Visual Testing is a software testing technique that focuses on verifying the visual appearance of an application. It ensures that the user interface (UI) looks and functions as intended across different devices and screen sizes. This type of testing helps identify issues like misaligned elements, incorrect colors, or missing images that could affect user experience. In Visual Testing, automated tools capture screenshots of the application and compare them against a baseline. Any differences are flagged for review, allowing testers to quickly spot visual discrepancies. This process is essential for maintaining a consistent and appealing UI, especially in web development and mobile applications.
