Robustness testing [5] (also known as syntax testing, fuzzing or fuzz testing) is a type of fault injection commonly used to test for vulnerabilities in communication interfaces such as protocols, command line parameters, or APIs. The propagation of a fault through to an observable failure follows a well-defined cycle.
These techniques worked by adding a number of known faults to a software system for the purpose of monitoring the rate of detection and removal. This assumed that it is possible to estimate the number of remaining faults in a software system still to be detected by a particular test methodology. Bebugging is a type of fault injection.
[citation needed] Software fault injection, in the form of fuzzing, is an example of failure testing. Various commercial non-functional testing tools are linked from the software fault injection page; there are also numerous open-source and free software tools available that perform destructive testing.
Nondestructive testing: analysis techniques to evaluate the properties of a material, component or system without causing damage. Fault injection: A testing technique which stress the system in an unusual way to examine the system behavior. [2] [3] [4]
Fault injection is a testing method that can be used for checking the robustness of systems. During the process, testing engineers inject faults into systems and observe the system's resiliency. [4] Test engineers can develop efficient methods which aid fault injection to find critical faults in the system. [5] [6]
Practical fault injection consists of using an electromagnetic probe connected to a pulser or a laser generating a disturbance of a similar length to the processor's cycle time (of the order of a nanosecond). The energy transferred to the chip may be sufficient to burn out certain components of the chip, so the voltage of the pulser (a few ...
To test OBD-II scanners, we pulled a 2005 Toyota Corolla into the Car and Driver garage. We then set to work manufacturing a check-engine light (CEL) by unplugging the mass-air-flow sensor.
