Abstract

This paper focused on finding reusable packages in an existing software system by measuring the required package metric to provide good quality of software. The metrics are ‘Coupling’, ‘Cohesion’, ‘Stability’ and ‘Complexity’ of a software module. The ‘Integration Testing’ takes important role to verify the connection among the modules to verify the message passing between the connected packages. Sending of messages from one package to another package the interfaces are required. Based on kind of dependency relationship the relation strength can be found to define the ‘import’ and ‘export’ coupling between packages. Those coupling values will be used for further calculation of ‘Instability’ of a package.  Complexity on a package will be done by verifying the method calling procedure among the package elements. These metrics are compared with the threshold value to keep the packages as suitable in further new software system.
