Automating visual regression testing is a critical step to ensure that your application’s user interface (UI) remains consistent after updates. It helps detect any unintended visual changes that might have been introduced during development or deployments. Here’s an overview of the tools and techniques used in visual regression testing automation:

What is Visual Regression Testing?

Visual regression testing ensures that visual elements of a web application (like layout, fonts, colors, and UI components) appear the same across different versions. It compares a baseline image (or screenshots) with the current version of the UI to identify visual differences.

Why Automate Visual Regression Testing?

• Consistency: Ensure that new features or bug fixes don’t break the UI.
• Faster Feedback: Developers get immediate feedback about visual issues.
• Cross-browser Testing: Ensure UI consistency across multiple browsers and devices.
• Cost-Effective: Automation reduces manual effort and time in the long run.
