Validation of dynamic coupling metrics for object-oriented software

Dynamic coupling metrics for object-oriented software provide scope of coupling measurement up to the object level and take into account important and widely used object-oriented features such as inheritance, polymorphism and dynamic binding during measurement. The dynamic measures are computed at run-time, which take into consideration the actual interactions taking place among members of a class. In this paper, an attempt has been made to evaluate dynamic coupling metrics for object-oriented software using formal evaluation framework proposed by Briand et al. A practical and useful coupling measure must satisfy most of the properties given in this framework. The results of this study show that dynamic coupling metrics satisfy all properties and parameters required by the evaluation framework and thus dynamic coupling measures are robust and useful.
