Accessibility

Accessibility testing is the process of ensuring that a web application is accessible to people with different disabilities. A web application mostly consists of components such as content, images, input fields, tables, switches, links, and buttons. Accessibility testing helps validate that all these web components can be accessed and used properly by users with visual, hearing, motor, or cognitive disabilities, including users who rely only on keyboard navigation or screen readers.
