What is WCAG Testing?

Definition, how WCAG testing has to be done to check if WCAG compliance is successfully met. Very brief section

Accessibility testing ensures that everyone can access and use digital products, regardless of their abilities. This includes individuals with:

  • Visual impairments: Color blindness, low vision, or complete blindness.
  • Hearing impairments: Difficulty hearing or complete deafness.
  • Physical or cognitive limitations: Difficulty using a mouse, keyboard, or touchscreen, or limitations in processing information.

WCAG Testing

To ensure inclusivity, developers follow the Web Content Accessibility Guidelines (WCAG). These international standards, developed through the W3C process, provide a roadmap for creating accessible web and mobile applications usable by everyone.

Why is WCAG Compliance Testing important?

Did you know: 90% of websites are inaccessible to people with disabilities relying on assistive technology

An Accessibility audit of Fortune 100 corporate websites identified 815,600 WCAG 2.1 accessibility issues out of which, the majority were Level A issues. This shows that Fortune 100 companies are failing to meet basic criteria for accessibility compliance.

WCAG Testing is thus required to ensure that the accessibility criteria is duly met.

Web Accessibility helps businesses with,

  • Larger Target Audience
  • Avoiding Legal Ramifications
  • Establishing Brand Recognition
  • Better User Experience

Larger Target Audience

Did you know an estimated 1.3 billion people – or 1 in 6 people worldwide – experience significant disability as per WHO.

WCAG helps target a larger audience who otherwise would not be able to consume the web content due to one or the other disability. Gartner suggests, that by 2023, digital products that fully conform to WCAG 2.0 compliance are expected to outperform their market competitors by 50%.

Business opportunity in WCAG compliance is significant as the Digital Accessibility TAM (Total Addressable Market) was valued at USD 484.70 Million in 2020. It is projected to reach USD 769.50 Million by 2028, growing at a CAGR of 5.99% from 2021 to 2028, Web Accessibility should not be missed.

Avoiding Legal Ramifications

There’s an increased sense of awareness towards web accessibility with assistive tools in the market more than ever. The number of Web Accessibility Lawsuits has risen exponentially, so much so that it has doubled in 2023 since 2018. 

Establishing Brand Recognition

Accessibility efforts signal to users that your brand is trustworthy and values the needs of all its users. Consumers are increasingly valuing businesses that prioritize accessibility and inclusivity. Performing WCAG Testing can enhance your brand’s image, fostering a positive perception among customers and the general public.

Demonstrating a commitment to WCAG compliance reflects an inclusive approach, ensuring that individuals with disabilities can access and engage with your digital content. This inclusivity contributes to a positive brand image and showcases a commitment to diversity.

Better User Experience

Accessibility improvements made during WCAG Testing often enhance the user experience for all users, not just those with disabilities. Optimizing digital content for accessibility can improve usability, navigation, and overall satisfaction for a broader range of users.

Comprehensive WCAG Accessibility Testing is a good way to avoid Lawsuits, ensure better user experience, enhance brand recognition and improve business growth with a larger target audience.

Who needs to perform WCAG Testing? 

Though WCAG testing is critical in all aspects of your software development process, the main stakeholders who are primarily responsible for ensuring adherence and testing are:

  • Developers: Responsible for building a website that considers easy access to all, fixing accessibility issues, and debugging for any failing accessibility standards and criteria.
  • QAs: Responsible for testing whether all the accessibility guidelines and criteria are successfully met by thoroughly testing the application against the success criteria prescribed by WCAG.
  • UX Designers: Responsible for creating an all-inclusive interface design that is accessible and usable by as many people as possible, regardless of their age, ability, or status. 
  • Product Managers: Responsible for evaluating accessibility pre-requisites, verifying accessibility with ease, and accessing WCAG-mapped issues to create VPAT reports and monitor them.

What are WCAG Accessibility Testing guidelines?

WCAG outlines four key principles to ensure everyone can access and understand web content:

Principles of WCAG Accessibility

  1. Perceivable: Information should be readily available to users with different sensory abilities. This includes providing alternatives for visual or auditory content, like text descriptions for images or captions for videos.
  2. Operable: Users with physical limitations should be able to interact with the content effectively. This means supporting navigation with keyboards or using alternative input methods like touchscreens.
  3. Understandable: Content should be clear, concise, and easy to comprehend. Avoid complex language, unfamiliar jargon, and solely relying on visuals for conveying information.
  4. Robust: Content needs to be compatible with various assistive technologies used by people with disabilities. This ensures the information can be interpreted correctly by screen readers, speech recognition software, and other assistive tools.

What are WCAG conformance levels?

Choosing the right WCAG conformance level depends on your specific context, target audience, and legal requirements. 

  • Level A: A baseline for basic accessibility for most users with disabilities.
  • Level AA: Expands on Level A, catering to a wider range of disabilities, including more severe ones.
  • Level AAA: Aims for maximum accessibility for all users, regardless of disability.
