Fuzz Testing

Rustls supports fuzz testing using cargo-fuzz. Fuzz tests are automatically run during continuous integration using oss-fuzz. You may also run fuzz tests locally. See the cargo-fuzz setup instructions for requirements.

bash

# List available fuzzing targets.
$ cargo fuzz list

$ cargo fuzz run message -- -max_total_time=120

git clean --interactive -- ./corpus
