Axe Accessibility Testing

You are aware that Accessibility Testing is the practice of making the web and mobile apps usable to as many people as possible. It makes apps accessible to those with disabilities, such as vision impairment, hearing disabilities, and other physical or cognitive conditions. You have to perform the Accessibility Testing to meet the needs of all the users. As per the law – the Web Content Accessibility Guidelines (WCAG), Section 508, and the Americans with Disabilities Act (ADA), you have plenty of regulations to meet. One needs to ensure that the applications work with screen readers, speech recognition software, screen magnification, and more.

This article delves deeper into the concept of Accessibility Testing and discusses what needs to be tested as part of accessibility, importance of Accessibility Testing, and how you can achieve Accessibility Testing using Axe for web applications.
