(setq testprocess
      (make-network-process :name "test"
                            :host 'local
                            :server t
                            :service t
                            :family 'ipv4))

This works fine on emacs 24. It is not working in emacs 25. In emacs 25, it seems that only string and integer is accepted.

:service service

    service specifies a port number to connect to; or, for a server, the port number to listen on. It should be a service name that translates to a port number, or an integer specifying the port number directly. For a server, it can also be t, which means to let the system select an unused port number.
