How do you make shared App set-up code for Tests?


I've some shared code between tests namely
Setting up `actix_web::App::new` which returns `actix_web::app:App<actix_web::app_service::AppEntry>`
I can't make a common setup function because I can't return `actix_web::app_service::AppEntry` because `actix_web::app_service` is private but `AppEntry` is public.
