Cooperative Test-Case Generation with Verifiers

Dirk Beyer, Marie-Christine Jakobs
2020 Software Engineering  
It iteratively executes a sequence of verifiers that may exchange analysis information between each other and output a test case whenever they reach a test goal.  ...  We propose the hybrid test-generation approach CoVeriTest. CoVeriTest is flexible, cooperative, and based on verification technology.  ...  In each iteration, veriĄer i is run for t i time units and adds its generated test cases to the global test suite.  ...

CoVeriTest: interleaving value and predicate analysis for test-case generation

Marie-Christine Jakobs
2020 International Journal on Software Tools for Technology Transfer (STTT)  
Verification techniques are well-suited for automatic test-case generation. They basically need to check the reachability of every test goal and generate test cases for all reachable goals.  ...  For Test-Comp'19, we support the set of all __VERIFIER_error() calls as well as the set of all branches. Thus, we can deal with the two test specifications considered in Test-Comp'19.  ...  Co-operative, verifier-based testing iteratively combines different verification techniques for test-case generation.  ...
