Research on the Nonintrusive Resource Level Fault Injection Technology for Windows System

摘要

There are often a few harsh testing scenarios need to simulate, such as the bandwidth of the network is limited, the memory is overload or the file system access is denied. Now, there have been some traditional methods to simulate those faults, but these methods often make damage on the system resource or the code of the system under testing. Using the interception service of Windows system, the nonintrusive resource level fault injection methods are proposed to simulate resource level faults accurately. Then a fault injection tool named JariFI is designed, which can inject faults needed in software testing and reliability evaluation. At last, the accuracy and the function applicability about the tool are verified by the fault injection experiment.
