unit testing - Comprehensive test-case(s) for finding all cycles in a directed graph? -


i've implemented algorithm finding cycles in directed graph. think it's correct, won't leave intuition. i've written number of simple tests, i'm not sure handled edge cases (or vertex cases... hehe, i'll here week).

anyway, i'm sure i'm not first 1 doing this. can point me existing test-suite, i.e., comprehensive set of directed graphs plus list of cycles?
