Evaluation of software testing process based on Bayesian networks

In this paper, we will introduce a Bayesian networks (BN) approach for probability evaluation method of software quality assurance. Then, we will present a method for transforming Fault Tree Analysis (FTA) to Bayesian networks and build an evaluation model based on Bayesian networks. Bayesian networks can perform forward risk prediction and backward diagnosis analysis by deduction on the model. Finally, we will illustrate the rationality and validity of the Bayesian networks through an example of evaluation of software testing process.
