Nik is a master of this (and I learned from the CirrusSearch examples) but
such things exist in the VE repo also:
https://git.wikimedia.org/blob/mediawiki%2Fextensions%2FVisualEditor/b922592902ad57f770b6810566b820aada74aa47/modules%2Fve-mw%2Ftest%2Fbrowser%2Ffeatures%2Fsupport%2Fhooks.rb

What I did with VE was to make the tests that loop like that be runnable
both with and without the REUSE_BROWSER env variable.  When running locally
I turn on REUSE_BROWSER, but as you know, Zelkjo objects to having
REUSE_BROWSER in the production run, and I think those objections are worth
considering.

So bottom line might be to use a hook that is aware of the REUSE_BROWSER
env var.
