Visual testing
We use (and built) paparazzi as an automated parallel screenshot tool to have a birds eye overview of the site. This is invaluable when doing huge CSS changes then wanting to make sure nothing looks incredibly bananas afterwards.
Run yarn paparazzi to screenshot all pages, then check the screenshots in the /paparazzi folder. You can add any new routes you want to screenshot inside the .paparazzirc file in the project root.
