Agree with all of that. I would say that getting everyone on board to join you on this effort and having teams open to collaboration and prioritize it high for them (because they understand the importance) is key to making this work.

Like with everything else you can’t really “force” developers/teams to write tests and you will always get the same rejections about investing time in it etc. This applies here as well.

As for maintenance, I don’t think there’s really any overhead for the broker or anything else, just every team needs to own their part (consumer/provider tests).

I will probably share it by the end of the month, possibly the beginning of February. Stay tuned! I’d be happy to get a lot of feedback about it.
