Run Fuzz Target
Run fuzz tests against the scanner's parsing and decoding logic.
Usage
run-fuzz <target>- Run specific fuzz target (default 10,000 runs)run-fuzz <target> <runs>- Run with custom iteration countrun-fuzz all- Run all targets briefly (1,000 runs each)run-fuzz list- List available targets
Available Targets
| Target | Tests |
|---|---|
fuzz_anchor_soundness |
Anchor extraction correctness |
fuzz_b64_gate_build_and_scan |
Base64 gate construction and scanning |
fuzz_b64_gate_determinism |
Base64 gate deterministic behavior |
fuzz_b64_gate_differential |
Base64 gate differential testing |
fuzz_tiger_chunking |
Tiger harness chunking logic |
Workflow
Run Single Target
cd fuzz && cargo +nightly fuzz run <target> -- -runs=10000
Run All Targets
cd fuzz
for target in fuzz_anchor_soundness fuzz_b64_gate_build_and_scan fuzz_b64_gate_determinism fuzz_b64_gate_differential fuzz_tiger_chunking; do
echo "Running $target..."
cargo +nightly fuzz run $target -- -runs=1000
done
Check for Crashes
Crashes are saved to fuzz/artifacts/<target>/. To reproduce:
cargo +nightly fuzz run <target> fuzz/artifacts/<target>/<crash-file>
Prerequisites
- Nightly Rust toolchain:
rustup install nightly - cargo-fuzz:
cargo install cargo-fuzz
