Ok, agree. Those tests are now pretty poor.

Agree. I was thinking about not just one test per service but rather several tests that comprise a representative subset of certain service functionality.

Yeah, I wonder if we can use openstackclient instead of individual clients. Do think it’s possible? The bad thing about the current approach is that we should rely on different clients whereas not all of them are built in the same way. So we have to come up with certain tricks and it’s very volatile and hard to maintain.
> Also, I think we should get rid of mapping.json file (Don't know right now how) because its size will increase as we support more actions and it will become difficult to maintain this file.
Ideally, yes, but the issue I see here is that actions must be registered in DB, this is how the whole model works. So we’ll have to migrate DB every time we detect some changes.
Regarding this, we discussed the idea of action providers long ago, . It’s basically about moving away from having to store action definitions in DB. Instead we could register a number of providers and each of them could provide an interface to work with actions: get action, get list of them, etc. Maybe we need to resurrect this BP again when rebuilding action mechanism.
Just one more note: keep in mind that we’re now revisiting all the approach around actions and a number of activities are going on, e.g. . Eventually, these actions and tests for them will go into a different repository.
