|Title:||Experimental Risk Assessment And Comparison Using Software Fault Injection|
|Abstract:||One important question in component-based software development is how to estimate the risk of using COTS components, as the components may have hidden faults and no source code available. This question is particularly relevant in scenarios where it is necessary to choose the most reliable COTS when several alternative components of equivalent functionality are available. This paper proposes a practical approach to assess the risk of using a given software component (COTS or non-COTS). Although we focus on comparing components, the methodology can be useful to assess the risk in individual modules. The proposed approach uses the injection of realistic software faults to assess the impact of possible component failures and uses software complexity metrics to estimate the probability of residual defects in software components. The proposed approach is demonstrated and evaluated in a comparison scenario using two real off-the-shelf components (the RTEMS and the RTLinux real-time operating system) in a realistic application of a satellite data handling application used by the European Space Agency. © 2007 IEEE.|
