OPTIMAL ALLOCATION POLICIES FOR TESTING-RESOURCE BASED ON A SOFTWARE-RELIABILITY GROWTH-MODEL

A lot of development resources are consumed during the software testin g phase fundamentally consisting of module testing, integration testin g, and system testing. Then, it is of great importance for a manager t o decide how to effectively spend testing-resources on software testin g for developing a quality and reliable software. In this paper, we co nsider two kinds of software testing-resource allocation problems to m ake the best use of the specified testing-resources during module test ing. Also, we introduce a software reliability growth model for descri bing the time-dependent behavior of detected software faults and testi ng-resource expenditures spent during the testing, which is based on a nonhomogeneous Poisson process. It is shown that the optimal allocati on of testing-resources among software modules can improve software re liability.
