Visual Testing (VT) Practice Exam 2025 - Free VT Exam Practice Questions and Study Guide

In Visual Testing, "screenshot comparison" specifically involves analyzing two images to identify visual differences between them. This process is crucial for ensuring that a user interface appears as intended across different versions of the application or after changes have been made. By comparing screenshots, testers can spot discrepancies in layout, colors, and element positioning, which could indicate unintended regressions or design issues. This method helps maintain a consistent and user-friendly visual experience, enabling teams to catch problems that may not be evident through traditional testing approaches, such as functionality testing or text comparisons.

The other processes mentioned, such as measuring performance differences, comparing text, or checking code accuracy, while important in their own right, do not directly pertain to the visual analysis aspect inherent in screenshot comparisons.
