In computer science
Computer science or computing science is the study of the theoretical foundations of information and computation and of practical techniques for their implementation and application in computer systems...
is the ability of a computer system to cope with errors during execution or the ability of an algorithm to continue to operate despite abnormalities in input, calculations, etc. Formal techniques, such as fuzz testing
Fuzz testing or fuzzing is a software testing technique, often automated or semi-automated, that involves providing invalid, unexpected, or random data to the inputs of a computer program. The program is then monitored for exceptions such as crashes or failing built-in code assertions...
, are essential to showing robustness since this type of testing involves invalid or unexpected inputs. Various commercial products perform robustness testing of software systems. Robustness is a consideration in failure assessment
Failure assessment, as used in the context of software systems design, is the science of determining the circumstances under which a particular algorithm fails and then correcting the cause. It is directly related to the notion of algorithm accuracy, robustness, and reliability....
