I do, and people do seem to use it for testing (hilariously not a use case I’d initially considered when writing it), but I’m pretty lax about maintaining it. The dependencies I (today) noticed are quite out of date and non-trivial to update. If you’d like to check it out, it’s here: https://crates.io/crates/regex_generate/0.2.3
If you’d like a more updated version, there are a few forks but also someone seems to have taken the concept and run a little farther with it: https://crates.io/crates/rand_regex
That one seems more explicitly for testing and might be suitable to your needs. These are both Rust crates but should be usable from any language with a C compatible FFI.
