In an actual testing-phase, software testing manager usually observes a change of the software failure-occurrence phenomenon due to some factors being related to the software reliability growth process. Testing-time when behavior of the software failure-occurrence time interval notably changes is called change-point. Such change influences accuracy of software reliability assessment based on a software reliability growth model. This paper discusses software reliability growth modeling with the influence of the change-point by using the environmental function. Then, we check goodness-of-fit of our change-point models to actual data by comparing with the existing non-change-point models.
