What are accessibility testing tools?

Accessibility testing tools include tools used to ensure a website, software, mobile application or similar platform can meet the needs of users with disabilities. These tools identify issues that may affect their experience, helping project managers and other professionals determine how to resolve the concerns to create a seamless experience. They help verify the system complies with the Web Content Accessibility Guidelines (WCAG) established by the Web Accessibility Initiative (WAI) and World Wide Web Consortium (W3C). WCAG outlines the requirements for systems to support users with disabilities, such as:

  • Avoiding pop-ups

  • Including descriptive link text

  • Providing easy navigation

  • Using CSS layouts rather than HTML layouts

  • Writing with small, simple sentences and language
