Runtime assertion checking and its combinations with static and dynamic analyses tutorial synopsis

Conference of 8th International Conference on Tests and Proofs, TAP 2014, Held as Part of the Software Technologies: Applications and Foundations, STAF 2014 ; Conference Date: 24 July 2014 Through 25 July 2014; Conference Code:106534International audienceAmong various static and dynamic software verification techniques, runtime assertion checking traditionally holds a particular place. Commonly used by most software developers, it can provide a fast feedback on the correctness of a property for one or several concrete executions of the program. Quite easy to realize for simple program properties, it becomes however much more complex for complete program contracts written in an expressive specification language. This paper presents a one-hour tutorial on runtime assertion checking in which we give an overview of this popular dynamic verification technique, present its various combinations with other verification techniques (such as static analysis, deductive verification, test generation, etc.) and emphasize the benefits and difficulties of these combinations. They are illustrated on concrete examples of C programs within the Frama-C software analysis framework using the executable specification language E-ACSL
