Symbiotic 6: generating test cases by slicing and symbolic execution

Symbiotic is a bug-finding and verification tool that integrates light-weight static analyses and instrumentation with program slicing and symbolic execution. The techniques are suitably combined according to a given goal. The paper describes a particular configuration competing in Test-Comp 2019. We also provide a brief analysis of Symbiotic ’s results achieved in the competition. As our tool uses a fork of the open-source symbolic executor Klee, we focus on comparison with mainstream Klee that also participated in the competition this year.
