Automatic testing of symbolic execution engines via program generation and differential testing

Timotej Kapus, Cristian Cadar
2017 2017 32nd IEEE/ACM International Conference on Automated Software Engineering (ASE)  
When combined with existing program generation techniques and appropriate oracles, this approach enables differential testing within a single symbolic execution engine.  ...  The approach used relies on a novel way to create program versions, in three different testing modes-concrete, single-path and multi-path-each exercising different features of symbolic execution engines  ...  ACKNOWLEDGEMENTS We would like to thank the authors of Csmith for their assistance using the tool, the developers of CREST, FuzzBALL and KLEE for their feedback on our bug reports, and Frank Busse, Andrea  ...

Software regression as change of input partitioning

Marcel Bohme
2012 2012 34th International Conference on Software Engineering (ICSE)  
The main target of our research is to develop strategies for the automatic evolution of a test suite that does inspire confidence.  ...  When the program is changed, test cases shall be augmented that witness changed output for the same input (test suite augmentation).  ...  Using dynamic program dependencies, symbolic execution, and constraint solving, test cases are automatically generated that witness "adjacent" partitions.  ...

Shadow of a doubt

Hristina Palikareva, Tomasz Kuchta, Cristian Cadar
2016 Proceedings of the 38th International Conference on Software Engineering - ICSE '16  
In this paper, we present a symbolic execution-based technique that is designed to generate test inputs that cover the new program behaviours introduced by a patch.  ...  During this combined shadow execution, whenever a branch point is reached where the old and the new version diverge, we generate a test case exercising the divergence and comprehensively test the new behaviours  ...  The technique unifies the two program versions via change annotations, maximises sharing between the symbolic stores of the two versions, and focuses exactly on those paths that trigger divergences.  ...

Many of these techniques are based on dynamic symbolic execution [8], a program analysis technique that provides the ability to generate inputs that form high-coverage test suites.  ...  The main contributions of this work are: Fig. 1. A toy example illustrating symbolic execution. OVERVIEW Shadow symbolic execution is meant to augment an existing test suite of a program.  ...  ACKNOWLEDGMENTS We thank Paul Marinescu and Daniel Liew for their assistance during this project, and Frank Busse, Alastair Donaldson, Sophia Drossopoulou, Antonio Filieri, Timotej Kapus, Andrea Mattavelli  ...

Analysing the program analyser

Cristian Cadar, Alastair F. Donaldson
2016 Proceedings of the 38th International Conference on Software Engineering Companion - ICSE '16  
Inspired by recent advances in compiler testing, we set out initial steps towards this vision, building upon techniques such as cross-checking, program transformation and program generation.  ...  The reliability of program analysis tools is clearly important if such tools are to play a serious role in improving the quality and integrity of software systems, and the confidence which users place  ...  via EP/L002795/1.  ...

Overfitting in semantics-based automated program repair

Xuan Bach D. Le, Ferdian Thung, David Lo, Claire Le Goues
2018 Empirical Software Engineering  
Semantics-based APR uses symbolic execution and test suites to extract semantic constraints, and uses program synthesis to synthesize repairs that satisfy the extracted constraints.  ...  Heuristic-based APR generates large populations of repair candidates via source manipulation, and searches for the best among them.  ...  Acknowledgements We thank the authors of Angelix for making the tool publicly available. We also thank the authors of CVC4 and Enumerative synthesis engines for making these engines accessible.  ...
