Wikipedia
Sanity check
A sanity check or sanity test is a basic test to quickly evaluate whether a claim or the result of a calculation can possibly be true. It is a simple check to see if the produced material is rational (that the material's creator was thinking rationally, applying sanity). The point of a sanity test is to rule out certain classes of obviously false results, not to catch every possible error. A rule-of-thumb or back-of-the-envelope calculation may be checked to perform the test. The advantage of performing an initial sanity test is that of speedily evaluating basic function. In arithmetic, for example, when multiplying by 9, using the divisibility rule for 9 to verify that the sum of digits of the result is divisible by 9 is a sanity test—it will not catch every multiplication error, however it's a quick and simple method to discover many possible errors. In computer science, a sanity test is a very brief run-through of the functionality of a computer program, system, calculation, or other analysis, to assure that part of the system or methodology works roughly as expected. This is often prior to a more exhaustive round of testing.

sanity check
A sanity check is a basic, informal evaluation or test performed to verify that something is logical, rational, or reasonable. It is essentially a quick assessment to ensure that a particular result, decision, or action makes sense and is in line with expectations or common sense. A sanity check helps to identify obvious errors, inconsistencies, or outliers before proceeding with more detailed or rigorous analysis.
The New Hacker's Dictionary
sanity check
[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). 3. Conversationally, saying “sanity check” means you are requesting a check of your assumptions. “Wait a minute, sanity check, are we talking about the same Kevin here?”
