This presentation and demo code was created for the TYPO3 User Group Chemnitz/Südwestsachsen, hosted by https://www.dmk-ebusiness.de/ in February 2023.
Come and join us! https://www.meetup.com/de-DE/typo3-usergroup-chemnitz-sudwestsachsen/
A little setup hint: I run BackstopJS locally for my tests, not inside a container. If you want to run it fully virtualized, you might have to take a look at https://hub.docker.com/r/backstopjs/backstopjs/
My used code: https://gist.github.com/akiessling/f57bdf10b9f90431a8aa502db437de2f
