Hi friends, I'm looking for tooling recommendations for doing property testing and fuzz testing in: Ruby, JavaScript/TypeScript, Go, Rust.

In Python, I'd use Hypothesis and Atheris but what are the good tools in those other languages?

I know that AFL++ can be used with targets written in any language, and that's great, but I'm also interested in language-specific tooling, if/where it exists.

Especially interested in personal success — I can Google too but want to know what worked for you.

@jacob I’ve been using Rapid on the Go side recently, and been happy with it https://pkg.go.dev/pgregory.net/rapid

@jacob oh, I wrote something which might be helpful for you not too long ago (Rust): https://blog.yoshuawuyts.com/bridging-fuzzing-and-property-testing/

Of anything, it should provide enough jumping off points to decide what is the best fit for your own work.

@yosh thanks! (and it's very cool to see that I'm not the only one who sees a through-line connecting property and fuzz testing)

@jacob for JS, the only thing that was remotely workable and maintained as of last December was jazzer.js which er helped integrate with a project.
