graphene_client does not return expected data queried with an order_by

I am using pytest-django graphene-django and the first test went well, but one I add a query with an order by. I always get ascending records while I want the opposite. Moreover, in GraphQL view everything works fine when I query with an order_by.

I think that data should be returned as JSON instead of dictionaries from `graphene_client.execute()`.

Start by reproducing the order_by case through graphene_client.execute() and compare its result with the GraphQL view, as described in the issue. Trace how the client result is represented and verify that descending ordering is preserved; done means the client returns the expected ordered data and the regression is covered by a test.
