// Note for reviewers: this intentionally duplicates functionality already in "ApiSetup" and so on.
// This framework works better IMO and has less strangeness (such as test cases inheriting from "ApiSetup"...)
// (and in the case of the other Upload tests, this flat out just actually works... )

// TODO: port the other Upload tests, and other API tests to this framework
