Our work on narrowing the gap between verification and systematic testing has two directions: (1) complementing verification with systematic testing, and (2) pushing systematic testing toward reaching verification. In the first direction, we explore how to effectively combine static analysis with systematic testing, so as to guide test generation toward properties that have not been previously ...

In this paper, we used a simple metric (i.e. Lines of Code) to measure the complexity involved in software verification and software testing. The goal is then, to argue for software verification over software testing, and motivate a discussion of how to reduce the complexity involved in software verification. We propose to reduce this complexity by translating the software to a simple intermedi...

Abstract Korn is a software verifier that infers correctness certificates and violation witnesses sutomatically using state-of-the-art Horn-clause solvers, such as Z3 Eldarica. The solvers are used in portfolio together with cheap random sampling where the latter can be very effective at finding counterexamples. perfomend best sub-category of SV-COMP 2023.

Software is used in many safetyand security-critical systems. Software development is, however, an error-prone task where a software developer tries to precisely formalize in a programming language their imprecise ideas about a program. Formal methods help to reduce this problem. These methods add another layer to the software development allowing to formalize and to check desired properties of...

Model checking is the verification approach for proving a satisfaction of desired properties on a finite state system model. Whenever a new feature (aspect) which is developed as a separated unit is composed to the original software for evolving to the next generation, the properties which held on the model of the original software should be re-checked for their preservation. The re-verificatio...

Security and performance are critical software non-functional requirements. Therefore, verification activities should be included in the development process to identify related defects, avoiding failures after deployment. However, there is a lack of understanding on factors moderating security verification, which jeopardizes organizations improve their assure releasing fulfilling these To moder...
