Thank you 
I know this is controversial but we are doing real HTTP in the tests, as there are multiple layers and ways to mock each of them, at some point we decided it was simpler to test the real thing. This is for a custom HTTP client so it must do HTTP properly and this allows to not depend on a particular library such as Req.
That being said I doubt we will move from req anytime soon and our mock_http_server is also an abstraction that could leverage the test features of Req, but this has to be setup properly. It’s on my list though.
Today I just need a quick fix.
edit for @Eiji
I found a lot of people who cleary reject the idea of performing an actual http call during the tests, more so if you also start the test http server from the test (which we do, we never actually call a 3rd party server), especially when alternative solutions are possible like with Req. This is what I mean by controversial, I don’t personally think it’s bad.
