TLDR
A verification and testing environment for Java, called Java PathFinder (JPF), which integrates model checking, program analysis and testing, and uses state compression to handle big states and partial order and symmetry reduction, slicing, abstraction, and runtime analysis techniques to reduce the state space.Abstract:
The majority of the work carried out in the formal methods community throughout the last three decades has (for good reasons) been devoted to special languages designed to make it easier to experiment with mechanized formal methods such as theorem provers and model checkers. In this paper, we give arguments for why we believe it is time for the formal methods community to shift some of its attention towards the analysis of programs written in modern programming languages. In keeping with this philosophy, we have developed a verification and testing environment for Java, called Java PathFinder (JPF), which integrates model checking, program analysis and testing. Part of this work has consisted of building a new Java Virtual Machine that interprets Java bytecode. JPF uses state compression to handle large states, and partial order reduction, slicing, abstraction and run-time analysis techniques to reduce the state space. JPF has been applied to a real-time avionics operating system developed at Honeywell, illustrating an intricate error, and to a model of a spacecraft controller, illustrating the combination of abstraction, run-time analysis and slicing with model checking.read more

DiVM: Model checking with LLVM and graph memory
TL;DR: In this paper, the authors introduce the concept of a virtual machine with graph-organised memory as a versatile backend for both explicit-state and abstraction-driven verification of software, using the LLVM IR as its instruction set, enriched with a small set of hypercalls.

Formal testing for separation assurance
TL;DR: This paper discusses three different approaches to test-case generation, their application to a separation assurance prototype, and their respective strengths and weaknesses, and presents an approach for statistical analysis of the large numbers of test results obtained from the framework.

Learning-based assume-guarantee verification (tool paper)
TL;DR: This paper focuses on model checking on the basis of assumption-guarantee reasoning, which is a widespread “divide-and-conquer” approach that uses assumptions when checking individual components of a system.
Efficient dynamic verification algorithms for mpi applications
TL;DR: This dissertation provides a formal model forMPI, and introduces a tailor-made notion of Happens-Before ordering for MPI functions, which elegantly solves all four problems of MPI.

Statecharts: A visual formalism for complex systems
TL;DR: It is intended to demonstrate here that statecharts counter many of the objections raised against conventional state diagrams, and thus appear to render specification by diagrams an attractive and plausible approach.
