As an additional note, the test suite ideally needs to be able to
exercise failure modes where the provider itself is malfunctioning. So
we hand-roll responses rather than deferring to an external
OAuth/OpenID implementation, which adds HTTP and JSON dependencies at
minimum, and Python includes both. See also the discussion with
Stephen upthread [1].

(I do think it'd be nice to eventually include a prepackaged OAuth
server in the test suite, to stack coverage for the happy path and
further test interoperability.)
