摘要：In this case study, the methodology of test case preparation proposed in the first article is applied to the design of a testing plan in order to verify the compliance of the functional requirements for the compiling system of an F23 tax payment form. The objective of this approach is the definition of the functional requirements coverage matrix to associate one specific test case with each system component. This methodology's aim is to equip the software designers with an accurate testing plan that is perfectly aligned with the designing logics of the system, respectively in order to optimize the time used for software implementation, to ensure that the tax deadlines are met, and to satisfy the user requirements. This approach also allows to manage a test plan configuration for the software's future versions, while having, at the same time, an updated technical documentation always available. In fact, with the application of the reuse technique we can identify the software objects affected by the technical and regulatory annual updates. Specific test cases are designed for them, whereas the unmodified components will keep the test cases used in their previous version.
