Regression testing is an important activity for controlling the quality of a software product, but
it accounts for a large proportion of the costs of software. We believe that an understanding
of the underlying relationships in data about software systems, including data correlations
and patterns, could provide information that would help improve regression testing
techniques. We conjecture that if test cases have common properties, then test cases within
the same group may have similar fault detection ability. As an initial approach to …

software repositories, in this paper, we consider a clustering approach to help improve test …
