WAVE (Web Accessibility Evaluation Tool) is a popular tool for automated accessibility testing of websites. It was developed by WebAIM and offers a variety of functions to evaluate the accessibility of web content.

Here are some features and benefits of automated testing with WAVE:

Quick Review: WAVE allows users to quickly perform an accessibility review of a website without having to manually go through every aspect.
Easy to use: The tool is designed to be user-friendly and requires no technical knowledge. Users can simply enter the URL of the website to be checked and receive the report.
Comprehensive reports: WAVE generates detailed reports on website accessibility, including warnings, errors and tips on how to improve.
Visual inspection: In addition to analyzing the HTML code, WAVE also provides a visual inspection of the web page to identify issues that may not be detected by the code alone.
Interactive tools: The tool offers interactive functions such as the ability to check color contrasts, improve the readability of text and analyze alternative texts for images.
Integration with developer tools: WAVE can be integrated into browser developer tools, allowing developers to check the accessibility of their websites during the development process and fix errors immediately.
Available for free: WAVE is free and publicly available, making it a popular tool for developers, designers and testers concerned about the accessibility of their web projects.

Although automated testing with WAVE provides a quick way to check the accessibility of websites, it is important to note that automated tools cannot cover all aspects of accessibility. Manual checks and user testing are also crucial to ensure that a website is accessible to all users.
