Hi all,

I currently have a chrome service that is parsing some potentially malicious HTTP requests in an separate process and I would like to now fuzz that functionality. Is there some particular fuzzing framework that we generally use in chromium?

I found https://chromium.googlesource.com/chromium/src/+/master/testing/libfuzzer/efficient_fuzzer.md, is this still current or is there a new workflow that I should be following instead?

Thanks!
Luum

Yes, I believe libfuzzer is still the thing to use. https://chromium.googlesource.com/chromium/src/+/master/testing/libfuzzer/getting_started.md is the main doc about it, the one you linked is a followup.

https://chromium.googlesource.com/chromium/src/+/master/testing/libfuzzer/getting_started.md is our doc on fuzzing using libfuzzer (generally the preferred method) in Chrome.
There are some links to our other fuzzing docs here.
