Proposal for Control Dependency White-Box Test Coverage Metrics for Inheritance

Abstract

Several white-box test coverage metrics have been proposed in the literature in the context of object-oriented programs. However, these are not appropriate for the objectoriented feature inheritance. The main reason for this situation is the fact that a class is derived from another class in inheritance. Though there are a large number of well established test coverage metrics have been reported to capture the coverage of objectoriented programs, white-box test coverage metrics to capture the coverage due to inheritance have rarely been reported. In this paper, we propose a set of novel unit test coverage metrics for object-oriented feature inheritance based on execution of control dependences of the JSysDG (Java System Dependency Graph).
