Accessibility testing overview

Run automated accessibility checks on every test with WCAG 2.1 AA violation detection.

Accessibility testing is integrated directly into Check Studio test runs. Every page visited by your tests is scanned for WCAG 2.1 AA violations automatically.

How it works

  1. 1Tests run normally using Playwright
  2. 2After each page navigation, axe-core scans the DOM
  3. 3Violations are collected and reported alongside functional test results
  4. 4Severity is graded: critical, serious, moderate, minor

Enabling

// checkstudio.config.js
module.exports = {
  accessibility: {
    enabled: true,
    standard: 'WCAG2.1AA',
    failOn: ['critical', 'serious'],
  },
};
javascript

CI impact

Accessibility checks add ~200ms per page. For large suites, enable sampling to check 1 in 5 pages instead of every page.
