Use simple match in test (to avoid warning about expensive regex)

[shadowspawn]

Problem

CodeQL reports:

Polynomial regular expression used on uncontrolled data

for regex assert(!/\W-h\W.*display help/.test(helpInformation));

Solution

This isn't a vulnerability since only used within test with controlled data, but want to fix warning/error anyway.

Just replace regex with some simple string matches.
