Structure‑Aware Fuzzing Experiment Reveals Generation vs. Mutation Trade‑offs for Wasm
Nick Fitzgerald built both generation‑based and mutation‑based structure‑aware fuzzers for WebAssembly, using Wasmtime as the target and libfuzzer‑sys as the engine. By comparing code‑coverage over time, the experiment shows how each approach affects testing depth and offers practical guidance for developers adopting structure‑aware fuzzing.
