A Guide to Accessibility Testing: Ensuring Inclusivity in Digital Products
In today’s digital age, accessibility is no longer an optional feature for websites and applications — it’s a necessity. Ensuring that your digital products are accessible to all users, including those with disabilities, is not only a legal requirement in many regions but also a moral obligation. Accessibility testing plays a pivotal role in identifying and rectifying potential barriers that might hinder users’ access and interaction with your products. This guide will delve into the importance of accessibility testing, its key principles, methods, and best practices. Accessibility testing is a type of software testing used to test the application from the physically challenged person’s point of view. Here the physical disability could be old age, hearing, color blindness, and other underprivileged groups. It is also known as 508 compliance testing.
Why Accessibility Matters:
Accessibility goes beyond compliance; it’s about creating an inclusive digital environment that empowers everyone to access and use your products, regardless of their abilities. With approximately 15% of the world’s population living with disabilities, neglecting accessibility can mean excluding a significant portion of potential users.
For accessibility testing, there are some assured rules and regulations, which need to be followed as well.
The Law for Accessibility testing:
- Web content accessibility guidelines: These strategies are established to serve a purpose, which helps us to increase the user-friendliness of a website.
- Rehabilitation Act, section 504, and section 508:
Section 504: This section will help people with disabilities by providing workspace access, education, and other organizations.
Section 508: Section 508 will help those people by giving access to technology.
- Americans with disabilities act (ADA): The ADA rule says that all the domains, such as schools and organizations, public buildings should make the tools that everyone uses.
The international standards for coding and accessibility are the Web Content Accessibility Guidelines (WCAG), both versions 2.0 and 2.1. They are based on the following four foundational aspects, known as POUR, which are necessary for anyone to access and use web content:
1. Perceivable: Information and user interface components must be presentable to users in ways they can perceive. This includes providing text alternatives for non-text content such as images and videos.
2. Operable: User interface components and navigation must be operable, allowing users to interact effectively with the product. Keyboard navigation, clear focus indicators, and understandable controls are examples of operability.
3. Understandable: Information and operation of the user interface must be understandable. This involves using clear language, providing helpful error messages, and ensuring consistency in design and functionality.
4. Robust: Content must be robust enough that it can be reliably interpreted by a wide variety of user agents, including assistive technologies.
The WCAG presents evaluation standards for assessing your content, categorized into three levels of compliance. Each successive level incorporates the criteria of the previous level(s), demanding greater dedication to rectification and upkeep. Additionally, adhering to higher levels of compliance may influence the visual design to a greater extent.
The three levels of WCAG 2.0 conformance are:
- Level A: To meet this level, you have to meet 25 success criteria. For example, at this level, you can’t identify something by colors, such as in “Push the yellow arrow to proceed.”
- Level AA: To reach this level, you have to meet 13 additional success criteria — and those are on top of the 25 from Level A. An example of criteria at Level AA is meeting color contrast standards.
- Level AAA: This comes with an additional 24 success criteria (for a total of 62). Examples of achieving Level AAA success would be an enhanced level of color contrast or a removal of any element that blinks or flashes three times per second in order to decrease the likelihood of a user having a seizure.
Additionally, WCAG 2.1 adds more success criteria as follows:
- Level A: Five additional success criteria
- Level AA: Seven additional success criteria
- Level AAA: Five additional success criteria
Methods of Accessibility Testing:
Manual Testing: Conducting manual tests involves human testers using assistive technologies like screen readers and voice commands to navigate through your product. This method allows for a nuanced assessment of user experience.
Automated Testing: Utilizing automated tools can help identify common accessibility issues quickly. These tools scan your website or application for violations of accessibility standards and provide a list of potential issues. However, they might miss certain complex issues that require human judgment.
User Testing: Collaborating with actual users with disabilities is invaluable. Their feedback provides insights into real-world experiences, helping you address specific pain points.
There are different ways of Testing Accessibility based on the disability.
Best Practices for Effective Accessibility Testing:
- Early and Continuous Testing: Integrate accessibility testing from the initial design phase and throughout the development process. This prevents issues from accumulating and becoming harder to fix later.
- Use Realistic Content: Test with authentic content, including images, videos, and text. This mirrors real user experiences more accurately.
- Test Various Assistive Technologies: Different disabilities require different assistive technologies. Ensure your testing covers a range of these tools, such as screen readers, magnifiers, and voice recognition software.
- Document and Prioritize Issues: Create a comprehensive accessibility testing checklist and document all issues encountered. Prioritize fixing critical issues that severely impact usability.
Conclusion:
Inclusivity should be at the core of every digital product development process. Accessibility testing is the bridge between creating products and ensuring they’re usable by all individuals, regardless of their abilities. By adhering to accessibility principles, employing multiple testing methods, and incorporating best practices, you not only meet legal requirements but also demonstrate a commitment to building a more accessible and inclusive digital landscape.
