The Twins demo is an example of asynchronous peer-to-peer communication between 2 identical, threaded component instances, refer to context diagram below. Each peer can send a question to the other peer via its output port, receive a question via its input port, send an answer via its output port, and receive an answer via its input port. This illustrates a communication protocol involving 2 ports for each peer. The implementation has an orthogonal state machine with 2 regions: for the question and for the answer. This enables full duplex communication behaviour.
Verification happens not at the port level but at a higher 'application' level. The context architecture TwinsTest can be verified without the need for component instances having stereotype Mock. The NativeTriggers are the driving forces for stimuli.
Furthermore, this demo also includes an application where the peers send 10 questions/answers to eachother. The context diagram of this application is shown here:

TismTool reports the following remarks about the UML model:
W 4535: Self-transition is errorprone for NativeTrigger @ ( Xmi > Data > Protocols > TwinProtocol > TwinServer > TwinServerPsm >> Idle )
W 4535: Self-transition is errorprone for NativeTrigger @ ( Xmi > Data > Protocols > TwinProtocol > TwinServer > TwinServerPsm >> Idle )
ad W 4535:
Self-transitions may cause an unlimited number of messages to a receiver causing queue overflow.
