Visual Regression Testing

Visual Regression Testing is a software testing technique that detects unintended changes in a user interface by comparing current screenshots or rendered pages against approved baseline images. It is used to identify visual differences such as layout shifts, missing elements, styling changes, font issues, or rendering inconsistencies across browsers and devices. Teams often integrate visual regression tests into CI/CD pipelines to catch UI defects before release.
