What is automated accessibility testing?

Automated accessibility testing runs rule-based WCAG checks inside your test code or CI pipeline, so every build is scanned for issues such as missing alt text, low color contrast, and unlabeled form fields. TestMu AI runs these checks with axe-core inside Selenium, Playwright, Cypress, and Appium tests.

How do I automate accessibility testing?

Set your LT_USERNAME and LT_ACCESS_KEY, add the accessibility capability to your test configuration, then call the lambda-accessibility-scan hook after key pages load or turn on autoscan. Run the suite with the command you already use, and open the Accessibility tab of the build to see results. The Selenium accessibility guide walks through each step.

Which frameworks support accessibility automation?

Selenium on Chrome and Edge 90 and newer, Playwright on real Chrome, Cypress v10 and v9, and Appium on real Android and iOS devices. Java, C#, and Python suites built on TestNG, JUnit 5, NUnit, Robot Framework, or Cucumber work through their Selenium setup.

Can I run accessibility tests with Playwright?

Yes, on a real Chrome browser. Set the accessibility capabilities in playwright.config.js and call page.evaluate("lambda-accessibility-scan") after each stable page. Playwright's bundled pw-chromium is not supported because the accessibility extension does not load in it. See the Playwright accessibility docs.

How does accessibility testing work with Cypress?

Import lambdatest-cypress-cli/accessibility/scanner in cypress/support/e2e.js, set the accessibility options in lambdatest-config.json, and run lambdatest-cypress-cli run. Cypress v10 is current and v9 is supported as legacy. The Cypress accessibility docs cover both.

How do I add accessibility tests to my CI/CD pipeline?

Store LT_USERNAME and LT_ACCESS_KEY as CI secrets and run your usual test command, such as mvn test or npm test, in GitHub Actions, Jenkins, GitLab CI, CircleCI, or Azure DevOps. Start at WCAG Level A so legacy issues do not block every build, then move to AA as you fix them. The CI/CD integration guide has pipeline examples.

Which WCAG version should automated accessibility tests check?

Most teams target WCAG 2.1 Level AA, which is also the level the US Department of Justice ADA Title II rule names for state and local government websites. Set it with the accessibility.wcagVersion capability, for example wcag21aa.

What is the difference between scan hooks and autoscan?

A scan hook runs only where you call lambda-accessibility-scan, which keeps runs fast and focused on the pages that matter. Autoscan, set with accessibility.autoscan, checks every page navigation in the session without extra code.

Can automated accessibility testing replace manual testing?

No. Automated rules catch structural issues such as missing alt text, low contrast, and invalid ARIA on every run. Whether alt text is meaningful, whether tab order makes sense, and whether screen reader announcements are clear still need a person, which is where Accessibility DevTools and its Keyboard Scan come in.

Can AI coding agents set up accessibility automation?

Yes. The accessibility Agent Skill teaches Claude Code, Cursor, GitHub Copilot, Gemini CLI, and Codex CLI to add the capabilities and scan hooks from a prompt such as "scan the checkout page against WCAG 2.1 AA". The MCP Server brings the resulting reports back into your IDE.

How is accessibility automation different from accessibility scheduling?

Automation runs inside your tests, so it checks the pages your tests visit on every build. Scheduling needs no code and re-scans a URL list on a timetable. Most teams gate pull requests with automation and use accessibility scheduling to watch the live site.

Does accessibility automation work for mobile apps?

Yes. Add the accessibility capability to your Appium session and call lambda-accessibility-scan after each stable screen. Scans run on real Android and iOS devices, and results appear in the same dashboard. See app accessibility testing for the no-code options.
