What Is Accessibility Testing?

Accessibility testing is the process of evaluating digital products to ensure they can be used by people with disabilities. This includes identifying barriers that may prevent users from accessing or interacting with websites, web applications, or mobile applications.

Accessibility testing focuses on users who may rely on assistive technologies or alternative interaction methods, such as:

• Screen readers
• Keyboard-only navigation
• Voice input tools
• Magnification software

The goal of accessibility testing is to ensure that digital interfaces are usable regardless of how users access them.

Most accessibility testing practices are guided by the Web Content Accessibility Guidelines (WCAG), which define standards for making digital content accessible. These guidelines are built around four core principles:

• Perceivable - Information must be presented in ways users can perceive
• Operable - Interfaces must be navigable using different input methods
• Understandable - Content and interactions must be easy to comprehend
• Robust - Content should work reliably with assistive technologies

By evaluating digital products against these principles, accessibility testing helps development and QA teams identify usability barriers and improve the overall accessibility of digital platforms.

Best Practices in Accessibility Testing

Accessibility testing is most effective when it is integrated throughout the product development lifecycle rather than treated as a final compliance step. Following structured accessibility testing practices helps teams identify barriers early and improve digital usability across platforms.

Below are several widely adopted best practices that help development and QA teams conduct accessibility testing more effectively.

1. Test Accessibility Early in the Development Process

Accessibility testing should begin during the early stages of product development. Waiting until the final testing phase often makes accessibility issues harder and more expensive to fix.

Accessibility checks can be introduced during:

• Design validation
• Development workflows
• Automated testing pipelines
• Pre-release quality assurance

When accessibility is evaluated early, teams can identify structural accessibility issues before they become deeply embedded in the product.

2. Combine Automated Testing with Expert Review

Automated accessibility tools help detect common accessibility violations quickly, but they cannot fully evaluate usability or interaction patterns.

Effective accessibility testing often includes:

• Automated accessibility scanning
• Assistive technology testing
• Keyboard navigation testing

Combining automation with expert evaluation helps teams identify both technical accessibility violations and usability-related accessibility barriers.

3. Test with Assistive Technologies

Accessibility testing should include validation using assistive technologies that many users rely on when interacting with digital products.

Common assistive technologies used during testing include:

• Screen readers such as JAWS, NVDA, or VoiceOver
• Keyboard-only navigation
• Voice control tools
• Magnification software

Testing with these tools helps teams understand how users with disabilities interact with digital interfaces and identify accessibility issues that automated tools may not detect.

4. Validate Accessibility Across Different Devices

Digital platforms often operate across multiple environments. Accessibility testing should ensure that accessibility standards are maintained across these different contexts.

Testing environments may include:

• Desktop browsers
• Mobile devices
• Web applications
• Responsive layouts

Ensuring accessibility across devices helps maintain consistent usability regardless of how users access the platform.

5. Evaluate Real User Workflows

Accessibility testing should not focus only on individual components. It should also evaluate how users navigate through complete workflows within the product.

Examples of workflows to evaluate include:

• User registration and login
• Form submission processes
• Navigation across application pages
• Transaction or checkout flows

Testing full workflows helps identify accessibility barriers that may appear during real user interactions.

6. Include Accessibility Testing in CI/CD Pipelines

Integrating accessibility testing into continuous integration and deployment workflows allows teams to detect accessibility issues automatically as new code is introduced.

Accessibility checks can run during:

• Code commits
• Build processes
• Automated test execution
• Deployment pipelines

This approach helps teams maintain accessibility standards consistently across releases.

7. Consider the Global Accessibility Audience

Accessibility testing should also account for the scale of users who rely on accessible digital experiences.

According to the World Health Organization (WHO), an estimated 1.3 billion people; about 16% of the global population live with some form of significant disability, meaning roughly 1 in every 6 people worldwide may face barriers when interacting with inaccessible digital platforms.

Accessibility challenges remain widespread across the web as well. According to the WebAIM Million Report, 94.8% of the top one million websites still contain detectable WCAG accessibility failures, highlighting how common accessibility barriers remain across modern digital platforms.

Accessibility also has economic implications. Research referenced by the World Economic Forum estimates that people with disabilities and their families represent more than $13 trillion in annual global spending power.

Considering the scale of users affected by accessibility barriers reinforces why accessibility testing should be treated as a core part of digital product quality rather than a secondary compliance activity.

8. Monitor Accessibility Over Time

Accessibility is not a one-time activity. As digital platforms evolve, new accessibility issues may appear.

Organizations should periodically review accessibility across their platforms through:

• Regular accessibility audits
• Automated accessibility scans
• Accessibility regression testing

Continuous monitoring helps ensure accessibility remains consistent as products evolve and new features are introduced.

Accessibility testing is most effective when it becomes a continuous part of product development rather than a final validation step. Combining automation, assistive technology testing, and structured evaluation helps teams identify accessibility barriers earlier and improve overall digital usability.

Following these best practices allows organizations to build digital platforms that are more inclusive, compliant, and reliable for a broader range of users.

Common Accessibility Testing Mistakes to Avoid

While many teams recognize the importance of accessibility testing, it is often implemented incorrectly or too late in the development process. These mistakes can lead to accessibility barriers remaining unresolved even when testing tools are used.

‍

Understanding common accessibility testing mistakes helps teams build more effective testing strategies and improve accessibility outcomes.

1. Treating Accessibility as a Final Testing Step

Accessibility testing is sometimes performed only at the end of the development cycle. When testing happens this late, accessibility issues may already be deeply integrated into the interface design and code structure.

This approach often results in:

• Expensive remediation efforts
• Delayed product releases
• Incomplete accessibility fixes

Accessibility testing should instead be integrated throughout the product lifecycle, beginning during design and continuing through development and testing phases.

2. Relying Only on Automated Testing Tools

Automated accessibility tools are useful for identifying many common accessibility violations, but they cannot detect every accessibility barrier.

Automated tools typically detect issues such as:

• Missing alternative text
• Color contrast failures
• Improper markup structure

However, they cannot fully evaluate usability, reading order, interaction flows, or assistive technology behavior. A more comprehensive accessibility strategy includes automated tools alongside broader evaluation methods.

3. Ignoring Real User Interaction Flows

Accessibility testing sometimes focuses only on individual page elements rather than complete user journeys. This can cause accessibility barriers to remain hidden within complex workflows.

Common workflows that should be tested include:

• User onboarding processes
• Multi-step forms
• Checkout or transaction flows
• Account management features

Testing full workflows helps ensure that accessibility is maintained throughout the entire user experience.
