A software testing-management tool (SAFEMAN) and its application

摘要

Generally, in the case of a large-scale software development, more than the half of the total development effort is said to be spent on the testing phase. Therefore, the management of the fault-detection and fault-correction activities in the testing phase is very important to efficiently and economically develop a highly-reliable software product. In this paper, a software testing-management tool which can support the quality/reliability assessment and testing-progress control in the testing phase is developed. Five software reliability growth models (SRGM's), i.e. exponential SRGM, delayed S-shaped SRGM, testing-domain dependent SRGM, testing-domain dependent SRGM with skill-factor which are based on a nonhomogeneous Poisson process, and the Compertz curve model which is a deterministic regression model, are built into the this tool. We implement this tool by using a C++ language. This language is widely known as an object-oriented language. Finally, application examples of this tool to the fault data observed in an actual development project are shown.
