Question 1

What is an accessibility testing platform?

Accepted Answer

An accessibility testing platform brings automated scans, manual and assistive-technology testing, scheduling, and reporting into one place, so a team can test websites and apps against WCAG and track fixes over time. A standalone checker scans one page; a platform covers the whole program.

Question 2

What does the TestMu AI accessibility testing platform include?

Accepted Answer

A Chrome extension for on-demand scans (Accessibility DevTools), WCAG checks inside Selenium, Playwright, Cypress, and Appium tests (automated accessibility testing), recurring site scans (accessibility scheduling), a native app scanner on real devices (mobile accessibility testing), screen reader testing, and an MCP Server for AI coding tools. Compare each one on the accessibility testing tools page.

Question 3

Can an AI coding agent set up accessibility testing?

Accepted Answer

Yes. The Accessibility Agent Skill lets Claude Code, Cursor, Copilot, and other coding agents wire WCAG scans into a Selenium, Playwright, or Cypress suite from one prompt. The Accessibility MCP Server adds three tools inside the IDE: scan a public URL, scan a local React app, or scan an app connected through a tunnel. Results land on the same accessibility dashboard.

Question 4

What is accessibility testing?

Accepted Answer

Accessibility testing checks whether people with disabilities can use a website or app, including people who rely on screen readers, keyboards, or magnification. It measures the product against WCAG and the laws built on it. For a full walkthrough, read the accessibility testing guide.

Question 5

Which standards can I test against?

Accepted Answer

WCAG 2.0, 2.1, and 2.2 at Levels A, AA, and AAA, which also underpin the ADA, Section 508, the European Accessibility Act and EN 301 549, and AODA. Each tool lets you choose the WCAG version and level a scan runs against.

Question 6

Will passing scans make my website ADA compliant?

Accepted Answer

Passing scans is strong evidence of WCAG conformance, but no tool can guarantee ADA compliance, which courts decide case by case. What the platform gives you is a documented program: dated scan history, severity-ranked issues, and exported reports that show continuous testing and remediation.

Question 7

Does TestMu AI provide a VPAT or ACR?

Accepted Answer

No. A VPAT or Accessibility Conformance Report describes your own product, so your organization writes it. The platform supplies the evidence behind it: scan results mapped to WCAG success criteria, remediation history, and PDF or CSV exports.

Question 8

How do I start a digital accessibility testing program?

Accepted Answer

Scan your 50 to 100 highest-traffic pages at WCAG 2.1 AA to get a baseline, then fix Critical issues that appear across many pages first, since they usually come from a shared template. Add checks to your CI pipeline so new code is tested, schedule a weekly scan of the live site, and run screen reader passes on your key user journeys.

Question 9

Can automated accessibility testing find every issue?

Accepted Answer

No. Automated rules catch structural issues such as missing alt text, low contrast, and unlabeled fields. Whether alt text is meaningful, whether focus order makes sense, and whether screen reader announcements are clear still need a person, which is why the platform pairs automated scans with keyboard scans and NVDA, JAWS, VoiceOver, and TalkBack testing.

Question 10

Does the platform test native mobile apps?

Accepted Answer

Yes. The native app scanner checks Android and iOS screens on real devices without code, Appium tests can add scan checkpoints, and KaneAI can insert scan steps into mobile tests. See mobile accessibility testing for the rules covered on each platform.

Question 11

How are accessibility issues prioritized?

Accepted Answer

Every issue is ranked Critical, Serious, Moderate, or Minor and linked to the WCAG success criterion it fails, with the failing element and fix guidance. You can group issues by type, criterion, or severity, hide accepted items, and track an Accessibility Web Score across releases.

Question 12

Can I test pages behind a login or on staging?

Accepted Answer

Yes. The Chrome extension scans any page you can open in your browser, scheduled scans can sign in with saved credentials or reach private environments through a tunnel, and automated tests reach whatever pages your test suite visits.

Question 13

How is TestMu AI different from a standalone accessibility checker?

Accepted Answer

Accessibility testing runs on the same cloud your team uses for functional testing, so scans ride along with existing Selenium, Playwright, Cypress, and Appium runs on real browsers and 10,000+ real devices. Web, native mobile, manual, and automated results all land in one dashboard instead of separate tools.
