Best Tools for Website Accessibility Testing in 2024

Most websites have some accessibility barrier that makes it difficult for people with disabilities to use. Accessibility testing ensures that your website is accessible to all, including people with disabilities with vision, hearing, physical, speech, cognitive, language, learning, and neurological. On a broader front, website accessibility testing is part of the usability testing process.

What is Accessibility Testing?

The process of accessibility testing basically involves reviewing your application, website, or other forms of digital content using common standards. The fundamental goal is to make technology accessible to everyone, especially people with impairments such as hearing loss, color blindness, and other disadvantaged populations. Accessibility testing can be seen as a subset of Usability Testing.

Accessibility testing can be performed in two ways- Manual Testing and Automation Testing. This particular testing process can be conducted by two groups of individuals, namely, experts and users.

Expert testing covers inspecting the software application or website based on operability, assistive technologies, structural examination, and perception. User testing, on the other hand, is real people reviewing the software from the end-user perspective to identify faults.
