One of the most important points to improve the robustness of our software is to test it. (UTP as root of semantic theory) Conformance testing checks the consistency between the behavior and component specifications. First, a set of paths is generated to cover transitions of the state machine, and it is used by the test cases to bring the component into a specific control state. Experimental details of the testing procedures are provided in Appendix B of EPC’s Phase 11 Reliability Report. But they do not take into account component states, which are vital to the detecting robustness problem of a component. 73 0 obj We use cookies to help provide and enhance our service and tailor content and ads. 16 0 obj 57 0 obj (Discussion) On the other hand, robustness testing detects vulnerability of software with unexpected input or stressful environment. endobj 44 0 obj << /S /GoTo /D (subsection.6.1) >> Firstly, a set of paths is generated to cover transitions of the state machine, and it is used by the test cases to bring the component into a speci c control state. endobj In today’s modern electrical environments it is becoming more and more likely that the complexity of systems that include electronic controllers will experience functionality issues when the supply voltage is not as intended. endobj This technical note provides guidelines for performing robustness testing as part of Department of Defense (DoD) or federal acquisition programs that have a software component. 77 0 obj endobj Testing is a determined, systematic attempt to break a program that you think is working [KePi99]. << /S /GoTo /D (subsection.4.1) >> On the other hand, robustness testing detects vulnerability of software with unexpected input or stressful environment.
