Accessibility Testing

What is Accessibility Testing?

Accessibility testing is the process of evaluating web and mobile applications to ensure they are easily usable by people with disabilities, such as visual, hearing, mobility, and cognitive impairments. This type of testing aims to create an inclusive digital environment by addressing any accessibility barriers and adhering to established accessibility standards and laws, such as WCAG Compliance.

How to Conduct Accessibility Testing

To conduct accessibility testing, follow these steps:

  • Identify the disabilities to support, such as vision, physical, cognitive, literacy, and hearing disabilities.
  • Perform manual testing by working with disabled people to understand their challenges and needs.
  • Perform automated testing using accessibility testing tools like Wave, TAW, Accessibility Developer Tools, and others.
  • Follow accessibility guidelines and best practices to make the application more accessible and user-friendly.
  • Design the website with accessibility in mind from the beginning.
  • Use appropriate color contrast and font sizes for better readability.
  • Ensure proper keyboard navigation and visible focus indicators.
  • Provide alternative text for images, audio, and video content.
  • Make forms and controls accessible using proper labels, ARIA attributes, and keyboard support.
  • Test the application with assistive technologies and incorporate feedback from disabled users.

Benefits of Accessibility Testing

Accessibility testing offers numerous benefits for businesses, including legal compliance, inclusivity, and brand awareness.

  • Legal compliance: Ensures applications comply with government regulations and acts, helping businesses avoid potential lawsuits and demonstrate a commitment to equal access.
  • Inclusivity: Creates a disabled-friendly software product that caters to a larger market, including the 20% of the population with disability issues.
  • Brand awareness: Demonstrates a commitment to inclusivity, enhancing brand reputation and appeal to a wider audience.
  • Cost savings: Automating accessibility testing reduces the overall time it takes to run tests and eliminates the need for manual non-functional testing, leading to cost savings.
  • Improved SEO: Ensuring web and mobile apps are accessible can improve the overall user experience and potentially lead to better search engine rankings.
  • Adoption of inclusive design principles: Promotes the use of design practices that make applications accessible to all users.
  • Compatibility with assistive technologies: Ensures apps are usable with screen readers, speech recognition software, and screen magnification, improving accessibility for users with disabilities.

Common Tools for Accessibility Testing

Common tools for accessibility testing can help developers identify and address issues in their web and mobile applications, ensuring a more inclusive user experience. Some popular accessibility testing tools include:

  • WAVE: A web accessibility evaluation tool that provides visual feedback on potential accessibility issues and offers suggestions for improvement.
  • Accessibility Developer Tools: A Google Chrome extension that helps developers identify and fix accessibility issues in their web applications.
  • TAW: A web-based tool that analyzes websites for accessibility issues based on WCAG guidelines.
  • BrowserStack Accessibility Testing Tool: A single platform to identify basic and complex accessibility issues quickly, offering features like Workflow Scanner, Assisted Tests, and Screen Readers on Real Devices.
  • Perfecto: A platform that supports accessibility testing with VoiceOver and TalkBack, offering unified testing, advanced automation, and full toolchain integration.

Overcoming Accessibility Testing Challenges

Overcoming accessibility testing challenges involves a combination of strategies and best practices. To ensure compliance with accessibility standards and laws, follow established guidelines like WCAG. Cater to diverse user needs and disabilities by involving different teams in the testing process and using a mix of manual and automated testing methods. Balance accessibility with design and functionality by adopting inclusive design principles, such as proper labels for assistive technologies, text contrast, hit area size, view hierarchy, and dynamic font sizes.

Keep up with evolving technologies and guidelines by continuously monitoring and improving accessibility. Collaborate between developers and testers using unified platforms that offer advanced automation capabilities and integrate with accessibility tools. By addressing these challenges, businesses can create inclusive digital environments, cater to a larger market, comply with legal requirements, and improve the overall user experience.
