Bifurcum

This software runs through a directional graph and writes the paths it found as test specifications.
It has a simple algorithm (Deep First Search with modifications) and allows sorting children before traversing.
This application sums up the authors 4-years experience when programming a commercial tool for graph traversing (which used a much more advanced algorithm) and coaching its users.
Technically it is a front end for the library Bifurcumlib.
