Have collections of requests

[merveenoyan]

It would be nice to have something like postman collection of requests somewhere (doesn't necessarily have to be a postman collection), where there's requests, expected bodies, and outputs collected in a tidy way. @Narsil @OlivierDehaene
For context, I want to see where warnings are put to fix this issue. Thought it would be nice to have in general.

Or the OpenAPI spec.

Since community don't have too many parameters and have regular output types it could be the easiers (the transformers API was a nightmare to maintain exhaustively because we have many parameters, and unfortunately as many return types most of the cases, with all sorts of weird behaviors that we cannot break in transformers.
