-- | Tests for object remote relationships to databases. Remote relationships
-- are relationships that are not local to a given source or remote schema, and
-- are handled by the engine itself. Object relationsips are 1-to-1
-- relationships.
--
-- All tests use the same GraphQL syntax, and the only difference is in the
-- setup: we do a cartesian product of all kinds of sources we support on the
-- left-hand side and all databases we support on the right-hand side.
