Context: The goal of this research is to form a correlation between code packages and test cases which is done by using automated weak mutation. The correlations formed is used as the statistical test data for selecting relevant tests from the test suite which decreases the size of the test suite and speed up the process. Objectives: In this study, we have done an investigation of existing methods for reducing the computational cost of automatic mutation testing. After the investigation, we build an open source automatic mutation tool that mutates the source code to run on the test cases of the mutated code that maps the failed test to the part of the code that was changed. The failed test cases give the correlation between the test and the source code which is collected as data for future use of the test selection. Methods: Literature review and Experimentation is chosen for this research. It was a controlled experiment done at the Swedish ICT company to mutate the camera codes and test them using the regression test suite. The camera codes provided are from the continuous integration of historical data. We have chosen experimentation as our research because as this method of research is more focused on analyzing the data and implementing a tool using historical data. A literature review is done to know what kind of mutation testing reduces the computational cost of the testing process. The implementation of this process is done by using experimentation Results: The comparative results obtained after mutating the source code with regular mutants and weak mutants we have found that regular mutants and weak mutants are compared with their correlation accuracy and we found that on regular mutation operators we got 62.1% correlation accuracy and coming to weak mutation operators we got 85% of the correlation accuracy. Conclusions: This research on experimentation to form the correlations in generating test selection statistics using automated mutation testing in the continuous integration environment for improving test cases selection in regression testing
