to verify labels, error announcements and focus movement.
  3. Wrap a dialog with role=dialog / aria-modal plus the focus-trap snippet, then verify against the VoiceOver checklist.

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the plugins/accessibility-compliance/skills/screen-reader-testing folder from the GitHub repo wshobson/agents into my ~/.claude/skills/screen-reader-testing/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/wshobson/agents.git /tmp/agents && mkdir -p ~/.claude/skills && cp -r /tmp/agents/plugins/accessibility-compliance/skills/screen-reader-testing ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal.
  2. Clone the repo: git clone https://github.com/wshobson/agents.git /tmp/agents
  3. Create the skills folder: mkdir -p ~/.claude/skills
  4. Copy the skill: cp -r /tmp/agents/plugins/accessibility-compliance/skills/screen-reader-testing ~/.claude/skills/
  5. Restart Claude Code and ask something like "test this page with a screen reader" to trigger it.
  6. For real validation, enable VoiceOver on macOS (Cmd+F5) or install NVDA from nvaccess.org on Windows.
