Development of a prototype tool to automate the counting of SNAP function points of the graphical interface

In this work we present the results of the creation and evaluation of a tool prototype that automatically calculates the size of the non-functional requirements (NFR) of the User Interface 2.1 subcategory of the SNAP (Software Non-functional Requirements) method. Assessment Process). We evaluated the accuracy of the tool compared to manual counting and results show an accuracy level of 100% in SNAP point counting for category 2.1 graphical interface, although with some differences in the correct detection of user interface properties. This work demonstrates the feasibility of a software tool to automate the counting of SNAP points.
