I have to respond here as I seemingly the depth limit is reached.
As you've mentioned graphql you probably comparing ORM in that sense to an traditional custom API with backed by raw sql. In a fair comparison both version would do the exactly same, require the same essential tests. Assuming more variations for the raw sql version is just assuming it does more or somehow does it badly in terms of architecture. Which is not a fair comparison.
