Robustness has been defined by the Food and Drug Administration as "the degree to which a software system or component can function correctly in the presence of invalid inputs or stressful environmental conditions." Formal techniques, such as fuzz testing, are essential to showing robustness since this type of testing involves invalid or unexpected inputs.
