Name a popular tool used for automated visual testing.

Automated visual testing tools are specifically designed to capture and compare visual content of applications, helping to ensure that the user interface appears as intended across different browsers and devices. Applitools and Percy are two of the leading tools in this domain. They utilize advanced image comparison techniques to detect visual discrepancies, making them highly effective for maintaining UI consistency and quality.

While other tools like Selenium are powerful for functional testing (ensuring that an application behaves as expected), they do not focus on visual testing itself. Similarly, Jira is a project management tool, and Postman is primarily used for API testing. Therefore, the distinction lies in the ability of Applitools and Percy to handle visual comparisons explicitly, making them the relevant choice for automated visual testing.
