MT - 40 - Exhaustive testing - Is it possible in real ?

Exhaustive testing is an approach in which all the possible inputs are tested against a system. It covers all the data combinations to test a system.In this type of testing we try to check the output given by the software by entering all the possible inputs, in fact we use all the permutations and combinations of the inputs. Each element of code is verified under this process. This way we are able to find software endurance as well as its ability to handle extreme situations. Exhaustive testing is the process of testing for absolutely everything just to make sure that the product cannot be destroyed or crashed by some random inputs. It takes into consideration all possible combinations of inputs, usage scenarios as well as random situations and inputs.

Is it possible ?
So here I'd like to say that it totally depends on the type and size of application. If our application is very small then the ans will be yes but for very large system its impossible.Although it provides complete surity of correctness of application but its rarely done in real practice.
