Production guide for automated, semi-automated, and manual web accessibility (a11y) testing. Covers WCAG 2.2 Level AA/AAA compliance validation using @axe-core/playwright, Pa11y, Google Lighthouse CI, screen reader verification (NVDA, VoiceOver), keyboard navigation audits, focus management, and color contrast compliance.

Trigger Conditions

Running automated accessibility test suites in CI/CD pipelines.
Auditing web apps for WCAG 2.1 / 2.2 Level AA compliance and legal accessibility requirements (ADA, EAA).
Debugging keyboard traps, missing ARIA labels, or broken screen reader navigation.
Writing test cases for focus trapping in modals and custom dialogs.

Core Testing Workflows

import { test, expect } from '@playwright/test';
import AxeBuilder from '@axe-core/playwright';

test.describe('Accessibility Automated Audits', () => {
  test('homepage should have zero critical or serious a11y violations', async ({ page }) => {
    await page.goto('/');

    const accessibilityScanResults = await new AxeBuilder({ page })
      .withTags(['wcag2a', 'wcag2aa', 'wcag22aa'])
      .disableRules(['color-contrast']) // If tested separately
      .analyze();

    expect(accessibilityScanResults.violations).toEqual([]);
  });

  test('modal dialog should trap focus and pass a11y audit', async ({ page }) => {
    await page.goto('/dashboard');
    await page.click('button#open-modal');

    // Verify modal is open and focused
    const modal = page.locator('[role="dialog"]');
    await expect(modal).toBeVisible();

    const modalAudit = await new AxeBuilder({ page })
      .include('[role="dialog"]')
      .analyze();

    expect(modalAudit.violations).toEqual([]);

    // Verify keyboard escape closes modal
    await page.keyboard.press('Escape');
    await expect(modal).toBeHidden();
  });
});

2. Automated Pa11y CI Configuration (`.pa11yci.json`)

{
  "defaults": {
    "standard": "WCAG2AA",
    "timeout": 15000,
    "runners": ["axe", "htmlcs"],
    "ignore": [
      "WCAG2AA.Principle1.Guideline1_4.1_4_3.G18.Abs"
    ]
  },
  "urls": [
    "http://localhost:3000/",
    "http://localhost:3000/login",
    "http://localhost:3000/pricing",
    "http://localhost:3000/docs"
  ]
}

Tab Navigation: All interactive elements (<button>, <a>, <input>) can receive focus in logical reading order.
Focus Indicators: Visible, high-contrast focus rings (outline: 2px solid var(--focus-color) with outline-offset).
No Keyboard Traps: Focus can enter and leave components using only Tab, Shift+Tab, and Esc.
Landmarks: Proper semantic tags (<header>, <nav>, <main>, <footer>, <aside>).
ARIA Attributes: aria-expanded, aria-controls, aria-haspopup, and aria-live updated dynamically.

4. Material Design 3 (M3) Accessibility & State Layer Assertions (https://m3.material.io/foundations/accessible-design/overview)

M3 enforces rigorous interaction states via standardized State Layer Opacities and an expanded 48×48dp Target Size:

1. M3 State Layer Opacity Matrix:

Hover: 8% (0.08) overlay of on-surface or primary.
Focus: 10% (0.10) overlay with high-contrast ring.
Pressed: 10% (0.10) overlay.
Dragged: 16% (0.16) overlay.
Disabled: Container opacity 38% (0.38), content opacity 38% (0.38).

2. 48×48dp Minimum Touch Target Assertion (Playwright):

import { test, expect } from '@playwright/test';

test('interactive controls satisfy M3 48x48dp touch target standard', async ({ page }) => {
  await page.goto('/');

  const buttons = page.locator('button, a[role="button"], input[type="checkbox"]');
  const count = await buttons.count();

  for (let i = 0; i < count; i++) {
    const btn = buttons.nth(i);
    const box = await btn.boundingBox();
    if (box && await btn.isVisible()) {
      // M3 requires min 48x48dp bounding box for touch targets
      expect(box.width).toBeGreaterThanOrEqual(48);
      expect(box.height).toBeGreaterThanOrEqual(48);
    }
  }
});

