Backstop Generator Module: Easy BackstopJS Configuration Generator for Drupal 8

Visual regression testing is an incredibly helpful tool in any developer’s toolbox, making it possible to programmatically check for unexpected CSS changes on a given website.

One of the most time consuming parts of running visual regression tests with BackstopJS, however, is building an exhaustive configuration file that includes enough Backstop “scenarios” for a lot of the content on a site.

In pursuit of simplifying that process, I’ve created a new Drupal 8 module called “Backstop Generator”. Backstop Generator will help you scaffold out a Backstop configuration file by letting the user select a combination of specific whitelisted pages (i.e. “Homepage”, “About us”, “Contact”), as well as a predetermined number of random pages to build a representative sample of their site automatically.
