Many test-cases are executed to detect and correct software errors during the testing phase in software development. Then, there is a set of modules and functions in software to be influenced by the executed test-cases. The set is called a testing-domain, which is spreading over the software. The testing-domain rate in software is closely related to the quality and the quantity of executed test-cases during testing phase. Further, the quality of test-case is related to the skill of test-case designer. In this paper, we discuss a software reliability growth model with time dependent behavior of testing-domain rate. This model is formulated by a nonhomogeneous Poisson process. Further, This model enables us to estimate and predict software reliability measures such as the initial error content of a software, the mean time between failures, the software reliability function, and so on. Finally, numerical examples are presented.
