Sanity Test

Sanity Test
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 produce materiel 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 may be check to perform the test.

Advantage of Sanity Test


In Arithmetic
Sanity Test over performing a complete or rigorous test, is speed. In arithmetic, for example, when multiplying by 9, using 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 but it's quick and simple method to discover many possible errors.

In Science
The sanity test is very brief run-through of the functionality of a computer program, system, calculation, or other analysis, to ensure that part of the system or methodology work roughly as expected.
