Are you looking to expand your vision for Accessibility Testing Chrome? You can easily choose a third-party tool from the hundreds of options available in the market. This inclusion will help you improve your site’s web accessibility. As we all know, web accessibility standards ensure that websites are usable by everyone, including those with specific disabilities.
Although Chrome DevTools provides some built-in accessibility features, third-party tools will further expand these to generate more effective results. In this article, we will mention these tools and their features, benefits, and the process of integrating them into the web development workflow.
Understanding Web Accessibility
Before we explore the third-party options for integrating web accessibility, let us shift our limelight toward the basics of web accessibility testing. This process refers to the addition of inclusive practices for removing barriers that prevent interactions with or access to websites by persons with specific disabilities.
If you follow the correct practices for designing, developing, and editing your websites, all of your users will have equal access to the information and functionality of these websites.
The Importance of Web Accessibility
Now that we have understood the basics of web accessibility let us shift our focus toward some of the most important factors that justify the inclusion of web accessibility standards, keeping in mind the modern requirements of the app development and testing industry:
- It is unknown to none that most nations have stringent laws and regulations that enforce the implementation of web accessibility. Some of the most important laws include the Americans with Disabilities Act (ADA) in the United States and the Web Content Accessibility Guidelines (WCAG) implemented globally.
- The latest survey from a very reputable organization shows that almost 15% of the total world population has some sort of disability. So, implementing accessible websites can help app-developing companies broaden their target audience massively.
- Websites that have proper accessibility standards often offer enhanced Search Engine Optimizations. This implementation also helps the testers improve the website’s visibility in the search results.
- All the features that help to improve the accessibility of a website, including improved navigation, also help enhance the website’s overall user experience.
Limitations of Chrome DevTools for Accessibility Testing
Chrome DevTools is a compelling suite for implementing web development. This suite also offers several accessibility features, including the ability to inspect the accessibility tree, audit for issues using Lighthouse, and simulate different color vision deficiencies. However, the accessibility standards of Chrome DevTools are massively limited in the following segments:
- DevTools might not cover all the accessibility issues available in the current market. This obstacle is permanently visible for those who require a more nuanced understanding.
- DevTools does not offer comprehensive features for automating the accessibility test cases compared to other specialized tools readily available in the present market.
- Regarding test reporting, DevTools does not generate comprehensive test reports for accessibility test cases. These reports do not show the issues currently available in the application and their possible resolutions.
- Using Chrome DevTools to implement accessibility testing will severely limit the integration with other development and testing workflows.
To address these limitations, testers and developers can utilize third-party tools to implement web accessibility.
