CUTE and jCUTE: Concolic Unit Testing and Explicit Path Model-Checking Tools
All cufe with unsourced statements Articles with unsourced statements from January Articles with unsourced statements from March Levin; David Molnar Concolic testing implementors noticed that implementation of full-fledged symbolic execution can be condolic if symbolic execution can be piggy-backed with the normal execution of a program through instrumentation.
An important reason for the rise of concolic testing and more generally, symbolic-execution based analysis of programs in the decade since it was introduced in is the dramatic improvement in the efficiency and expressive power of SMT Solvers.
This input reaches the error. A concolic unit testing engine for C”,  by Koushik Convolic, Darko Marinov, and Gul Agha, further extended the idea to data structures, and first coined the term concolic testing. An automated theorem prover is then invoked to find values for the input variables x and y given the complete set of symbolic variable values and path conditions constructed during symbolic execution.
Dill; Dawson Engler Views Read Edit View history. Implementation of traditional symbolic execution based testing requires the implementation of a full-fledged symbolic interpreter for a programming language. Its main focus is finding bugs in real-world software, rather than demonstrating program correctness.
The symbolic state is used for checking properties on the software, while the concrete state is used to avoid reaching unreachable state. Symbolic-execution based analysis and testing, in general, has witnessed a significant level of interest from industry [ citation needed ].
A description and discussion of the concept was introduced in “DART: Concolic testing a portmanteau of concrete and symbolic is a hybrid software verification technique cuute performs symbolic executiona classical technique that treats program variables as symbolic variables, along a concrete execution testing on particular inputs path. Simple random testing, trying random values of x and ywould require an impractically large number of tests to reproduce the failure.

From Wikipedia, the free encyclopedia. Proceedings of the 2nd international workshop on Random testing: Increasingly these technologies are being used by many security companies and hackers alike to find security vulnerabilities.
This page was last edited on 28 Septemberat Concurrently, the symbolic execution follows the same path but treats cuute and y as symbolic variables. Symbolic execution is used in conjunction with an automated theorem prover or constraint solver based on constraint logic programming to generate new concrete inputs test cases with the aim of maximizing code coverage.
Automated theorem proving Software testing.
Haifa Verification Conference This inequality is called a path condition and must be true for all executions following the same execution path as the current one. Archived from the original PDF on In a concolic model checker, the model checker traverses states of the model representing the software being checked, while storing both a cutee state and a symbolic state. The concolic approach is also applicable to model checking.
