Concolic Testing (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Concolic testing is a hybrid software verification technique that interleaves concrete execution with symbolic execution, a classical technique that treats program variables 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 with the aim of maximizing code coverage. Its main focus is finding bugs in real-world software, rather than demonstrating program correctness. The first tool of this type was PathCrawler. Another tool, called EXE, based on similar ideas was independently developed by Professor Dawson Engler's group at Stanford University in 2005, and published in 2005 and 2006. The concept of concolic testing was also independently developed by Koushik Sen at the University of Illinois at Urbana-Champaign and Patrice Godefroid of the AT&T Bell Labs in 2005 in their tool called DART.
