What does "screenshot comparison" help identify in a visual testing process?

Screenshot comparison is critical in the visual testing process as it allows teams to identify discrepancies in layout, color, or design elements between a baseline version of the application and its current state. This form of testing captures the visual aspects of an application, ensuring that any unintended changes, such as misaligned elements, incorrect color schemes, or altered typography, are detected.

Visual testing is particularly important for maintaining a consistent user experience, as even minor visual changes can significantly impact user perception and usability. By comparing screenshots, testers can pinpoint visual regressions that may occur due to code updates or design changes, helping maintain high standards in the visual aspects of an application over time. This thoroughness in checking visual fidelity ensures that the product not only functions correctly but also adheres to branding and design guidelines, ultimately contributing to a better user experience.
