Implement a server using tested software locally and connect to it. Even better find server software that does very detailed logging.

Out here we use wireshark traces for lab testing of POC ( proof of concepts ) applications . Just in case if that helps your case

ps: for deployed apps running at client environments use Network Test Factory , TCS offering .
