Web sites are becoming increasingly complex as more and more services and information are made available over the Internet and intranets. At the same time, the correct behavior of sites has become crucial to the success of businesses and organizations and thus should be tested thoroughly and frequently. This paper presents a technique that uses code to automatically generate its own test cases at run-time by using a combination of symbolic and concrete (i.e., regular) execution. The input values to a program (or software component) provide the standard interface of any testing framework with the program it is testing, and generating input values that will explore all the interesting behavior in the tested program remains an important open problem in software testing research.
