Visual Regression Testing with BackstopJS
Speaker: David Needham
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 session, 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.
