Vulture is a CLI tool designed to automate visual regression testing by comparing screenshots of web pages. Vulture captures screenshots of two URLs at multiple resolutions and generates a "diff" image highlighting visual differences. It's ideal for developers, testers, and designers who want to ensure consistency across different versions of a website or between different environments.

• Cross-Platform: Works seamlessly on Windows, Linux, and macOS.
• Flexible Comparison: Compare two URLs side-by-side or monitor changes over time.
• Customizable Resolutions: Supports multiple screen resolutions for responsive testing.
• Integration-Ready: Easily integrates with CI/CD pipelines for automated visual testing.
• Comprehensive Reporting: Generates an HTML report to visually display differences.

You can install Vulture from RubyGems or GitHub Packages.

To install the latest version from RubyGems, run:

gem install vulture

gem install vulture -v [version-number] (e.g., 1.0.0)

To install Vulture from GitHub Packages, you'll need to authenticate with GitHub and add GitHub Packages as a source. Add the following to your .gemrc file:

---
:backtrace: false
:bulk_threshold: 1000
:sources:

- https://rubygems.pkg.github.com/zeusssz
:update_sources: true
:verbose: true

Then, run:

gem install vulture --source=https://rubygems.pkg.github.com/zeusssz
