assert_matches_sample doesn't care about the request #10

I have some json files defining a series of requests.
I use them for tests, but would also like to give them to others to use as examples of how to use my API.

As a result, I'd like to make sure when I change something internally that I keep my docs up to date.

Currently assert_matches_sample AFAICT only cares about the response matching, not about eg:

• Method used (GET/POST...)
• Body of request.
