XCM Simulator Fuzzer
This project will fuzz-test the XCM simulator. It can catch reachable panics, timeouts as well as integer overflows and underflows.
Install dependencies
cargo install honggfuzz
Run the fuzzer
In this directory, run this command:
cargo hfuzz run xcm-fuzzer
Run a single input
In this directory, run this command:
cargo hfuzz run-debug xcm-fuzzer hfuzz_workspace/xcm-fuzzer/fuzzer_input_file
Generate coverage
In this directory, run these four commands:
RUSTFLAGS="-Zprofile -Ccodegen-units=1 -Copt-level=0 -Clink-dead-code -Coverflow-checks=off -Zpanic_abort_tests -Cpanic=abort" CARGO_INCREMENTAL=0 SKIP_WASM_BUILD=1 CARGO_HOME=./cargo cargo build

zip -0 ccov.zip `find ../../../target/ \( -name "*.gc*" -o -name "test-*.gc*" \) -print`
grcov ccov.zip -s ../../../ -t html --llvm --branch --ignore-not-existing -o ./coverage
The code coverage will be in ./coverage/index.html.
