(A software component is any piece of software that can be invoked as a procedure, function, or method taking one or more arguments.) In fact, several research works have been conducted in the past leading to the proposal of different robustness testing techniques for such environments. Robustness testing has also been used to describe the process of verifying the robustness (i.e. endobj << /S /GoTo /D (subsection.6.1) >> endobj (Tool Implementation and Experimental Results) endobj This technical note provides guidance and procedures for performing robustness testing as part of DoD or federal acquisition programs that have a software component.

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." Testing is a determined, systematic attempt to break a program that you think is working [KePi99]. Second, method calls with invalid inputs are fed to the component in different states to test the robustness. One approach to robustness testing, therefore, is to measure the response of a software component to invalid inputs. /Length 459 Alternatively, fault injection can be used to test robustness. Robustness can encompass many areas of computer science, such as robust programming, robust machine learning, and Robust Security Network. 72 0 obj Robustness testing is a testing methodology to detect the vulnerabilities of a component under unexpected inputs or in a stressful environment.
