Techopedia explains Accessibility Testing
Accessibility testing is part of the system testing process and is somewhat similar to usability testing. In an accessibility testing process, the tester uses the system or component as it would be used by individuals with disabilities. The disabilities in such individuals can range from visual impairment, hearing impairment, learning disabilities and/or people with missing or non-functional limbs.
Typically, accessibility testing is done on logical IT components such as software, applications and websites. However, some hardware components are also tested for accessibility.
