Wraith – Our front-end regression testing tool
Wraith is a front-end regression testing tool that we built to help identify bugs introduced by CSS changes during incremental development. It uses PhantomJS or SlimmerJS to take screenshots of two chosen environments, such as a sandbox or localhost and another environment, such as a live site. Once the two environments have been captured, imagemagick will output a diff image with highlighted changes to show any CSS changes. This allows for regression testing of front end changes across multiple sites using multiple resolutions.
