This paper introduces a distributed execution framework for JUnit test cases called HadoopUnit, which is built upon Hadoop: an open-source platform for running applications that process vast amounts of data on large clusters built of commodity hardware. The primary motivation behind developing HadoopUnit was to test Hadoop production code using the Hadoop platform itself: existing approaches to testing the system were taking too long to run to completion, and were unable to provide feedback to the developers in a timely manner. Preliminary results suggest that HadoopUnit can reduce test execution time significantly: a 150-node cluster has produced a 30x improvement. HadoopUnit can be used by anyone for testing an application as long as they have access to a computing cluster with the Hadoop software installed and running.","PeriodicalId":247441,"journal":{"name":"2009 IEEE International Conference on Software Maintenance","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130078861","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}

When source code evolves, clone management requires a mechanism to efficiently and incrementally detect code clones in the new revision. This paper introduces an incremental clone detection tool, called ClemanX. Our tool represents code fragments as subtrees of Abstract Syntax Trees (ASTs), measures their similarity levels based on their characteristic vectors of structural features, and solves the task of incrementally detecting similar code as an incremental distance-based clustering problem. Our empirical evaluation on large-scale software projects shows the usefulness and good performance of ClemanX.","PeriodicalId":247441,"journal":{"name":"2009 IEEE International Conference on Software Maintenance","volume":"180 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124498941","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}

Furthermore, developers do not usually retain a good design in favor of adding new features, comply with requirements or meet deadlines. For these reasons, code can become rather complex and difficult to understand. More particularly in object-oriented systems, classes may become very large and less cohesive. In order to identify such problematic cases, existing approaches have proposed the use of cohesion metrics. However, while metrics can identify classes with low cohesion, they cannot identify new or independent concepts. Moreover, these methods require a lot of human interpretation to identify the respective design flaws. In this paper, we propose a class decomposition method using an agglomerative clustering algorithm based on the Jaccard distance between class members. Our methodology is able to identify new concepts and rank the solutions according to their impact on the design quality of the system. Finally, our method has been evaluated by two independent designers who were asked to comment on the suggestions produced by our technique on their projects. The designers provided feedback on the ability of the method to identify new concepts and improve the design quality of the system in terms of cohesion.","PeriodicalId":247441,"journal":{"name":"2009 IEEE International Conference on Software Maintenance","volume":"444 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133568075","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}

The technique searches for program statements involving values that can be altered during runtime to cause the incorrect output of a failing run to become correct. We showed that highly effective fault localization results could be achieved by the technique on programs containing single faults. In the current work, we generalize Value Replacement so that it can also perform effectively in the presence of multiple faults. We improve scalability by describing two techniques that significantly improve the efficiency of Value Replacement. In our experimental study, our generalized technique effectively isolates multiple simultaneous faults in time on the order of minutes in each case, whereas in [9], the technique had sometimes required time on the order of hours to isolate only single faults.","PeriodicalId":247441,"journal":{"name":"2009 IEEE International Conference on Software Maintenance","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115577073","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}

Thus, it is of great research and practical interest to learn about the characteristics on how IDE features change and mature. To this end, we have conducted an empirical study, analyzing a total of 645 “What's New” release note entries in 7 releases of the Eclipse IDE both quantitatively and qualitatively. It is found that majority of the changes are refinements or incremental additions to the feature architecture set up in early releases (1.0 and 2.0). Motivated by this, a further analysis on usability is performed to characterize how these changes impact programmers effectiveness in using the IDE. We summarize our study methodology and lessons learned.","PeriodicalId":247441,"journal":{"name":"2009 IEEE International Conference on Software Maintenance","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129714627","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}
