Practical approach for model based slicing

Abstract

Software testing is an activity that aims at evaluating an attribute or capability of system and determining that whether it meets required expectations. The most intellectually challenging part of testing is the design of test cases. Test case generation from design specifications has the added advantage of allowing test cases to be available early in the software development cycle. Now days, UML has been widely used for object oriented modeling and design. This is due to the fact that UML metamodel extends support to describe structural and behavioral aspects of an architecture. However, it is still difficult to understand this behavior, because the size of automatically generated model diagrams tends to be huge. To overcome this problem of software visualization model based slicing technique came into existence. Model based slicing is a decomposition technique to extract and identify relevant model parts or related elements across diverse model views. We have proposed a novel methodology to extract the submodel from a big model diagrams on the basis of slicing criteria. The proposed methodology use the concept of model based slicing to slice the sequence diagram to extract the desired chunk. In the presented approach UML, conversion of UML into XML, Java DOM API for parsing and slicing has been used.
