Test Fuzz

test-fuzz accomplishes these (in part) using Rust's testing facilities. For example, to generate a fuzzing corpus, test-fuzz records a target's arguments each time it is called during an invocation of cargo test. Similarly, test-fuzz implements a fuzzing harness as an additional test in a cargo-test-generated binary. This tight integration with Rust's testing facilities is what motivates the name test-fuzz.
