Frequently Asked Questions
Digital accessibility testing tools help designers, members of dev teams, product owners, and others check web pages, mobile applications, and other digital content against accessibility standards– to learn they are accessible for everyone, including people with disabilities.
No. Automated accessibility testing tools enable testers to reduce the volume of manual tests they have to do without machine assistance. Using Intelligent Guided Tests (IGTs) and other semi-automated tools, testers can focus manual testing efforts on more complex issues that can’t yet be detected automatically.
The goal of accessibility testing for web applications is to make sure that websites deliver highly functional, bug-free, and accessible experiences across browsers and devices–for everyone–including people with disabilities. The goal of testing mobile native apps is to ensure that there are no accessibility issues within the native or hybrid mobile app across a wide range of Android and/or iOS devices, so that the applications are also accessible for everyone who uses them.
No, JAWS, NVDA, and VoiceOver are three very popular screen readers that are used by many people with low or no vision. While automated and semi-automated tests can eliminate a large percentage of issues that may affect screen readers, manual testing with screen readers is sometimes still required to be completely certain that all potential issues have been addressed.
Google Lighthouse has actually run on Deque’s open-source accessibility library, axe-core, since 2017. Deque owns and maintains the axe-core project and also uses it to power axe DevTools. However, Lighthouse does not run the full set of more than 70 tests that axe DevTools does.
Some vendors want you to believe that always flagging “more issues” is better. So much so, that many tools produce inaccurate results – or false positives. This is evident in comparative reviews with accessibility experts who participate in setting the WCAG standards. False positives lead to dev team testing abandonment and wasted time. Further, they undermine the credibility of accessibility team leaders who recommend these tools and practices.
