What is Accessibility Testing?

Accessibility testing is a process of making your web and mobile applications easily accessible to people with disabilities such as visual, hearing, mobility, and cognitive impairment

To achieve this, developers and testers thoroughly evaluate the product against established accessibility standards and laws such as WCAG Compliance to solve any accessibility issues.

The objective of accessibility testing is to create an inclusive digital environment by removing any accessibility barriers.

Examples of Accessibility Testing

A few primary examples include color contrast, text alternatives, ARIA (Accessible Rich Internet Applications) testing, and keyboard navigation:

  • Color Contrast: Testing the color contrast of text against its background to ensure it meets the WCAG (Web Content Accessibility Guidelines) standard, such as a minimum contrast ratio for normal text and large text.
  • Text Alternatives: Alt text or alternative text is for users who cannot see the images where testers verify images for appropriate alt attributes or aria-labels.
  • Accessible Rich Internet Applications (ARIA) Testing: Ensuring that ARIA roles and attributes are correctly applied to interactive elements like buttons, form controls, and live regions to enhance the screen reader experience.
  • Keyboard Accessibility: This implies navigating the website or app using only the keyboard  (e.g., the “Tab” key). It’s important to test keyboard shortcuts that can access, focus, and activate all interactive elements, such as links, buttons, and form controls.

Why should Companies focus on Accessibility Testing?

Did you know that an estimated 1.3 billion people worldwide experience significant disability?  

Ensuring accessibility is a matter of equal rights. It aligns with fairness and equal opportunities for people with disabilities to participate fully in society, including the digital world. There is an emphasis on accessibility testing for the following reasons: 

  • Legal Compliance
  • Inclusivity
  • Brand Awareness

Legal Compliance

To comply with legal requirements, websites and apps must be accessible to people with disabilities globally. 

  • In 2023, 77% of accessibility lawsuits are being filed against organizations with under $25 million in revenue. 
  • The fine for these regulations is about $75,000 – $150,000, a huge sum for growing companies, especially compared to the cost of making your website accessible.

Inclusivity

Commitment to inclusivity is a social responsibility that positively impacts the organization’s reputation.

  • By 2050, it is estimated that 16% of the world’s population will be over 65, increasing the need for accessible digital experiences.
  • By catering to individuals with disabilities, businesses can tap into a larger customer base and enhance user engagement. Accessible websites and apps attract a broader audience, fostering business growth and sustainability.
  • Apart from the business implications, it also holds a moral responsibility.

Understanding Digital Accessibility Testing Standards

The WCAG compliance provides a comprehensive framework for creating web content that is perceivable, operable, understandable, and robust for all users, including those with disabilities. 

  • WCAG stands for Web Content Accessibility Guidelines. 
  • It is a set of internationally recognized guidelines developed by the World Wide Web Consortium (W3C) to ensure digital content is accessible to people with disabilities.

4 WCAG Principles

The main goal of any accessibility compliance testing should be to determine if a web application is compatible with the 4 WCAG principles known as POUR: 

  1. Perceivable
  2. Operable
  3. Understandable
  4. Robust

Further, there are 3 conformance levels in WCAG

  1. Level A is the minimum conformance level to ensure web content is accessible for most users with disabilities.
  2. Level AA is a higher level of conformance than Level A and is designed to ensure web content is accessible to a broader range of users with disabilities, including those with severe disabilities.
  3. Level AAA is the highest level of conformance and is designed to ensure that web content is accessible to all users, regardless of disability.

Legal Acts Followed in Different Countries

Governments mandate companies to comply with accessibility guidelines as it is consistent with the principles of equal rights, legal obligations, social responsibility, and market considerations. The goal is to establish a more inclusive and equitable society worldwide, allowing everyone to participate fully.

Here are examples of web accessibility compliances in different regions:

RegionLaws / CompliancesOverview
USAAmericans with Disabilities Act (ADA) ADA Compliance requires public businesses and organizations to provide accessible digital content and services. ADA Testing includes websites, mobile apps, and other online platforms.

UKEquality Act 2010It covers disability discrimination and requires online service providers to make reasonable adjustments to ensure accessibility.
EUEuropean Union Web Accessibility DirectiveThe directive mandates that every website and app in the public sector must have an accessibility statement. It also requires the implementation of a feedback mechanism, which allows users to bring accessibility issues to the attention of website administrators or request access to inaccessible content. 
CanadaAccessibility for Ontarians with Disabilities Act (AODA)AODA Compliance is a provincial law in Ontario, Canada that aims to make the province accessible and prohibits discrimination on various grounds, including disability. As a result, government agencies and organizations providing services to the public must ensure their digital content is accessible.
AustraliaDisability Discrimination Act (DDA)The DDA requires that public and private sector organizations provide equal access to goods, services, and facilities, including digital content, to individuals with disabilities.
IndiaRights of Persons with Disabilities Act (RPwD Act)This mandates that the government, private organizations, and educational institutions make electronic and information technology accessible to people with disabilities.

Note: Companies can face legal risks and penalties of up to $150,000 by not adhering to accessibility standards, but following guidelines can mitigate these risks.

Use Cases for Digital Accessibility Testing

Common use cases across different industries and domains include compliance with prevailing standards to test and fix accessibility bugs that users with special requirements might face daily.

  • E-Learning:  Accessibility testing in this domain allows students with disabilities to have the same educational opportunities as their peers. This involves checking resources for closed video captions, alt text on images, and keyboard navigation through course content.
  • Medical and Healthcare: To ensure disabled individuals can access vital health information, book appointments, and access medical services. Accessibility testing of electronic health records, voice-activated technologies, and captioning services is critical..
  • Banking and Financial Services: This encompasses testing the bank’s website for screen reader compatibility to ensure that individuals with visual impairments can access their accounts and perform transactions. Financial institutions must ensure that their account registration, fund transfers, and bill payments are accessible to all.
  • Government and Public Sector: Governments provide essential services and information online. Ensuring accessibility of these official online platforms is critical. Official documents, reports, and publications should be created with accessibility in mind.
  • Public Transportation and Travel: Transportation services must prioritize accessibility features like screen reader compatibility, easy navigation, and alternative text for their mobile apps and websites. This allows people with disabilities to plan their travel and book easily.
  • E-commerce Portals: It is important to ensure that online shopping platforms are accessible to people with disabilities. This means they should be able to browse products, add to the cart, and easily complete transactions. Images of products should have descriptive alt text to help users with visual impairment. 

Who should perform Accessibility Testing?

To ensure digital experiences are inclusive and meet the needs of all users, it is important to have a combination of different teams involved in accessibility testing.
