Learn everything about Accessibility testing, its advantages, disadvantages, tools and why is Accessibility testing important in this guide.
ADA testing, also known as Accessibility Testing, is the process of verifying that a website or application can be used by people with disabilities, including those who are visually impaired, hearing impaired, or have physical disabilities.
ADA testing is essential for any organization that wants to ensure that its digital products are accessible to everyone.
In this tutorial, we will cover the basics of ADA testing and provide a step-by-step guide to get you started.

What is Accessibility testing?
Accessibility testing is the process of evaluating a website, application, or digital product to ensure that it can be accessed and used by people with disabilities. The goal of accessibility testing is to identify and address any barriers that might prevent users with disabilities from accessing or interacting with a product.
Accessibility testing covers a wide range of disabilities, including visual, auditory, motor, and cognitive impairments. Some common examples of accessibility testing include:
- Testing the compatibility of a website or application with assistive technologies, such as screen readers, voice recognition software, or braille displays.
- Ensuring that all visual elements, such as images and videos, have alternative text that can be read by assistive technologies.
- Verifying that all form elements, such as input fields and buttons, have descriptive labels that can be read by assistive technologies.
- Testing the color contrast and font size to ensure that content is readable for users with low vision.
- Verifying that all interactive elements, such as buttons and links, can be accessed using only a keyboard.
- Ensuring that all multimedia content, such as videos and audio files, have closed captions and transcripts for users with hearing impairments.
Accessibility testing is essential for creating an inclusive digital environment and ensuring that all users, regardless of their abilities, can access and use a product. It can also help organizations avoid legal liabilities and improve their reputation by demonstrating a commitment to accessibility and inclusivity.
Why is Accessibility Testing Important?
accessibility testing is important for creating an inclusive digital environment, complying with legal requirements, improving the user experience, and providing business benefits. By prioritizing accessibility testing, organizations can ensure that their digital products are accessible to everyone and improve the overall quality and reach of their products and services.
Accessibility testing is important for several reasons:
- Inclusivity: Accessibility testing ensures that people with disabilities have equal access to digital products and services. Without accessibility testing, many users with disabilities would be excluded from using or interacting with digital products, which is not only unfair but can also limit their opportunities.
- Legal Compliance: Many countries have laws and regulations that require digital products to be accessible to people with disabilities. Failing to comply with these laws can result in legal liabilities, fines, and reputational damage.
- User Experience: Accessibility testing can improve the user experience for all users, not just those with disabilities. For example, adding alternative text to images not only makes them accessible to visually impaired users but also makes them more searchable and informative for all users.
- Business Benefits: By ensuring that digital products are accessible to everyone, organizations can expand their customer base and improve customer loyalty. In addition, demonstrating a commitment to accessibility can improve brand reputation and demonstrate a company’s commitment to social responsibility.
Tools used for Accessibility Testing
There are various tools available for accessibility testing, ranging from screen readers to automated testing tools. It is important to use a combination of tools to ensure that a website or application is accessible to users with disabilities.
Here are some of the most commonly used tools:
- Screen Readers: Screen readers are software applications that read aloud the content of a website or application to users who are visually impaired. Examples of screen readers include JAWS, NVDA, and VoiceOver.
- Color Contrast Analyzers: These tools check the color contrast of text and background colors to ensure that the content is readable for users with low vision. Examples of color contrast analyzers include WebAIM’s Color Contrast Checker and Accessible Colors.
- Keyboard Navigation Testing: Keyboard navigation testing tools simulate the use of a keyboard to navigate through a website or application. Examples of keyboard navigation testing tools include Keyboard Accessibility Checker and Tenon.io.
- Automated Accessibility Testing Tools: These tools automatically test a website or application for accessibility issues, such as missing alternative text, invalid HTML, and color contrast problems. Examples of automated accessibility testing tools include Axe, Google Lighthouse, and Wave.
- Manual Accessibility Testing: While automated tools can detect many accessibility issues, manual testing is still necessary to identify more complex accessibility problems. Manual testing involves using a combination of assistive technologies and expert judgment to evaluate the accessibility of a website or application.
What to test in Accessibility Testing?
Accessibility testing is a critical process that aims to ensure digital products are accessible to users with disabilities.
To achieve this goal, accessibility testing covers a wide range of areas, including but not limited to, visual design, keyboard navigation, multimedia, and compatibility with assistive technologies.
The primary objective of accessibility testing is to identify and eliminate any barriers that may prevent users with disabilities from accessing or interacting with a product. I
n this section, we will explore some of the key areas to test in accessibility testing and provide insights into how to perform these tests effectively.
1. Understand ADA Requirements
The first step in ADA testing is to understand the accessibility requirements. The Americans with Disabilities Act (ADA) requires that all digital products be accessible to people with disabilities. There are also international standards such as WCAG 2.1 that provide guidelines for accessible design.
2. Identify Testing Tools
There are various tools available to help you test for accessibility. Some popular tools include:
- Axe
- Wave
- AChecker
- Chrome Accessibility Developer Tools
- Screen Readers
3. Test for Keyboard Accessibility
Keyboard accessibility is an essential part of ADA testing. Many users with disabilities rely on keyboard navigation to interact with digital products.
Ensure that your website or application can be accessed using only a keyboard and that all interactive elements are reachable and operable.
4. Test for Screen Reader Compatibility
Screen readers are used by visually impaired users to navigate websites and applications.
To test for screen reader compatibility, use a screen reader such as NVDA or JAWS, and navigate your website or application.
5. Test for Color Contrast
Color contrast is important for users with low vision. Ensure that all text and visual elements have sufficient contrast to be easily read by users with low vision.
6. Test for Alternative Text
Alternative text, or alt text, is used to describe images to users who are visually impaired. Ensure that all images have descriptive alt text.
7. Test for Form Labels
Form labels are important for users with screen readers. Ensure that all form elements have descriptive labels that can be read by a screen reader.
8. Test for Video and Audio Accessibility
Videos and audio elements should have closed captions or transcripts to ensure that users with hearing impairments can access the content.
9. Test for Scalability
Ensure that all content and visual elements can be scaled up to accommodate users with low vision.
10. Document Results and Remediation
Document the results of your ADA testing, and develop a remediation plan for any issues found during testing. Addressing accessibility issues not only ensures that your website or application is accessible to everyone but also improves the user experience for all users.
ADA testing is an essential part of ensuring that your website or application is accessible to everyone. By following these steps and using the right testing tools, you can ensure that your digital products meet accessibility requirements and provide an inclusive user experience for all users.
