test/common/index.js

Is block scoping really needed?

Since the const are only used locally and there's a single exported side-effect (exports.PIPE = ...) IMHO it's cleaner.
Similar to the function setupFoo(); setupFoo(); approach in node_bootstap.js
Maybe even V8 will inline the consts ?

I like it, easier to see that the consts aren't used except in exports.PIPE.

test/common/index.js

Not a huge fan of !! outside of minimal code competitions.
Willing to change if anyone has a strong opinion.

No strong opinion from me. I think it used to be preferred in hot paths for performance. No idea if that's still the case. Regardless, it's totally sensible to value readable code over performant code in test/common/index.js.
