Sorry, maybe I wasn’t clear, I was wondering if there’s a test suite that regularly runs against _both_ the open-source Foundation implementation _and_ the closed-source Foundation implementation in order to catch inconsistencies across code bases.

I don’t have a strong enough opinion to argue for or against auto-capitalizing the HTTP method, but I _do_ care for consistency across platforms. We have a significant test suite in our code bases with a lot of unit tests and snapshot tests that pass on our dev machines (Mac), but fail on Linux.
