Xception [27] is a commercial software tool developed by Critical Software SA [28] used for black box and white box testing based on software fault injection (SWIFI) and Scan Chain fault injection (SCIFI). Xception allows users to test the robustness of their systems or just part of them, allowing both Software fault injection and Hardware ...
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]
[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.

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.
Hoglund contributed early research to the field of rootkits, software exploitation, buffer overflows, and online game hacking. His later work focused on computer forensics, physical memory forensics, malware detection, and attribution of hackers. He holds a patent on fault injection methods for software testing, and fuzzy hashing for computer ...

The software being tested is "mission critical", that is, failure of the software (such as a crash) would have disastrous consequences. The amount of time and resources dedicated to testing is usually not sufficient, with traditional testing methods, to test all of the situations in which the software will be used when it is released.