Zero-tolerance accessibility criteria for all generated interfaces:

No Stripped Focus Outlines: Zero tolerance for outline: none or focus:outline-none without an explicit, high-contrast replacement ring (focus-visible:ring-2 focus-visible:ring-offset-2).
Semantic Elements Only: Ban on non-semantic clickable divs/spans (<div onClick=...>). Every click target must be an authentic <button>, <a>, or provide role="button" + tabIndex={0} + keyboard event handlers (onKeyDown for Enter & Space).
Touch Target Minimums: All interactive controls must satisfy WCAG 2.2 SC 2.5.8 (minimum 24×24px, recommended 44×44px with adequate padding).
Text Contrast Non-Negotiable: Minimum 4.5:1 for normal body text, 3:1 for large text (18pt / 14pt bold).
Meaningful Labels: Zero icon buttons without aria-label or screen-reader-only text (<span className="sr-only">).

Bahasa Indonesia

Integrasi Orkestrasi

global-a11y-i18n-expert: Pedoman standar WCAG, pola ARIA, dan aksesibilitas internasional.
e2e-testing-expert: Integrasi pengujian aksesibilitas otomatis ke pipeline Playwright CI.
design-system-architect, senior-frontend: Validasi aksesibilitas komponen headless dan desain UI.
anti-slop: Menegakkan aturan aksesibilitas tanpa kompromi (mencegah penghapusan outline fokus, div-soup tombol, dan pelanggaran kontras warna).

Deskripsi

Panduan produksi untuk pengujian aksesibilitas web (a11y) otomatis dan manual. Memastikan kepatuhan terhadap standar WCAG 2.2 Level AA/AAA menggunakan @axe-core/playwright, Pa11y, Lighthouse CI, pengujian screen reader, navigasi keyboard, dan kontras warna.

Kondisi Pemicu

Menjalankan audit aksesibilitas otomatis di pipeline CI/CD.
Memverifikasi kepatuhan hukum aksesibilitas (WCAG 2.2, ADA, EAA).
Menguji alur keyboard dan pembaca layar (screen reader) pada komponen kompleks seperti modal dan dropdown.

Kepatuhan Aksesibilitas & State Layer Material Design 3 (M3) (https://m3.material.io/foundations/accessible-design/overview)

M3 menetapkan standar interaksi yang konsisten melalui Matriks Opacity State Layer dan Target Sentuh Minimum 48×48dp:

Matriks State Layer:
- Hover: Opacity 8% (0.08)
- Focus: Opacity 10% (0.10)
- Pressed: Opacity 10% (0.10)
- Dragged: Opacity 16% (0.16)
- Disabled: Opacity container dan konten 38% (0.38)
Target Sentuh 48×48dp: Meskipun aset visual (misal checkbox atau ikon) hanya berukuran 24×24px, area sentuh interaktif wajib diperluas menjadi minimal 48×48dp menggunakan padding atau pseudo-elemen ::after.

Gerbang Verifikasi Aksesibilitas Anti-Slop

Kriteria aksesibilitas tanpa toleransi untuk seluruh antarmuka yang dihasilkan:

Dilarang Menghapus Outline Fokus: Standar nol toleransi untuk outline: none atau focus:outline-none tanpa pengganti ring berlatar kontras tinggi (focus-visible:ring-2 focus-visible:ring-offset-2).
Wajib Elemen Semantik: Larangan keras membuat div/span non-semantik yang dapat diklik (<div onClick=...>). Setiap target klik harus merupakan <button>, <a>, atau menyediakan role="button" + tabIndex={0} + penangan keyboard (onKeyDown untuk tombol Enter & Space).
Target Sentuh Minimum: Semua kontrol interaktif harus memenuhi standar WCAG 2.2 SC 2.5.8 (minimal 24×24px, direkomendasikan 44×44px dengan padding memadai).
Kontras Teks Non-Negosiabel: Minimal rasio 4.5:1 untuk teks biasa, dan 3:1 untuk teks berukuran besar (18pt / 14pt bold).
Label Bermakna: Dilarang membuat tombol ikon tanpa aria-label atau teks khusus pembaca layar (<span className="sr-only">).
