My website has a test suite with visual regression tests; screenshot different webpages and compare against a set of expected images: https://github.com/twolfson/twolfson.com/tree/3.40.0/test/perceptual-tests/expected_screenshots This weekend, I switched it from PhantomJS to node-webkit and am happy with the results: Benefits node_modules/ always work (e.g. no process is undefined issues) node_mod
