Software Testing and Debugging Techniques

Today almost all the software industries are overloaded with the maintenance work of already developed software.When any new demand of software arrives, company matches the new problem with the existing product, so that the new product can be easily developed with some new modification in existing products.The reuse of the existing product is only possible when it is measured accurately and efficiently for a longer period.In this paper, first we will calculate the class level metrics viz.CBO, RFC, WMC etc for the entire package then we will calculate the average value for each class level metric (selected) by dividing the value for each metric from the total number of classes for each package.The new resultant metrics are named as CBO avg , RFC avg , WMC avg and so on.The importance of these metrics is to accurately measure the complexity at package level.We then map these package level class metrics with the quality attributes and finally validate these metrics upon three open source projects i.e.Jedit, FreeCS and Llamma chart.Data extraction has been done through an automated tool JHawk and analysis of data has been done using SPSS 10.0 as statistical tool.
