With over a billion individuals worldwide living with some form of disability, integrating accessibility features across platforms such as iOS, Android, macOS, and Windows is a foundational aspect of creating inclusive, universal experiences. Today, more people than ever are using online services and websites for everything from shopping to learning. However, not everyone can access these services in the same way. That is why accessible features empower users with disabilities, facilitating interaction with digital content in previously unimaginable ways.

Yet, the presence of these features is not enough. The true litmus test of accessibility lies in meticulous testing, a process that ensures these functionalities are not only theoretically available but are practically usable, offering a seamless and enriching experience to all users, irrespective of their physical or cognitive abilities. This testing is vital for identifying and mitigating barriers, ensuring that technology serves as a bridge to inclusion rather than a barrier.

Read our article to find out how accessibility features and their thorough testing can create a more inclusive digital world for everyone.

Empowering Every User: Why It Matters

So, what exactly is accessibility testing? Imagine you are making sure that anyone can easily open every door in a building — whether they are with disabilities, carrying a heavy load, or have any other condition that might make a standard doorknob a challenge.

Accessibility testing helps ensure that people of all abilities can use the software. This includes those who are blind, have low vision, are deaf or hard of hearing, or have cognitive or motor disabilities. Such individuals utilize many types of assistive technology, from screen readers to sip-and-puff devices to speech recognition.

Examples of such software:

  • Speech Recognition Software — converts the spoken word into text, which is used to log into the computer;
  • Screen Reader Software — used to read the text displayed on the screen;
  • Screen Magnification Software — used to increase the scale of text and facilitate reading for visually impaired users.

Screen readers are specialized software applications designed to enable individuals who are blind or have low vision to access the content displayed on a computer screen through the use of speech synthesis or braille output. These tools interpret and vocalize the contents and layout of the screen, including text and control elements, to provide users with a comprehensive understanding of the interface. It is crucial to recognize, however, that the functionality of screen readers varies. Some may primarily focus on translating the site’s code into audible commands, such as Google’s ChromeVox, while others offer a more detailed auditory and visual feedback experience. This variance underscores the necessity of accounting for different screen reader capabilities in the accessibility testing to ensure compliance and inclusivity.

For example, those with hearing difficulties often rely on visual indicators to recognize these changes. A variety of tools, which are available at no cost, can assist in evaluating the range and loudness of audio outputs. Incorporating such tools into the testing strategy can enhance the detection of issues that may affect users with hearing impairments. Accessibility encompasses a broad spectrum of disabilities, affecting how individuals interact with websites and software.

Accessibility testing extends far beyond mere technical compliance. Here are some compelling reasons why incorporating it into the development process is paramount:

  • Moral and social responsibility. Accessibility testing ensures everyone has equal access to the opportunities and resources offered by the digital world.
  • Legal compliance. Many countries have established accessibility regulations for public-facing websites and software due to the European Accessibility Act. These regulations mandate specific accessibility standards to ensure equal access for individuals with disabilities.
  • Improved brand reputation. Demonstrating a commitment to accessibility portrays the brand as inclusive and socially responsible. This fosters trust and loyalty with a wider audience, potentially leading to increased brand recognition and positive customer sentiment.
  • Improved User Experience (UX) for all. Accessibility principles often lead to cleaner code, simpler interfaces, and a more intuitive user experience for everyone.
  • Reaching a broader market. A significant portion of the global population has some form of disability. By making the software accessible, companies tap into a vast and often overlooked market segment, potentially expanding customer base and driving business growth.

Accessibility testing can actually improve the product for everyone. Making a site or app accessible often makes it better for all users. Simpler navigation, clearer design, and more intuitive interfaces benefit everyone, not just those with specific accessibility needs.

In short, accessibility testing isn’t just a box to check. It is an essential part of creating digital products that truly serve everyone. By embracing accessibility from the start, we can build a more inclusive digital world that’s better for all of us.

Conducting Accessibility Testing: A Multi-Faceted Approach

There’s no single, one-size-fits-all approach to accessibility testing. Here are some effective methods to employ for a comprehensive evaluation:

  • Manual testing involves putting yourself in the shoes of users with disabilities by utilizing assistive technologies like screen readers and keyboard navigation tools. By navigating the website or applications using these tools, QA engineers can identify specific areas where usability might be compromised for users with visual, motor, or cognitive impairments.
  • Automated testing leverages the power of specialized software tools designed to scan digital products for common accessibility violations. This tool checks the HTML code for the correct use of accessibility attributes and helps detect most of the bugs that are difficult to identify manually. It can also efficiently identify basic accessibility issues like missing alt text or insufficient color contrast. However, it is important to remember that automated testing is not a replacement for manual testing, as some accessibility challenges may not be readily detectable by automated tools.
  • User testing with individuals with disabilities, including users with disabilities in the usability testing sessions, provides invaluable real-world feedback. This allows accessibility challenges that might not be apparent through other testing methods to be identified. By directly observing how users with disabilities interact with the product, the owner can gain valuable insights and make targeted improvements to enhance accessibility.
