Overview

Test for WCAG 2.2 AA compliance with axe-core + Playwright, keyboard navigation audits, screen reader testing, ARIA pattern validation, and legal compliance mapping (ADA, EAA, Section 508). Automated tools catch 30-40% of issues — this skill covers automated and manual testing together. Use when: "accessibility," "a11y," "WCAG," "screen reader," "axe," "keyboard navigation," "ARIA," "ADA compliance." Not for: cookie-consent/GDPR compliance — use compliance-testing; pixel-diff visual regression — use visual-testing. Related: playwright-automation, compliance-testing, visual-testing, ci-cd-integration.

Make an application usable by people who rely on keyboards and assistive technology, and prove it with tests that run in CI. A button that passes `toBeVisible()` can still be unreachable by keyboard; a page with zero axe violations can still be impossible to operate with a screen reader. Automated tools catch 30-40% of accessibility issues — this skill covers the automated scan plus the keyboard, screen reader, and ARIA-state testing that catch the other 60-70%.

Discovery Questions

Check .agents/qa-project-context.md first — if it exists, use it as the foundation and skip anything already answered.

Requirements and compliance (sets the target level and audit obligations)

What WCAG conformance level is required — A, AA, or AAA? AA is the practical legal default.
What laws apply — ADA, EAA/EN 301 549, Section 508, AODA? Each maps to a WCAG level.
Is there a VPAT or accessibility statement to maintain, or contractual a11y clauses from enterprise/government customers?

Current state (tells you whether you're auditing or preventing regressions)

Has an audit run before? What were the findings, and what's already in the backlog?
Does the design system carry accessibility guidance and accessible components?

Testing infrastructure (determines what you can automate vs. must do by hand)

Is automated a11y testing already in CI?
Which screen readers does the team test with — VoiceOver, NVDA, JAWS, TalkBack?

Core Principles

Automated testing catches 30-40% of issues — no more. axe-core finds missing alt text, low contrast, missing labels, and invalid ARIA. It cannot tell you whether alt text is meaningful, whether tab order is logical, or whether a custom widget is operable. Passing axe is necessary, not sufficient. Crucially, axe ships no automated rule for several WCAG 2.2 success criteria (2.4.11 focus-not-obscured, 2.5.7 dragging movements, and 2.5.8 target-size only partially) — a green axe run does not equal 2.2 AA conformance.
Semantic HTML first, ARIA as last resort. Native elements (<button>, <nav>, <input>, <dialog>) carry built-in semantics, keyboard behavior, and screen reader support. A <div role="button"> also needs tabindex, Enter/Space handlers, focus styles, and ARIA state — all of which a <button> gives you free. Reach for ARIA only when no native element fits.
Test in impact order: keyboard, screen reader, automated. Keyboard issues physically block users from features (highest impact). Screen reader issues confuse with wrong announcements. Automated checks catch the mechanical remainder. Start where the damage is worst, not where the tooling is easiest.
Accessibility is a quality attribute, not a feature. Test it continuously like performance or security — every new component, every PR. Retrofitting accessibility onto a finished product costs 10-100x more because inaccessible patterns get baked into the component library.
Test with real assistive technology. Browser DevTools and axe extensions are dev aids, not substitutes for VoiceOver (macOS/iOS), NVDA (Windows), and TalkBack (Android), which each behave differently. Reserve manual AT passes for complex custom widgets.

Automated Scanning with axe-core + Playwright

Install @axe-core/playwright (the 4.11.x line; it tracks axe-core's major.minor). Wrap it in a reusable checkAccessibility(page, testInfo, options) helper that filters to the WCAG tags ['wcag2a', 'wcag2aa', 'wcag22aa'], attaches the full results JSON to the test for the audit trail, and asserts violations.toHaveLength(0). Loop it over every key page and over interactive states (modal open, menu expanded), not just the default load.

Suppress a rule only with a documented justification (a tracking issue or inline comment) and exclude third-party widgets you don't own rather than disabling the rule globally.

See references/recipes.md for the install command, RGAA tag caveat, the full helper, the page-loop and interactive-state specs, rule suppression, and CI integration.

Manual Testing Checklist

Automated scanning is the floor. These checks need a human (or a keyboard-driven Playwright spec — see references/recipes.md for the keyboard specs).

Tab order is logical — left-to-right, top-to-bottom for LTR. No surprise focus jumps.
All interactive elements reachable via Tab / Shift+Tab.
Focus indicator visible on every focused element. No outline: none without a replacement.
Skip link works — first Tab reveals "Skip to main content"; Enter moves focus to <main>.
Enter activates buttons/links; Space activates buttons and toggles checkboxes.
Escape closes modals, dropdowns, tooltips; focus returns to the trigger.
Arrow keys navigate within tabs, menus, radio groups, tree views.
No keyboard traps (modal dialogs intentionally trap until dismissed — that's allowed).
Custom widgets operable without a mouse (sliders, date pickers, drag-and-drop).

