PhantomCSS is a CasperJS module for visual/CSS regression testing that captures screenshots with PhantomJS or SlimerJS and compares them against baseline images using Resemble.js, generating image diffs on failure. It is explicitly unmaintained as of December 2017.

Use cases

  • catch unintended CSS changes in web UIs
  • visual regression testing for style guides
  • screenshot diff testing for responsive layouts
  • compare rendered pages against baseline images
  • test web app components for pixel-level regressions

When to choose

  • maintaining a legacy test suite already built on PhantomCSS
  • working with an old PhantomJS/CasperJS-based testing stack

When to avoid

  • starting a new visual regression testing project
  • modern browser environments (PhantomJS is deprecated)
  • projects needing maintained tooling or support
