sanity check
sanity check n. [very common] 1. The act of checking a piece of code (or
anything else, e.g., a Usenet posting) for completely stupid mistakes.
Implies that the check is to make sure the author was sane when it was
written; e.g., if a piece of scientific software relied on a particular
formula and was giving unexpected results, one might first look at the
nesting of parentheses or the coding of the formula, as a `sanity
check', before looking at the more complex I/O or data structure
manipulation routines, much less the algorithm itself. Compare reality
check. 2. A run-time test, either validating input or ensuring that the
program hasn't screwed up internally (producing an inconsistent value or
state).

In this case you need to insure what sort of pathes the regex is
returning to you.
