How Test Generation Helps Software Specification and Deductive Verification in Frama-C

International audienceThis paper describes an incremental methodology of deductive verification assisted by test generation and illustrates its benefits by a set of frequent verification scenarios. We present StaDy, a new integration of the concolic test generator PathCrawler within the software analysis platform FramaC. This new plugin treats a complete formal specification of a C program during test generation and provides the validation engineer with a helpful feedback at all stages of the specification and verification tasks
