Visual Testing (VT) Practice Exam 2026 - Free VT Exam Practice Questions and Study Guide

Visual regression tests are specifically designed to confirm that there are no unintended changes in the visual aspects of an application after code modifications. This involves comparing the new versions of the application's user interface with previous versions to identify any discrepancies, such as changes in layout, colors, or other visual elements that may not directly impact functionality but can affect user experience.

When developers make updates or changes to code, visual regression testing ensures that these adjustments do not inadvertently alter the look and feel of the application, preserving consistency and usability. This is crucial in maintaining the integrity of the user interface as it evolves, especially in larger projects where multiple team members may contribute code changes that could affect visual presentation.

While other purposes such as performance assessment, feature functionality testing, and improving build processes are important in a software development lifecycle, they do not specifically address the visual fidelity of an application in the way that visual regression testing does.
