Data and Control Flow Analysis of VDMµ Specifications

Authors: Mubina Nazmeen, Iram Rubab


Formal Specification languages are being widely used for system specification and testing. Highly critical systems such as real time systems, avionics, and medical systems are represented using Formal specification languages. Formal specifications based testing is mostly performed using black box testing approaches thus testing only the set of inputs and outputs of the system. The formal specification language such as VDMµ can be used for white box testing as they provide enough constructs as any other high level programming language. In this work, we perform data and control flow analysis of VDMµ class specifications. The proposed work is discussed with an example of SavingAccount.

Keywords: Testing, formal specification, VDM-SL, VDMµ, data flow graph, control flowgraph
