Studying the co-evolution of production and test code in open source and industrial developer test processes through repository mining

Andy Zaidman, Bart Van Rompaey, Arie van Deursen, Serge Demeyer
2010 Empirical Software Engineering  
Many software production processes advocate rigorous development testing alongside functional code writing, which implies that both test code and production code should co-evolve.  ...  We validate these views against two open source and one industrial software project and evaluate our results both with the help of log messages, code inspections and the original developers of the software  ...  Acknowledgements Our gratitude goes out to the Software Improvement Group 8 (SIG) for providing us with the opportunity and the support to analyze one of their software systems; in particular we would  ...

Natural language processing in mining unstructured data from software repositories: a review

Som Gupta, S K Gupta
2019 Sadhana (Bangalore)  
More than 80 percent of the data present in them is unstructured. Mining data from these repositories helps project managers, developers and businesses, in getting interesting insights.  ...  Most of the software artefacts present in these repositories are in the natural language form, which makes natural language processing (NLP) an important part of mining to get the useful results.  ...  Mining these repositories not only helps get insights about the processes but also helps in decision-making in terms of both the product and process for further enhancements and improvements.  ...

Mining micro-practices from operational data

Minghui Zhou, Audris Mockus
2014 Proceedings of the 22nd ACM SIGSOFT International Symposium on Foundations of Software Engineering - FSE 2014  
We propose a large-scale evidence-based approach to accomplish this by first creating a mirror of the projects in the open source universe.  ...  The next step would involve the inductive generalization from in-depth studies of specific projects from one side and the categorization of micro-practices in the entire universe from the other side.  ...  Considering the extensive extent of code reuse in OSS communities, it's of interest to devote research effort to the co-evolution problems across projects, e.g., feature implementation and bug fix merging  ...

How Maintainability Issues of Android Apps Evolve

Ivano Malavolta, Roberto Verdecchia, Bojan Filipovic, Magiel Bruntink, Patricia Lago
2018 2018 IEEE International Conference on Software Maintenance and Evolution (ICSME)  
We designed and conducted an empirical study on 434 GitHub repositories containing open, real (i.e., published in the Google Play store), and actively maintained Android apps.  ...  Together, these results can help Android developers in (i) better planning code refactoring sessions, (ii) better planning their code review sessions (e.g., steering the assignment of code reviews), and  ...  Source code quality tools. In order to minimize maintenance costs, developers can track and improve their source code quality with the help of open-source tools.  ...
