Bayesian Testing Strategies for Software with an Operational Profile
We consider a software reliability model where the failure rate of each fault depends on the specific operation performed. The software is tested in a given sequence of test cases for fixed durations of time to collect data on failure times. We present a Bayesian analysis of software failure data by treating the initial number of faults as a random variable. Our analysis relies on the Markov Ch...
متن کاملResearch on software reliability considering testing profile and operational profile
The testing and operation environments may be essentially different, thus the predicted reliability of the testing phase is different from that of the operational phase. On the basis of analyzing similarities and differences of the testing phase and the operational phase, using the operational reliability and the testing reliability, different forms of the comparison between the operational fai...
متن کاملStochastics and Statistics Reliability of software with an operational profile
This article provides the stochastic and statistical framework to model software reliability in the presence of an operational profile. The software system is used under a randomly changing operational process so that the failure characteristics depend on the specific operation performed. The operational process describes, in a probabilistic sense, how the software is utilized by the users. The...
متن کاملSoftware Testing with Evolutionary Strategies
This paper applies the Evolutionary Strategy (ES) metaheuristic to the automatic test data generation problem. The problem consists in creating automatically a set of input data to test a program. This is a required step in software development and a time consuming task in all software companies. We describe our proposal and study the influence of some parameters of the algorithm in the results...
متن کاملPosition Paper: Bayesian Reasoning for Software Testing
Despite significant advances in software testing research, the ability to produce reliable software products for a variety of critical applications remains an open problem. The key challenge has been the fact that each program or software product is unique, and existing methods are predominantly not capable of adapting to the observations made during program analysis. This paper makes the follo...
