Role of Automated Tools in Acceptance Testing
The above said automated accessibility testing tools are very good at identifying pages and lines of code that need to be manually checked for accessibility.
check the syntax of the site's code
Search for known patterns that humans have listed
identify pages containing elements that may cause problems
identify some actual accessibility problems
identify some potential problems
The interpretation of the results from the automated accessibility testing tools requires experience in accessibility techniques with an understanding of technical and usability issues.
