Overview

Visual regression testing captures screenshots of UI components and pages, then compares them across versions to detect unintended visual changes. This automated approach catches CSS bugs, layout issues, and design regressions that traditional functional tests miss.

When to Use

• Detecting CSS regression bugs
• Validating responsive design across viewports
• Testing across different browsers
