Abstract:
: In this paper we investigate the correlation between test coverage, mutation score and object-oriented systems metrics. First we conducted a literature review to obtain an initial model of testability and existing object-oriented metrics related to testability. Thus we selected four open source system whose test cases were available and calculated the correlation between the metrics collected and the line coverage, branches coverage and mutation score. Preliminary results show that some CK metrics, which are strongly related to system’s design, influence mainly line coverage and mutation score, thus they can influence systems testability.
