We write unit tests, feature tests and even behavior tests for the websites and apps that we work on. But how do we ensure that changes to our Sass/CSS don't introduce unintended visual bugs into our app?

This talk explains Visual Regression Testing, why it is important, and how we've used it at PolicyGenius to ensure that we can confidently change our stylesheets without stressing about unintended style changes leaking into our app.

Speaker Ian Yamey will cover automated tests, visual diffs, headless browsers, and more!For full details check out his talk submission here.
