I am creating a solution that permit other app editor to sent notifications to their app through Firebase Cloud Messaging, and I want to develop the possibility to do A/B Testing. I came across the groups syteme of FCM and, if that works, it would be a good way to separate audiences in two or three groups, as it is possible to register several devices at the same time in a group. However it seems to be designed to represent the devices of a single user, which means a small number of devices. So my question is, can we still use FCM grouping with a large number of devices (in the tens of thousands) ? Or can they not be used this way?

I realize you asked this question six month ago, but for anybody who is looking to A/B test their notifications using Firebase Cloud Messaging, this functionality is now directly built into the Firebase Notifications panel. I'd recommend checking out the documentation, and heading right into the Notifications panel of the Firebase Console to start building your A/B test.

No. Device Groups have a limit of 20 tokens per group:
The maximum number of members allowed for a notification key is 20.
High volume tokens in a group could be handled by Topics better.
