state transition tool for test generation

[winsvega]

Suggestion:

Each client that want to be able to generate the tests or debug certain state transition implements a state-transition tool as an alternative to test-rpc methods.
The state-transition tool takes input like this (to be discussed):

}

and produces an output like this (to be discussed):
