Sets up and runs Ruzzy, Trail of Bits' coverage-guided Ruby fuzzer and the only production-ready one for the language. Covers harness structure, fuzzing pure Ruby and the native C extensions in gems, and sanitizer builds. Use when fuzzing a Ruby library or gem, testing a Ruby C extension for memory safety, or asking how to fuzz Ruby at all.

When to use

Fuzzing Ruby applications or libraries
Testing Ruby C extensions for memory safety issues
You need coverage-guided fuzzing for Ruby code
Working with Ruby gems that have native extensions

When not to use

Fuzzing non-Ruby languages
macOS or Windows native execution without Docker
