Why accessibility testing is important?

The Internet and web usage is growing rapidly as per user demand. In every industry, technology is being used; be it educational, medical, financial, manufacturing, IoT, security, eCommerce and others. Web accessibility becomes a mandatory practice to give each and everyone equal access and equal opportunity to explore web. 

Accessibility testing makes sure the application is accessible to people with or without disabilities. These disabilities would include visual impairments, auditory disorder, hyperacusis, reading disorder, intellectual disability, and other disorders. 

According to the World Health Organization (WHO), 15% of the population has a disability. These specially-abled people have the right to use and interact with the web.

Web accessibility guidelines (WCAG) are published by W3C. They are a set of recommendations for making Web content more accessible for people with disabilities.

Government agencies all over the world have come up with legislation, which enforces IT products to be accessible by specially-abled people. E.g. Section 508 compliance in the USA.

There are few tools that can help you test against particular issues related to accessibility standards.
