Testing polymorphic interactions in UML sequence diagrams

Nowadays UML based testing becomes more and more noteworthy, as UML is broadly accepted as de facto standard for object-oriented modeling language. A lot of researches propose test approaches for several types of UML diagrams, focusing on various viewpoints. An approach for testing polymorphic interactions, which are defined in UML sequence diagrams, is presented in this paper. From our observation, there are several forms of polymorphic interactions, which have their polymorphic behavior controlled by distinct factors. A method to test each form is determined from these factors. If an interaction is in one of the polymorphic forms defined in this paper, the factors that affect polymorphic behavior of the interaction can be addresses. Finally test cases for the interaction can be created for testing its polymorphic behavior.
