Drupal Europe 2018

Drupal Europe (10-14 September 2018) is both a technology conference and a family reunion for the Drupal community. It brings together 1600+ attendees with shared interests in great digital experiences and solving challenges together.

Visual Regression Testing with BackstopJS

Tuesday, September 11th, 4 pm – 6 pm

How do you tell if a change you made to your website has unintended side effects? Security updates should rarely result in anything changing visually, but how can you be sure?

Visual regression testing automates the comparison process by taking screenshots of two URLs and comparing them. You can view a report that highlights the differences and use the pass/fail result to make decisions.

In this workshop, we will use the BackstopJS visual regression tool locally, via Node JS, to automate visual QA. We will also learn how to scale and automate these tests across multiple sites and URLs.
