The intuitive notion exists in industry and among regulators that successful use of a commercially available software-based component over some years and within different application environments must imply some affirmative statement about the quality of the component and - in terms of a safety-case - that it should provide evidence to support a specific safety claim for usage of the component in...
There is growing interest in statistical software testing (SST) as a software assurance technique. While the approach has major attractions, there is a need for new statistical models to infer failure probabilities from SST. The paper constructs a simple but realistic case in which the traditional binomial model does not work. The paper shows that if possible test failure dependencies are neglected,...
Statistical testing can produce dependability information by estimating the probability of failure on demand for a system. In this paper we explore issues related to the construction of statistical test-cases for the firmware of a smart device. Our aim is to share our own experience with the technique and we expect to derive some general insights into what needs to be taken into account when designing...
Statistical testing (ST) of software or logic-based components can produce dependability information on such components by yielding an estimate for their probability of failure on demand. An example of software-based components that are increasingly used within safety-related systems e.g. in the nuclear industry, are smart devices. Smart devices are devices with intelligence, capable of more than...
