Upstream plans to run the tests completely on pytest-httpbin, which provides a locally running instance of httpbin [1]. There are already some steps towards this in the pytest-httpbin branch [2].
I'm working on pytest-httpbin [3] and httpbin [4] to make them available. When they are becoming, either upstream made this feature available or maybe some patch work would be necessary. I'm on it.
