Question 1

What is accessibility testing?

Accepted Answer

Accessibility testing is the process of evaluating a website, web app, or mobile app to ensure people with disabilities can use it. It checks digital products against standards like WCAG, ADA, Section 508, and the EAA, covering users with visual, hearing, motor, cognitive, and speech disabilities. Testing combines automated scans, manual checks, and assistive-technology validation.

Question 2

What is accessibility testing in software testing?

Accepted Answer

In software testing, accessibility testing is a type of non-functional testing that verifies an application is usable by people with disabilities. It sits alongside functional, performance, and security testing in the QA cycle, and validates that UI elements work with screen readers, keyboards, and other assistive technologies before release.

Question 3

What are the types of accessibility testing?

Accepted Answer

There are three main types: automated testing, which uses tools to scan code against WCAG rules; manual testing, where testers check keyboard navigation, contrast, and structure by hand; and user testing, where people with disabilities use the product with real assistive technology. Automated tools catch roughly 30 to 50 percent of issues, so the three are used together.

Question 4

How do you do accessibility testing?

Accepted Answer

Accessibility testing follows four steps: run an automated scan to flag obvious WCAG violations, perform manual checks for keyboard navigation and logical structure, validate with screen readers like NVDA, VoiceOver, or TalkBack, and then triage and fix issues by user impact. Best practice is to test continuously rather than as a one-time audit.

Question 5

How do you do accessibility testing manually?

Accepted Answer

Manual accessibility testing means checking a product by hand for barriers automated tools miss. Navigate the entire interface using only a keyboard, verify focus order and visible focus states, check color contrast, confirm headings and labels are logical, and test with a screen reader to hear how content is announced. Manual testing is essential for context-dependent issues like reading order and meaningful link text.

Question 6

What is web accessibility testing?

Accepted Answer

Web accessibility testing specifically evaluates websites and web applications against WCAG to ensure they work for users with disabilities. It checks elements like alt text on images, color contrast, form labels, keyboard operability, and ARIA roles across browsers, distinct from mobile or document accessibility testing.

Question 7

Why is accessibility testing important?

Accepted Answer

Accessibility testing matters because over 1 billion people worldwide live with a disability, and inaccessible products exclude them. Beyond inclusion, it reduces legal risk as ADA and EAA lawsuits continue to rise, improves SEO and usability for all users, and is far cheaper to fix early than after release.

Question 8

What standards does accessibility testing check against?

Accepted Answer

Accessibility testing is measured against WCAG (Web Content Accessibility Guidelines), the international standard with levels A, AA, and AAA. It also maps to legal frameworks: the ADA in the US, Section 508 for federal sites, the European Accessibility Act (EAA) and EN 301 549 in the EU, and AODA in Ontario, Canada.

Question 9

What issues can accessibility testing find?

Accepted Answer

Accessibility testing detects barriers such as missing alt text on images, insufficient color contrast, unlabeled form fields, incorrect heading hierarchy, broken ARIA attributes, keyboard traps, and missing focus indicators. Automated tools find structural and code-level issues, while manual testing uncovers context problems like illogical reading order.

Question 10

Can accessibility testing be fully automated?

Accepted Answer

No, accessibility testing cannot be fully automated. Automated tools reliably catch about 30 to 50 percent of WCAG issues, mainly code-level ones like contrast and missing labels. Context-dependent criteria such as meaningful alt text, logical tab order, and screen-reader usability require human judgment, so automated scans should be paired with manual and assistive-technology testing.

Question 11

How often should you run accessibility tests?

Accepted Answer

Accessibility testing should be continuous, not a one-time check. Run automated scans on every build in your CI/CD pipeline, schedule recurring WCAG scans daily or weekly to catch regressions from content changes, and do manual screen-reader and keyboard testing before major releases.

Question 12

How do you automate accessibility testing?

Accepted Answer

You automate accessibility testing by integrating WCAG checks into your existing test suite. TestMu AI lets you add accessibility assertions inside Selenium, Cypress, and Playwright tests, monitor the DOM live for violations, schedule recurring scans across whole sites, and surface fixes inside your IDE via its MCP Server, so coverage scales with every build.
