Testing a configurable system with all possible configurations is very expensive and often impractical. For a single version of a configurable system, sampling approaches exist that select a subset of configurations from the full configuration space for testing. However, when a configurable system changes and evolves, existing approaches for regression testing select all configurations that are used to test the old versions for testing the new version. As demonstrated in our experiments, this retest-all approach for regression testing configurable systems turns out to be highly redundant. To address this redundancy, we propose a configuration selection approach for regression testing. Formally, given two versions of a configurable system, S (old) and S' (new), and given a set of configurations CS for testing S, our approach selects a subset CS' of CS for regression testing S'. Our study results on two open source systems and a large industrial system show that, compared to the retest-all approach, our approach discards 15% to 60% of configurations as redundant. Our approach also saves 20% to 55% of the regression testing time, while retaining the same fault detection capability and code coverage of the retest-all approach.","PeriodicalId":348790,"journal":{"name":"2012 28th IEEE International Conference on Software Maintenance (ICSM)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115705761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the performance of a system is often characterized by unexpected combinations of metric values, manual analysis of performance is hard in complex systems. In this paper, we extend our previous work on performance anomaly detection with a technique that helps performance experts locate spots - so-called performance improvement opportunities (PIOs) -, for possible performance improvements. PIOs give performance experts a starting point for performance improvements, e.g., by pinpointing the bottleneck component. The technique uses a combination of association rules and several visualizations, such as heat maps, which were implemented in an open source tool called Wedjat. In this paper, we evaluate our technique and Wedjat in a field user study with three performance experts from industry using data from a large-scale industrial application. From our field study we conclude that our technique is useful for speeding up the performance maintenance process and that heat maps are a valuable way of visualizing performance data.","PeriodicalId":348790,"journal":{"name":"2012 28th IEEE International Conference on Software Maintenance (ICSM)","volume":"136 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121888798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the other hand, some believe that refactoring has the risk of functionality regression and increased testing cost. This paper investigates the impact of refactoring edits on regression tests using the version history of Java open source projects: (1) Are there adequate regression tests for refactoring in practice? (2) How many of existing regression tests are relevant to refactoring edits and thus need to be re-run for the new version? (3) What proportion of failure-inducing changes are relevant to refactorings? By using a refactoring reconstruction analysis and a change impact analysis in tandem, we investigate the relationship between the types and locations of refactoring edits identified by RefFinder and the affecting changes and affected tests identified by the FaultTracer change impact analysis. The results on three open source projects, JMeter, XMLSecurity, and ANT, show that only 22% of refactored methods and fields are tested by existing regression tests. While refactorings only constitutes 8% of atomic changes, 38% of affected tests are relevant to refactorings. Furthermore, refactorings are involved in almost half of the failed test cases. These results call for new automated regression test augmentation and selection techniques for validating refactoring edits.","PeriodicalId":348790,"journal":{"name":"2012 28th IEEE International Conference on Software Maintenance (ICSM)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117057667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Researchers have proposed many techniques to detect, understand and eliminate code clones. However, due to lack of deeper understanding of reasons of cloning practices, especially from personal and organizational perspectives, little effective support can be provided to alleviate maintenance problems caused by code clones. In this paper, we report an industrial study on investigating reasons of cloning practices in large-scale software development from technical, personal, and organizational perspectives. Our study involves code analysis, questionnaire survey, and interviews with developers, and gathers solid empirical data about how developers clone and why during different phases of clones' lifecycle in industrial development. The results of our study suggest that cloning is not simply a technical issue; it must be interpreted and understood in larger context in which code clones occur and evolve. Within these contexts, there are several adjustable factors and two critical points that affect the introduction, existence, and removal of clones. These adjustable factors and critical points reveal opportunities to improve cloning practices in industrial development from technical, personal, and organizational perspectives.","PeriodicalId":348790,"journal":{"name":"2012 28th IEEE International Conference on Software Maintenance (ICSM)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114583567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

New features added to the common components of a software product family, are integrated into products following a selective code integration process. Selective code integration is a process in which developers pick the commits (i.e., code changes) related to a feature from one code branch and integrate them into another code branch. Developers often manually link the commits to the features to enable the selective integration of features. In current practice, not all dependent commits are always linked to features and developers might miss the unlinked commits during selective code integration. In this paper, we propose two grouping approaches that identify dependencies among commits and create groups of dependent commits that need to be integrated as a whole into a code branch. Our first approach is automatic and the other is developer-guided. Through a case study on data derived from a product line of mobile software applications, we show that our approaches can help to reduce by up to 94% integration failures caused by missing commit dependencies.","PeriodicalId":348790,"journal":{"name":"2012 28th IEEE International Conference on Software Maintenance (ICSM)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130810984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
