What Hacker News says
3 sourcesAgreed. A while back I played around with fuzzcheck [1], which let's you write coverage-guided, structure-aware property tests, but the generation is smarter than just slamming a fuzzer's `&[u8]` input into `Arbitrary`. It also supports shrinking, which is nice. Don't know that I would recommend it though. It seemed difficult to write your own `Mutator`s. It also looks somewhat unmaintained nowadays, but I think the direction is worth exploring.
