Overview

Accessibility testing ensures web applications are usable by people with disabilities, including those using screen readers, keyboard navigation, or other assistive technologies. It validates compliance with WCAG (Web Content Accessibility Guidelines) and identifies barriers to accessibility.

When to Use

• Validating WCAG 2.1/2.2 compliance
• Testing keyboard navigation
• Verifying screen reader compatibility
• Testing color contrast ratios
• Validating ARIA attributes
• Testing form accessibility
• Ensuring focus management
• Testing with assistive technologies

Quick Start

Minimal working example:

// tests/accessibility/homepage.a11y.test.ts
import { test, expect } from "@playwright/test";
import AxeBuilder from "@axe-core/playwright";

test.describe("Homepage Accessibility", () => {
  test("should not have any automatically detectable WCAG A or AA violations", async ({
    page,
  }) => {
    await page.goto("/");
