Hello Analytics,

A while ago I asked about the existence of any A/B-Testing Framework. I got to know (Thanks, Nuria!) that https://phabricator.wikimedia.org/T135762 is in preparation. However, I assume, that until this is in place, we need to use custom solutions which utilize EventLogging.
Event logging itself is pretty clear to me, but not the splitting/cookie logic.

Could anybody link me some examples for such a self implemented way to show users their assigned content and, if they are not assigned to a group yet, to assign users to A/B… bins?

Here's the code for MW-VE to add a proportion of new accounts to have VE on by default, used when slowly ramping up deployment or for an A/B test: https://phabricator.wikimedia.org/diffusion/EVED/browse/master/VisualEditor.hooks.php;7fe96fc2380743b4e63f4bb7c03e2ebf2b2e1038$964 — hope that helps.
