some code like

field :paged_posts, :paged_posts do
    arg(:filter, non_null(:paged_article_filter))
    
    middleware(M.PageSizeProof)
    resolve(&Resolvers.CMS.paged_posts/3)
    middleware(M.FormatPagination)
end

some file like page_post_test

has lots of boilerplate code with job, video, repo ... should use macro to reduce it
