Accessibility Testing is the process of evaluating a website or application to ensure it can be used by people with disabilities. This includes checking for compatibility with assistive technologies like screen readers, as well as ensuring that content is perceivable, operable, and understandable for all users. The goal of Accessibility Testing is to identify and fix barriers that may prevent individuals with disabilities from accessing information or services. By following guidelines such as the Web Content Accessibility Guidelines (WCAG), developers can create more inclusive digital experiences that cater to a wider audience.
