What Do We Know About Accessibility (A11y) Testing?
This type of testing is specifically designed for users with disabilities. A11y testing ensures that a website, application, or any digital content is easily understandable and that users can navigate different components without too much trouble.
There are standards in the market that every company must follow to ensure that their product has zero A11y bugs and can be used by users with disabilities. The Web Content Accessibility Guidelines (WCAG) is the recommended standard for executing A11y testing.
We will learn more about these standards and the importance of A11y testing further in the blog.
Why is it so Important That Every Company Executes A11y Testing?
Incorporating accessibility testing is not just about following regulations—it’s about creating an inclusive digital experience that benefits both businesses and users. Here’s why companies should prioritize A11y testing:
Compliance with Regulations
In many countries around the globe, executing accessibility testing is required by law. Countries such as the US, the UK, and those in the EU have taken significant steps to ensure that every company operating within their region follows these regulations and makes their product user-friendly for individuals with disabilities.
Larger Customer Base
Recent market research found that over 1 billion people worldwide have some form of disability. If a company implements effective A11y testing, it can significantly expand its target audience.
Social Impact Initiatives
Ensuring A11y in a product not only helps reach a wider audience but also sends a strong message about the company’s commitment to equality and diversity. Such initiatives never go to waste and always benefit the company in the long run.
Better User Engagement
A11y benefits not only users with disabilities but also improves the overall user experience for everyone. Implementing accessibility testing results in structured content, clearer buttons, and accurate navigation. The benefits go far beyond these, making the product more user-friendly for all.
Key Components of Accessibility Testing
To create a truly inclusive digital experience, companies need to focus on the following essential aspects of A11y testing:
This is one of the key components of accessibility testing as it ensures that the platform is accessible across various devices, from desktops to mobile phones (Android/iOS). Most importantly, it offers a stable and consistent user experience.
Navigating Using Keyboard Keys
Users with motor disabilities often find it difficult to navigate between different elements on a page. Accessibility testing ensures that users can move between elements easily using a keyboard instead of a mouse.
Graphic Components and Color Contrast
Users with visual impairments rely on color contrast between text and background colors to read content more easily. Proper contrast improves accessibility and ensures better readability.
Use of Screen Readers (VoiceOver, NVDA, & JAWS)
It is essential to test how content is narrated using screen readers to assist users with visual impairments.
Time-Dependent Content
Applying accessibility testing and resolving related issues allow users to have ample time to interact with time-sensitive content.
Clear and useful instructions in forms help users with disabilities complete them without errors. Many users struggle with form submissions due to unclear requirements, but accessibility testing helps resolve such issues, making the form-filling experience smoother.
Principles of Accessibility Testing
To build truly inclusive digital platforms, accessibility testing follows key principles that ensure usability for all individuals:
Solid
The content on the platform must be structured so that it is easily interpreted by assistive technologies.
Visible
The presentation of content and UI components should be clear and easy to understand for a diverse audience.
Functional
The UI and all other product components should be fully functional for all users. Interactive elements must be accessible via keyboard.
Transparent
The data and UI should be intuitive and easy to understand. Every component should be consistent and provide clear instructions to users.
WCAG Guidelines and Their Benefits
The WCAG is a global standard ensuring that web content is usable and accessible for individuals with disabilities.
There are three levels of accessibility compliance:
Level A (Basic)
This is the most fundamental level that all websites must follow. The checklist includes ensuring users can easily navigate between elements and that alternative text for images is provided.
Level AA (Mid-Range)
This level covers aspects such as logical page structure and contrast ratios. Level AA is more advanced and requires A11y tools for testing.
Level AAA (High-Level/Most Advanced)
This level requires meeting all Level A and AA criteria, along with additional requirements for rare or specific disabilities.
Best Practices for Implementing Accessibility Testing
Implementing accessibility testing requires a combination of best practices and the right tools to ensure that products meet accessibility standards. Below are some of the best practices that companies can follow:
Start Early
Accessibility testing should be integrated into the development process from the very beginning. This proactive approach helps identify and resolve issues early on rather than dealing with them at later stages. Ensuring accessibility from the start leads to a more seamless and efficient design and development process.
While manual testing is important, automated tools can speed up the process and catch common accessibility issues. Tools like Axe, WAVE, and Lighthouse scan websites and applications for accessibility errors and provide detailed reports. These tools can help identify violations of WCAG guidelines, such as insufficient color contrast or missing alt text for images.
Automated tools can catch many issues, but they cannot replace human judgment. Manual testing is essential, especially when it comes to complex interactions or evaluating the overall user experience. Testers should navigate websites or applications using only a keyboard, check for screen reader compatibility, and ensure that content is structured logically.
Involve Users with Disabilities
One of the most important steps in accessibility testing is to involve real users with disabilities. They can provide firsthand feedback on how well a product meets their needs. User testing can highlight issues that may not be immediately apparent to developers or testers, ensuring that the product works as intended for everyone.
Continuous Monitoring and Updates
Accessibility should not be a one-time effort. As websites and applications evolve, so too should their accessibility features. Continuous monitoring and testing ensure that new content, features, or design updates do not introduce any accessibility barriers. Regular audits help maintain compliance with accessibility standards and provide ongoing improvements to the user experience.
Training and Awareness
Educating employees, especially designers and developers, on the importance of accessibility is crucial. When the team understands the needs of users with disabilities, they are better equipped to design and develop inclusive products. Offering regular training on accessibility standards and guidelines keeps the team updated on best practices and emerging trends in accessibility.
Conclusion
To summarize, we now understand the importance of accessibility testing, its key components, and how organizations can ensure their products are inclusive. Accessibility testing ensures that digital content is not only for users without disabilities but for everyone. As humans, it is our responsibility to ensure that no user feels excluded.
