WebSep 7, 2024 · Concolic testing combines program execution and symbolic analysis to explore the execution paths of a software program. This paper presents the first concolic testing approach for Deep Neural Networks (DNNs). More specifically, we formalise coverage criteria for DNNs that have been studied in the literature, and then develop a … WebConcolic testing executes a program starting with some given or random input, gathers symbolic constraints on inputs at conditional statements along the execution, and then uses a constraint solver to infer variants of the previous inputs in order to steer the next execution of the program toward an alternative feasible execution path.

WebDec 3, 2024 · Abstract: We present hybrid concolic testing, an algorithm that interleaves random testing with concolic execution to obtain both a deep and a wide exploration of program state space. Our algorithm generates test inputs automatically by interleaving random testing until saturation with bounded exhaustive symbolic exploration of program …
WebConcolic testing, also known as dynamic symbolic execution, is an integration of concrete execution (a.k.a. testing) with symbolic execution [22, 41]. Concrete execution and symbolic execution nat-urally complement each other. On one hand, concrete execution is computationally cheap.
