I'd like ideas here... require('process'); and mock it properly?

I find it funny that eslint does not yell at me for native-reassign here

The process => properProcess dance does not prevent from modifying the global object, since Object.assign will assign to the real process. Instead you might want to save execArgv at the beginning, and re-assign to process on the afterEach.

I don't really care that I modify it, it's sandboxed for this test in particular, right?
Good idea on just messing with the part I need to mess with, though

Summary
Using
jest-workerwhen debugging caused it to crash. This ports over code from worker-farm which automatically filters away/--(debug|inspect)(-brk)?. (https://github.com/rvagg/node-worker-farm/blob/f63d988c307a6805e03b1650f8ef0fb7ca6f1546/lib/fork.js#L8-L11)Test plan
Modified test to illustrate the filtering behaviour.
