Symbolic execution path explosion

Websingle path traveled by a concrete execution. The collected symbolic path constraints of the branches along the path are then incrementally negated, which results in new path constraints that can be solved for new test inputs that cover other paths. Although … Weband symbolic execution, are highly effective [Cadar 2008, Holzmann 2008], but their adoption in industrial general-purpose software testing has been limited. We blame this gapbetween researchand practiceon three challengesfaced byautomatedtesting:scalability,applicability,andusability. First, path explosion—the fact …
