This repo contains preset scripts for fuzzing of Rust implementation, fuzzing gas estimator (those are not too interesting), and differential testing between C++ implementation and Rust implementation. All scripts are Rust files, so C++ is wrapper into the thin layer.
Requires:
- C++17 compiler
- Nightly Rust
- Install using manual
Usage:
cd fuzzbash run_fuzz_compare.sh
Requires:
- C++17 compiler
- Stable Rust
- Install using manual
Usage:
cd honggfuzzbash run_honggfuzz_compare.sh
- Change number of threads for fuzzers in scripts
- Download initial corpus from here and follow the instructions of either here or here
- Honggfuzz is recommended for speed
- Now Honggfuzz saves all results instead of unique ones. Due to differential testing being implemented as "panic on different results" fuzzer considered different reasons as one crash case.

Folder cross-tester contains few examples how to specify inputs from fuzzer reports debug and compare implementations.
