resolves#17645
* test: validate at least 3 capture groups were used

(https://stackoverflow.com/questions/16046620/regex-to-count-the-number-of-capturing-groups-in-a-regex)
as suggested by @RandellDawson to count the number of capturing
groups, regardless of whether or not the regex in question solves the
broader problem.
