Visual testing is a method used to check the appearance and layout of software applications to ensure they look and work as intended. It focuses on comparing the visual aspects of an application against expected results, verifying that elements such as text, images, and layouts appear correctly.
The purpose of visual testing is to detect any visual issues that might not be caught by traditional functional tests. It ensures that the application's user interface is visually consistent and free of defects, which is crucial for providing a positive user experience.
Visual testing works by capturing screenshots or visual representations of the application at different stages. These images are then compared to predefined baseline images to identify any differences. This process helps spot discrepancies or unexpected changes in the application's appearance.
Visual testing is an essential practice for ensuring that software applications appear correctly and meet design expectations. By focusing on the visual aspects of an application, it helps maintain a consistent and user-friendly interface, improving overall user satisfaction.
