sanity check

(programming)1. Checking code (or anything else, e.g. aUsenet posting) for completely stupid mistakes. Impliesthat the check is to make sure the author was sane when it waswritten; e.g. if a piece of scientific software relied on aparticular formula and was giving unexpected results, onemight first look at the nesting of parentheses or the codingof the formula, as a "sanity check", before looking at themore complex I/O or data structure manipulation routines, muchless the algorithm itself.

Compare reality check.

2. A run-time test, either validating input or ensuring thatthe program hasn't screwed up internally (producing aninconsistent value or state).
