parity-wasm
supports full wabt testsuite (https://github.com/WebAssembly/testsuite), running asserts that invloves deserialization.
To run testsuite:
wabt
(since parity-wasm builds it internally using wabt-rs
, see https://github.com/WebAssembly/wabt)git submodule update --init --recursive
)cargo test --release --manifest-path=spec/Cargo.toml
Decoder can be fuzzed with cargo-fuzz
using wasm-opt
(https://github.com/WebAssembly/binaryen):
binaryen
and cargo-fuzz
(cmake
and a C++11 toolchain)git submodule update --init --recursive
)cargo fuzz
subcommand with cargo install cargo-fuzz
cargo fuzz
uses a rust compiler plugin: rustup override set nightly
cargo fuzz run deserialize
