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

[codecnotsupported]

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.
