Software reliability assessment tool for the system testing phase in distributed development environment

At present, software development environment has been changing into new development paradigm by using network computing technologies. In this paper, we propose a software reliability assessment tool incorporating flexible software reliability growth models (abbreviated as SRGM's) based on nonhomogeneous Poisson process (abbreviated as NHPP) and stochastic differential equations (abbreviated as SDE) for distributed debelopment environment by using Java programing language and J/Link technology in Mathematica(1). Especially, we apply the graphics facility by using U-plot for performing the goodness-of-fit testing to our tool. A Java is an object-oriented and platform -free programming language which has several advantages such as modularization and reuse of the existing code. Especially, the J/Link can use and control the Mathematica kernel from a Java program. By using this J/Link technology, we can reduce some efforts to develop the tool because of reusing the existing Mathematica code used for our research. Our tool proposed here is useful for software developers in terms of the management of the testing process in distributed development environment.
