However the suite definition describes the static structure, it its not until it the definition is loaded in the server, that we see its dynamic behaviour.
The python api allows the simulation of the dynamic behaviour of the suite, ( i.e. in the same manner as the server).

This python segment show shows how to load a text based suite definition(cron.def) and simulate it in python.
...
Both files will show which nodes are holding, and include the state of the holding trigger expressions.
def simulate_deadlock():
This simulation is expected to fail, since we have a deadlock/ race condition
