| Abstract: | In this century, computers have become an inseparable part of human life. Human beings entrust them with day-to-day activities and as well as highly sensitive data such as credit card information. Therefore, it is highly essential to ensure the proper working of the software before it is handed over to the users. Simple errors in the software may cause billions of dollar loss or even cause harm to human life. Therefore, the software needs to be dependable and reliable. Software testing is one of the most important methods to assure an error free software. This thesis work is centered on software testing. One of the major concerns in today’s practical software testing is the size of the source code which the testers have to deal with. Simple and effective testing methods that can handle the issue of source code length are highly essential. As the length of the program increases, testing activities like test case generation and test execution becomes more complicated. From the literature review it was evident that most of the existing methods for software testing did not address the problem of source code size during testing. Considering these scenarios, the work presented in this thesis tries to handle these challenges in practical software testing so as to make testing easier. With this aim, we have proposed a forward slicing based framework which helps to identify the statements of relevance in a software. Program slicing is used in several fields like program comprehension, debugging, software maintenance, program cohesion, refactoring and reverse engineering. Anyhow, the works that explicitly demonstrate how program slicing may be applied in software testing is extremely rare. In this thesis, we have clearly demonstrated how to perform software testing and trace dependencies in the source code using forward slicing. A formal representation of forward slicing is also presented in this work. As an extension to our forward slicing framework, we have also introduced the concept of partitioned forward slices and partial slices which helps the testers to focus on statements of interest. Partitioned forward slices helps to handle the large size of forward slices whereas partial slices identifies statements of interest with respect to output variables. The research finding finally concludes that, software testing approaches should incorporate slicing methods to make testing more effective and easier. |
