The Complete Guide to QA Accessibility Testing in 2025

According to the World Health Organization, approximately 1.3 billion people, or 16% of the global population, experience significant disabilities. These disabilities can range from visual and auditory impairments to cognitive and motor challenges, affecting how individuals interact with digital content.

That is why a massive group often struggles to access digital content due to poor design and a lack of accessibility measures. Common issues include low-contrast text, missing alternative text for images, and unlabeled form inputs, which can hinder usability for people with disabilities. However, accessibility testing plays a crucial role in identifying and addressing these barriers, ensuring that web applications are usable by everyone, regardless of their abilities.

In this blog, we'll explore the latest trends in accessibility testing, the challenges faced by customers, and the solutions provided by QASource.

What Is QA Accessibility Testing?

QA accessibility testing is a quality assurance process that verifies whether digital content like websites, mobile apps, and software is usable by people with various disabilities. It ensures that users with vision, hearing, mobility, or cognition impairments can access, navigate, and interact with digital interfaces effectively. It is performed to ensure that the product meets various accessibility standards like WCAG(Web Content Accessibility Guidelines) and Section 508 (U.S. federal accessibility requirement)

Unlike general QA, which focuses on functionality, performance, and security, accessibility testing specifically targets usability for assistive technologies such as:

• Screen readers (e.g., JAWS, NVDA)
• Keyboard-only navigation
• Voice recognition software
• Braille terminals

Key Objectives of QA Accessibility Testing

• Compliance with standards like WCAG 2.1/2.2, Section 508, ADA (Americans with Disabilities Act)
• Inclusive design for all users, regardless of disabilities
• Detection of barriers such as poor contrast, missing alt text, and inaccessible form fields
• Avoid potential lawsuits due to non-compliance with accessibility laws.
• Make accessibility a continuous part of the software development lifecycle
• Verification of compatibility with assistive technologies

Why is Accessibility Testing Crucial in 2025?

In 2025, accessibility testing will become a core requirement for digital products. It’s no longer a “nice-to-have”; it’s essential for compliance, usability, and business success.

1. Legal Compliance Is Non-Negotiable

   Laws now mandate accessible digital experiences. The ADA applies to websites and apps. In 2023, there were over 4,600 accessibility lawsuits in the U.S. alone (UsableNet). Europe and other regions have similar laws. Non-compliance can lead to fines and reputational damage.

2. Everyone Deserves Equal Access

   Digital services must work for all users. That includes people with vision, hearing, mobility, or cognitive challenges. Accessibility testing helps identify and fix barriers. It ensures that no one is left out.

3. Accessibility Improves User Experience

   Good accessibility supports all users. It helps people with temporary injuries, older adults, and those on slow connections. Simple features like readable fonts and clear navigation benefit everyone. These improvements also enhance SEO and site performance.

4. AI and Automation Boost Efficiency

   AI tools are changing how teams test. They simulate users, scan for WCAG issues, and suggest fixes. This speeds up testing and reduces manual work. It also helps catch issues earlier in the development cycle.

5. Integral part of Quality Assurance

   Accessibility is now part of standard QA. For example, teams must test for usability when checking for bugs or performance. Accessible products are more reliable, usable, and inclusive.

Digital Accessibility Rules and Regulations

Accessibility testing isn't just a nice-to-have best practice—it's the law. The government is on the side of the people in ensuring that all technologies, including web-based and mobile applications, are accessible to all.

• Americans with Disabilities Act Section III: This law requires that all domains, such as schools, organizations, and public buildings, be accessible to everyone, including web-based applications and technology.
• Title II of the ADA: This law enforces that all programs, services, and activities provided by state and/or local governments are accessible to everyone, including web-based applications and technology.
• Sections 504 and 508 of the Rehabilitation Act of 1973: Section 504 requires that reasonable accommodations be available for people with disabilities within the workplace, educational institutions, and organizations. Section 508 establishes requirements to be met by these institutions so that technology is accessible to everyone.

Web Content Accessibility Guidelines (WCAG): These protocols provide accessibility testing examples and recommend types of accessibility testing so that development and QA teams can discover ways to improve application accessibility. WCAG recommends the following four main principles:

• Perceivable: All users can comprehend all displayed information being depicted, including how to use the application's user interface.
• Operable: All users can navigate all interface components without issues or barriers.
• Understandable: All users can understand all displayed information being presented, including how to navigate through the user interface of an application.
• Robust: All users can reliably interpret content within an application through assistive technologies.

What Should Accessibility Testing Address?

Knowing how to do accessibility testing starts by examining the types of disabilities that require enhanced support throughout your application. Your accessibility test cases should confirm that your product can provide a seamless experience for everyone, including those with the following disabilities:
