Existing tests: block, transaction, signature, cold outputs, cold transaction. Data for these is in tests/data/fuzz. A convenience shell script is in contrib/fuzz_testing/fuzz.sh, eg: contrib/fuzz_testing/fuzz.sh signature The fuzzer will run indefinitely, ^C to stop. Fuzzing is currently supported for GCC only. I can't get CLANG to build Monero here as it dies on some system headers, so if someone wants to make it work on both, that'd be great. In particular, the __AFL_LOOP construct should be made to work so that a given run can fuzz multiple inputs, as the C++ load time is substantial.
