Program for derivation of characterization set given a description of corresponding finite state machine (FSM) using the W method.
Characterization set is a finite set of minimal and complete finite automaton input sequences which are guaranteed to distinguish the behavior of any pair of states in the FSM. This set can then be used as an effective test set for the FSM.
W method generates the characterization set from a sequence k-equivalent partitions. For details, see Adytia P. Marthur, "Foundations of Software Testing".
If desired, enter custom input FSM filename (in CSV format) in FSM.py and run
python2.7 FSM.py.
The output consists of state cover, edge cover, equivalence partitions, characterization set, outputs for inputs from characterization set, derived test set, and inputs from characterization set which distinguishes individual FSM states.
