Abstract

In this paper we present Oprop, a tool that implements the theory of object propositions. We have recently introduced object propositions as a modular verification technique that combines abstract predicates and fractional permissions. The Oprop tool, found as a web application at lowcost-env.ynzf2j4byc.us-west-2.elasticbeanstalk.com, verifies programs written in a simplified version of Java augmented with the object propositions specifications. Our tool parses the input files and automatically translates them into the intermediate verification language Boogie, which is verified by the Boogie verifier that we use as a back end. We present the details of our implementation, the rules of our translation and how they are applied on an example. We describe an instance of the challenging Composite design pattern, that we have automatically verified using the Oprop tool, and prove the equivalence between formulas in Oprop and their translation into Boogie.
