        people {
            name
        }
    }
}

valid

mutation UpdatePeople {
    updatePeople(update: { movies: { create: { node: { title: "The Good" } } } }) {

            name
        }
    }
}

This looks good! I won't comment on every one, but any reason you opted to remove some of these tests instead of updating them?

[angrykoala]

Lots of those are redundant, either because we had duplicate tests, or because now that we have a single path, the other was already tested.