Screen Reader	OS	Browser	Free?
VoiceOver	macOS/iOS	Safari	Yes (Cmd+F5)
NVDA	Windows	Firefox/Chrome	Yes
JAWS	Windows	Chrome/Edge	No
TalkBack	Android	Chrome	Yes

Page title announced on navigation.
Headings form a navigable outline (h1 → h2 → h3, no skipped levels).
Images have descriptive alt text (or alt="" for decorative).
Form inputs announce their labels when focused.
Required fields announced as required; errors associated with their input.
Live regions announce dynamic content (toasts, loading states).
Buttons/links announce their purpose (no "click here").

Color contrast and visual

Normal text: 4.5:1 minimum (WCAG AA). Large text (18pt+ / 14pt+ bold): 3:1.
UI components and graphical objects: 3:1 against adjacent colors.
Information never conveyed by color alone — add icons, patterns, or text.

Form and error accessibility

Every input has a visible <label> tied via for/id (placeholder is not a label).
Required fields indicated visually and programmatically (required / aria-required).
Errors use aria-describedby to link to the input and role="alert" to announce.
Focus moves to the first error on submission failure.
Related fields grouped with <fieldset> and <legend>.

WCAG 2.2 Quick Reference

Level A (must fix)

Criterion	What it means	Common failure
1.1.1 Non-text Content	Images have alt text	`<img>` without `alt`
1.3.1 Info and Relationships	Structure via HTML semantics	`<div>` styled as a heading
2.1.1 Keyboard	All functionality via keyboard	Custom widget responds only to mouse
2.4.1 Bypass Blocks	Skip navigation link	No skip link
3.1.1 Language of Page	`<html lang="en">` set	Missing `lang`
3.3.1 Error Identification	Errors described in text	Error shown only by red border
4.1.2 Name, Role, Value	Custom controls expose name/role	`<div onclick>` with no role

Level AA (most common legal requirement)

Criterion	What it means	Common failure
1.4.3 Contrast (Minimum)	4.5:1 normal, 3:1 large	Light gray on white
1.4.4 Resize Text	Scales to 200% without loss	Fixed-height containers clip text
1.4.11 Non-text Contrast	UI components 3:1	Low-contrast input borders
2.4.7 Focus Visible	Keyboard focus visible	`outline: none` with no replacement
2.5.8 Target Size	Touch targets 24×24px min	Tiny icon buttons
3.3.2 Labels or Instructions	Inputs have labels	Placeholder as the only label
3.3.8 Accessible Auth	No cognitive function test	CAPTCHA with no alternative

Level AAA (nice to have)

Criterion	What it means
1.4.6 Contrast (Enhanced)	7:1 normal text, 4.5:1 large
2.4.9 Link Purpose (Link Only)	Link text alone describes destination
3.1.5 Reading Level	Lower-secondary education level

Accessible Patterns

Test on the accessible tree (roles, names, ARIA state), not on CSS. The patterns you need runnable tests for:

Forms — error linked via aria-describedby, aria-invalid='true', focus on first error.
Modal/dialog — aria-modal='true', aria-labelledby, focus trapped, Escape returns focus.
Interactive states — opened dropdown (role="menu" or role="listbox", aria-expanded), loading skeleton (aria-busy='true' during fetch), toast (aria-live='polite'). These carry different ARIA per state, so click to trigger the state change and assert the open-state ARIA — the default page snapshot never exercises them.
Data tables — columnheader roles, aria-sort reflects the active sort.
Landmarks — exactly one main; banner, navigation, contentinfo present.

See references/patterns.md for the full runnable tests for every pattern above.

ARIA Snapshots

Playwright's toMatchAriaSnapshot() captures the accessible tree as YAML and asserts against it — the fastest way to catch a regression where a visual change silently breaks semantics (a <div> restyled to look like a button, a heading demoted to plain text). It checks structure and accessible names, not pixels, so it's complementary to visual-testing, not a replacement. Scope snapshots to a stable container; whole-page snapshots over async content go flaky. See references/patterns.md for navigation and form snapshot examples.

Legal Compliance Mapping

Law / Standard	Region	WCAG level required	Enforcement
ADA	USA	AA (court precedent)	Lawsuits (private right of action)
Section 508	USA (federal)	WCAG 2.0 AA	Federal procurement requirement
EAA	EU	EN 301 549 (WCAG 2.1 AA)	In force since 28 June 2025. Member states actively enforcing; private cause of action varies (DE, FR, IE most active). EN 301 549 expected to align with WCAG 2.2 next revision.
AODA	Ontario, Canada	WCAG 2.0 AA	Fines up to $100K/day
EN 301 549	EU	WCAG 2.1 AA	Public procurement requirement
Equality Act 2010	UK	WCAG 2.1 AA (guidance)	Lawsuits
ISO/IEC 40500:2025	International	Equivalent to WCAG 2.2 (Oct 2023)	Useful for procurement/RFP language; freely available from ISO

Practical target: if you serve US or EU users, WCAG 2.2 AA is the target for new development — the EAA is in force, EN 301 549 is expected to update to 2.2, and ISO/IEC 40500:2025 (published Sept 2025) codifies WCAG 2.2 internationally. WCAG 2.1 AA is the legacy minimum where 2.2 can't be reached immediately.

WCAG 3 status: W3C published an updated WCAG 3 working draft in March 2026 that renamed "Outcomes" to "Requirements" and moved away from binary pass/fail grading; it lists ~174 requirements. It remains a workin
