There was a problem hiding this comment.
Nit (more of an FYI than a blocker): I really dislike the pattern of hiding test data in the setup methods, but since this is the existing convention, we should probably wait to clean that up in a separate PR.
tests should never rely on default values that are specified by a helper method
