We present, in this paper, a new metric capturing in an integrated way different attributes of object-oriented systems. The metric uses basically control flow paths and probabilities. It captures the interactions between classes and related control. The study presented in this paper aims at exploring empirically the relationship between the proposed metric and testability of classes. We investigate testability from the perspective of unit testing. We designed and conducted an empirical study using data collected from two open source Java softwaresystems for which JUnit test cases exist. To capture testability of classes, we used different metrics to quantify the corresponding JUnit test cases. In order to evaluate the capability of the new metric to predict testability of classes, we used statistical tests using correlation. The achieved results provide evidence that there exist a significant relationship between the proposed metric and testability of classes.
We present an approach to propagation based SAT encoding, Boolean equi-propagation, where constraints are modelled as Boolean functions which propagate information about equalities between Boolean literals. This infor...

Metric is extremely important for software development. It is a tool for measuring software in both quantitative and qualitative aspects. In addition, metric can be used for determining an achievement of the goals. There are some problems that bring difficulties to the design and development of software metrics. Among them, a number of software perspectives that metrics must handle and the way to apply metrics results to support business outcomes are considered important. This paper proposes OPI as a model for implementing software metrics based on business outcomes. There are three steps in this model, defining outcomes (O), defining perspectives (P), and defining indicators (I). A case study has been developed to assess the use of the proposed model. Forty undergraduate students, who have basic knowledge in software metric, use the model to develop metrics from the case study. The preliminary evaluation is based on usability aspect. The result has show that 85 percents of the students think that the model is easy to understand, where 8 and 7 percents say that it is moderate and hard respectively.

The share measure has been proposed as an important measure for mining association rules. The value of share itemsets provides useful information such as total profits and total customer purchased quantities associated with itemsets in database. The share-frequent itemsets mining problems become a very important research issue in data mining. Existing share-frequent itemsets mining algorithms are based on static database so knowledge must be rebuilded when the minimum share threshold is changed or database is modified either appended or updated. This paper proposes a novel BitTable knowledge for incremental and interactive share-frequent itemsets mining in multiple minimum share thresholds without rebuilding BitTable knowledge. It is effective for incremental and interactive mining to take advantage of the previous BitTable knowledge and the previous mining results.
