Enhanced testing for compliance with universal plug and play protocols

The present invention extends to methods, systems, and computer program products for enhanced Universal Plug and Play ("UPnP(TM)") compliance testing. A control point (e.g., a computer system) and one or more devices (e.g., printers, wireless gateways, etc.) are network connectable (or are connected) to a common network. The control point includes a test tool that can execute scripts to simulate UPnP(TM) functionality. Using scripts allows more flexible and programmatic UPnP(TM) compliance testing. Multiple devices can be selected for testing thereby reducing the burden associated with individually testing devices on an isolated network. Test logs can be secured using digital signatures to reduce the likelihood of test logs being intentionally or inadvertently altered prior to being received at a certification authority.
