An unconventional software testing method, fault injection based on fault model, is enhanced to improve the software reliability testing and measurements. Dynamic fault models for injecting faults through software are investigated and reported in this paper including memory faults, CPU faults and communication fault models. Dynamic fault models can be used to simulate influences which are caused by...
Fault injection is an effective method for PHM and testability validation. However, with the increasing complexity of structures and functions, and with the promotion of integration levels for airborne prognostics and health management (PHM) and integrated modular avionics (IMA) systems, fault injection is often difficult to use in conventional “plug,” “probe,” or “adaptor plate” methods. Fault injection...
The phenomenon of high availability (HA) is of vital importance in cloud architecture. This paper proposes an HA verification framework, called HAVerifier, for OpenStack, a popular open source cloud platform. Fault injection technology has been adopted to verify the system's reliability by determining its health status after injecting faults. The framework proposed in this paper verifies the availability...
