Thesis Work - Evaluating KLEE on a production codebase i Göteborg

Welcome to explore the world of Volvo Cars by authoring your thesis with us! As a thesis worker in our organization, you are supported by a supervisor who follows you during your project. All thesis projects are arranged in business-critical areas and therefore you will be able to contribute to our company's purpose – providing freedom to move in a safe, sustainable, and personal way – from day one!

KLEE is a symbolic execution engine. It analyzes a program, assumes symbolic values for and generates expressions for the detected symbols and constraints of the program. The different possible inputs that may trigger an execution branch are determined by solving these constraints. KLEE is a dynamic symbolic execution engine built on top of the LLVM.

As part of this work, we want to develop tooling and infrastructure around KLEE and some of our codebases and document the performance and limitations of using it. We also want to use KLEE to extend the testing infrastructure by automatic test-case generation and code visualization.

We want to evaluate KLEE for inclusion in our tooling infrastructure. We want to do so by evaluating its behavior on a small representative subset of our codebase. We do so by creating special compile targets, use llvm and docker, and in some cases instrument certain parts of the codebase, to integrate the tool to the codebase. As part of this thesis, we want to evaluate this experience while doing automatic test-case generation. Finally, we want to compare the generated tests versus existing tests.

Note that we aim to publish any results on the next year's KLEE workshop.
