Robustness is the property of being strong and healthy in constitution. When it is transposed into a system, it refers to the ability of tolerating perturbations that might affect the system’s functional body.
1a : having or exhibiting strength or vigorous health. b : having or showing vigor, strength, or firmness a robust debate a robust faith. c : strongly formed or constructed : sturdy a robust plastic. d : capable of performing without failure under a wide range of conditions robust software.
n computer science, robustness is the ability of a computer system to cope with errors during execution and cope with erroneous input. Robustness can encompass many areas of computer science, such as robust programming, robust machine learning, and Robust Security Network. Formal techniques, such as fuzz testing, are essential to showing robustness since this type of testing involves invalid or unexpected inputs. Alternatively, fault injection can be used to test robustness. Various commercial products perform robustness testing of software analysis
Robustness testing is any quality assurance methodology focused on testing the robustness of software. ... ANSI and IEEE have defined robustness as the degree to which a system or component can function correctly in the presence of invalid inputs or stressful environmental conditions.
