Within the software industry, the pace of software upgrades remains swift due to fierce market competition and rapidly evolving requirements. The fluctuating composition of development teams poses challenges in testing upgraded software. Despite this, limited attention has been devoted to testing strategies and reliability estimation for upgraded software systems, leveraging past testing data. Therefore, it is important and necessary to develop an effective testing strategy in order to ensure the product quality. In this paper, an upgradation software testing strategy adapted to requirements change will be proposed combined with the software development process of Parking Lot Mobile Payment System (PLMPS). In this approach, the testing information of the pre-versions and software functional structure will be fully used in upgradation software testing. Moreover, an upgradation software reliability model can be constructed based on proposed testing strategy. The proposed reliability model also can be applied to multi upgradation software systems. Furthermore, the proposed approach can help managers and developers generate testing cases and predict software reliability. A numerical example based on simulation data is given to illustrate its application in the modeling process.
