BackstopJS: Detailed Overview & Metrics
BackstopJS is a visual regression testing tool for web applications. It allows developers to compare visual differences between different versions of a website or web application to identify any unintended changes. BackstopJS captures screenshots of web pages and compares them pixel by pixel to detect any visual discrepancies, helping ensure consistent UI across releases.
Compared to other visual regression testing tools like Percy or Applitools, BackstopJS is open-source, easy to set up, and provides a flexible configuration for testing various scenarios. It is actively maintained with regular updates and community support.
