The Potential and Importance of Accessibility Testing.

Posted By :Nuzhat Siddique |31st March 2023

Meeting and coping with customer expectations, shifting patterns, technology use, and growing the user base for digital applications present significant challenges in the expanding digital landscape. Because they do not take into account all end-user requirements during the design and development process, many applications today fall short of their full potential.


To build new technology that is usable by everyone, extraordinary effort is needed. For illustration, consider introducing an online application to the market that should be usable by everyone, including people who are blind, deaf, or have other physical or mental disabilities. Applications and testing for accessibility play a crucial part in this situation.


Accessibility testing: what is it?


It is a method for validating and confirming digital content that is accessible to all users, including those with disabilities like visual impairments, hearing loss, and other cognitive conditions, and that takes the form of applications (web, mobile, desktop, etc.).


This testing guarantees that the complete application is accessible to both people with and without disabilities and makes use of the features without the use of a mouse, keyboard, etc.


Guidelines for Accessibility Testing:


By following WCAG (Web Content Accessibility Guidelines), ADA, Section 508, and VPAT (Voluntary Product Accessibility Template) guidelines and standards, organizations can create web and other digital apps.


World Wide Web Consortium (W3C) sets the following guidelines for Accessibility testing:

PerceivableFor the end user to understand an interface and content, they must be presentable—for instance, alt text in images.
OperableThe user interface must have operable and easy navigation. Using the keyboard as an illustration
UnderstandableInstead of using color-coded instructions, the user interface's text must be readable as a meaningful statement.
RobustWhen a user views a URL on various viewports, such as desktops, mobile devices, and tablets, the user interface's content must be robust to be accessible by all users.


Why is testing for inclusivity so crucial?


The following factors highlight why accessibility testing is so important in the modern age.

  • Since 15% of the world's population has a disability, making digital tools and goods accessible can help a business gain market share.
  • Enhances the application's general SEO performance through improved usability and a clean UI.
  • A good public relations strategy guarantees the product and services are inclusive and is a great method to demonstrate a firm commitment to CSR. eventually increases customer loyalty and confidence, enhancing the reputation of your business.
  • The usable program aids businesses in avoiding legal issues



Additionally, with the quick spread of digital applications, it's critical to guarantee usability for all users. This access should adhere to IT accessibility laws and policies as well as various public, governmental, private, and nonprofit efforts that have been undertaken to support accessible technology.


Making electronic and information technology (EIT) accessible to persons with disabilities is the goal of Section 508 of the Rehabilitation Act of 1973. When a government agency develops, acquires, maintains, or utilizes EIT, it is subject to this regulation.


Some of the other related laws are:

  • Section 255 of the Communications Act
  • Americans with Disabilities Act (ADA)
  • Assistive Technology Act of 1998
  • Help America Vote Act of 2002
  • The 21st Century Communications and Video Accessibility Act of 2010


Accessibility Testing and Services


Focus Areas- Requirements and Consideration


Analysis and development of accessibility software must take into account users with a variety of disabilities, including

  • Visual: Low vision, colorblindness, full and partial blindness, and
  • Physical: Keyboard and cursor usage issue
  • Autism or any brain injury, cognitive
  • Hearing: Auditory issues such as hearing loss, blindness, hyperacusis, etc.
  • cerebral palsy, immobility, deafness, etc.

For users with the aforementioned disabilities to comprehend all of the information on the application or website, special software enablements are required. Applications' user interfaces are expected to (web, offline, desktop) adhere to specific standards that should alleviate the problems experienced by people with disabilities.


  • Applications that assist people with physical or motor disabilities by using a larger trackball mouse, a special keyboard, etc.
  • For people who are blind or visually impaired, there should be a keyword attribute that makes all images with pertinent information searchable.
  • Closed captioning, sign language interpreters, and other services that assist in turning audio into visual form


Accessibility Challenges


  • Organizations should carry out a thorough evaluation to guarantee that all accessibility requirements are covered during testing.
  • To verify accessibility test conditions and finish conformance testing, automation testing is insufficient. The need for manual testing with sufficient time, expense, resources, and expertise to cover the entire testing scope ultimately results from this gap.
  • Dynamic content and frequently shifting publishing patterns are frequently found on larger and more complex websites. As a result, it is challenging to validate every combination using the page-level test.
  • Information update from a third party: Many different organizations/sources have direct access to the material of large websites. It is crucial to determine whether the update of third-party data complies with the accessibility standard, which usually necessitates manual interoperability tests.
  • It can be difficult to consider accessibility requirements holistically while still adhering to legal and safety requirements.
  • To prevent rework, find the differences, problems, and flaws in the early stages of development. Every test run must involve extensive testing.


Accessibility Testing- Assistive Tools


Accessibility evaluations should be conducted by organizations at every stage. It does not, however, presently live up to expectations. The testing team expects the following fundamental usability features to meet the minimal accessibility standards while evaluating the application.


Descriptive Link Text

  • Avoid Pop-ups
  • Simple sentences and language
  • Easy navigations
  • Use of CSS layouts instead of HTML


The specifics of the technologies and instruments for accessibility testing are provided below. These resources make it easier for businesses to evaluate their desktop, web, and mobile applications.


Auditing Tools


On the market, there are a lot of instruments. When enabled or installed, they fully review the applications, analyze them, and then provide a list of accessibility issues for each page or application component.


  • Tools for auditing applications take the application URL and provide pertinent annotations highlighting accessibility issues.
  • Examines the code of the relevant apps and reports any accessibility issues based on the WCAG and other relevant standards and guidelines.
  • These tools return the recommended fixes after addressing the accessibility flaws and errors.


Automation Tools


The automation tool checks the web pages and provides information on accessibility errors while running on top of applications. It additionally offers computer add-ons. Installing and integrating these tools with task managers and automation frameworks like Selenium and Cucumber is possible.


Assistive Technology


One of the most versatile assistive technologies, screen readers make it easier for people to use websites and other apps.


Consider these helpful features:

  • An alternative caption for the picture that describes it
  • Form sections have distinct labels.
  • Use of straightforward and suitable designs, such as tables for table data, as opposed to the arrangement.
