Applying conventional testing techniques for class testing

We discuss how conventional testing criteria such as branch coverage can be applied to the testing of member functions inside a class. To support such testing techniques we employ symbolic execution techniques and finite state machines (FSMs). Symbolic execution is performed on the code of a member function to identify states that are required to fulfil a given criterion. We use FSMs to generate a sequence of member functions leading to the identified states. Our technique is a mixture of code-based and specification-based testing techniques in the sense that it uses information derived from codes using symbolic execution together with information from specifications using FSMs for testing activities.
