We've tried using external/public API endpoints in the tests, but intermittent connection failures (network delays) broke the CI. I believe a stronger testing framework for URLSession will be provide support in making the implementation robust. 

How hard it would be to fake enough of a web server to test URLSession against? Maybe involving the Swift Server APIs, once those are ready? They might even have the functionality to fake network issues for their own testing, which we should be testing against anyway to ensure that things fail correctly.
