Concolic testing implementors noticed that implementation of full-fledged symbolic execution can be avoided if symbolic execution can be piggy-backed with the normal execution of a program through instrumentation. The symbolic state is used for checking properties on the software, while the concrete state is used to avoid reaching unreachable state.

Increasingly these technologies are being used by many security companies and hackers alike to find security vulnerabilities. In a concolic model checker, the model checker traverses states of the model representing the software being checked, while storing both a concrete state and a symbolic state.

This page was last edited on 28 Septemberat Retrieved from " https: A concolic unit testing engine for C", [2] by Koushik Sen, Darko Marinov, and Gul Agha, further extended the idea to data structures, and first coined the term concolic testing. This input reaches the error. Concurrently, the symbolic execution follows the same path but treats x and y as symbolic variables. Dill; Dawson Engler Tesying description cuute discussion of the concept was introduced in "DART: From Wikipedia, the free encyclopedia.

CUTE and jCUTE: Concolic Unit Testing and Explicit Path Model-Checking Tools

Levin; David Molnar Its main focus is finding bugs in real-world software, rather than demonstrating program correctness. The concolic approach is also applicable to model checking.

Automated theorem proving Software testing. This idea of simplifying implementation of symbolic execution gave birth to 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. Symbolic-execution based analysis and testing, in general, has witnessed a significant level of interest from industry [ citation needed ].

Haifa Verification Conference Concolic testing a portmanteau of concrete and symbolic is a hybrid software verification technique that performs symbolic executiona classical technique that treats program variables as symbolic variables, along a concrete execution testing on particular inputs path.

This inequality is called a path condition and must be true for all executions following the same execution path as the current one. 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 testimg and expressive power of SMT Solvers. All articles with unsourced statements Articles with unsourced statements from January Articles with unsourced statements from March Simple random testing, trying random values of x and ywould require an impractically large number of tests to reproduce the failure.

Perhaps the most famous commercial tool that uses dynamic symbolic execution aka concolic testing is the Cut tool from Microsoft. Proceedings of the 2nd international workshop on Random testing: Views Read Edit View history. 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.
