Journal ArticleDOI
Model checking programs
TL;DR: A verification and testing environment for Java, called Java PathFinder (JPF), which integrates model checking, program analysis and testing, and uses state compression to handle big states and partial order and symmetry reduction, slicing, abstraction, and runtime analysis techniques to reduce the state space.
Book ChapterDOI
Generalized symbolic execution for model checking and testing
TL;DR: In this paper, a source-to-source translation is defined to instrument a program, which enables standard model checkers to perform symbolic execution of the program and gives a novel symbolic execution algorithm that handles dynamically allocated structures (e.g., lists and trees), method preconditions (i.e., acyclicity), data (e, integers and strings) and concurrency.
Proceedings ArticleDOI
Test input generation with java PathFinder
TL;DR: The main contribution of this work is to show how efficient white-box test input generation can be done for code manipulating complex data, taking into account complex method preconditions.

TL;DR: Symbolic execution is a program analysis technique introduced in the 70s that has received renewed interest in recent years, due to algorithmic advances and increased availability of computational power and constraint solving technology.
Book ChapterDOI
JPF-SE: a symbolic execution extension to Java PathFinder
TL;DR: JPF-SE uses JPF to generate and explore symbolic execution paths and it uses off-the-shelf decision procedures to manipulate numeric constraints.
