  Google released in 2013 a script-based tool called packetdrill, which allows
to test transport protocols like UDP and TCP on Linux and BSD-based operating
systems. The scripts defining a test-case allow to inject packets to the
implementation under test, perform operations at the API controlling the
transport protocol and verify the sending of packets, all at specified times.
This paper describes a port of packetdrill to the INET framework for the
OMNeT++ simulation environment providing a simple and powerful method of
testing the transport protocols implemented in INET.
