Accessibility Testing

SoftwareTestingHelp.com defines that testing a web application in order to make sure that each and every user can easily access the website is known as Accessibility Testing.

The specialized and dedicated branch of testing that helps ensure that websites are indeed effective in this area is called “Web Accessibility Testing”.

Key standards include the WCAG – Web Content Accessibility Guidelines, which cover a wide range of recommendations for making Web content more accessible to a wider range of people with disabilities, including accommodations for blindness and low vision, deafness and hearing loss, limited movement, speech disabilities, photosensitivity, and combinations of these.

It is particularly important to industries such as the public sector. As the UK Government describes, accessibility should be integral to digital service development from the start, not an afterthought. Government sites not complying with requirements could be breaking the law.

The DWP Accessibility Manual lists a number of UK laws that require accessibility measures to be met, and the UK.gov team are running this promotional campaign to encourage compliance projects. This highlights the headline legislation: The Public Sector Bodies (Websites and Mobile Applications) (No. 2) Accessibility Regulations 2018.

Their guide provides a comprehensive review of both, covering software testing such as the role of automated testing, where they highlight it is not the be-all and end-all, it is essential to also incorporate manual testing to catch what automated tests do not, and also covering Accessibility, with specialisms such as Assistive Testing.

It also references their own detailed guide to Understanding Accessibility Requirements. This is a comprehensive guide, covering topics like Screen Reader Testing, Designing Screens and How To Do Accessibility Testing.

In his DevOps.com blog, Brad Henry describes five ways to embed accessibility into your development pipeline, so that the practices described here can be formalized into your team operations in such a way it becomes a default capability.

Vendor tools include the Microsoft Accessibility suite including Insights, a browser extension that helps developers find and fix accessibility issues in web apps and sites. SoftwareTestingHelp.com offers a list of 20 accessibility testing tools.

Leonardo Faria writes a very detailed walkthrough of using the Axe tool for testing accessibility compliance of websites and their components, and in this video, Jon Oliver explores combining it with Cypress, a popular testing tool, for automated testing of accessibility.

In their How It Works section Cypress explain their unique software architecture and suite of testing services that make it the ideal tool for web UI testing.
