I recently ran into a V8 test failure that only showed up in the V8 fork of Node.js but not in the upstream. Here I’ll write down my workflow used to debug the failure in case anyone (or myself) need to do this again and don’t know where to start.
I thought about writing some guides on this topic in the nodejs/node repo, but it’s easier to throw whatever tricks I personally use on the Internet first - I am also going to heavily use the pronouns “I”, “We” and “You” in this post, and talk about my personal preference here, both of which we always try to avoid in the repo ;)
