A Firewall Approach for the Regression Testing of Object-Oriented Software

A firewall model has been developed to provide for regression testing at the integration level for small changes in OO-software, which accounts for polymorphism and other dynamic elements of reuse. The firewall is a virtual boundary which encloses the set of classes (or objects) that must be retested after this change. It will be shown that changes in the specification of a class should be treated differently than the simple change of code of that class.

The general approach is to first construct the class firewall from static characteristics of the design or code, followed by the construction of a part of the object firewall if polymorphism or other dynamic elements must be resolved; the results of the object firewall can then be reflected back into the class firewall, often resulting in simplification. The model can deal with all class relationships encountered during analysis and design phases, in addition to inheritance and polymorphism. Experiments with this model using Java and C++ programs are currently being conducted.
