In code-based development contexts this activity has been widely studied, whereas in model-driven ones, where models are first-class development entities, there are many issues yet to be tackled. In this paper we present a metamodel that supports the specification of pre- and post- conditions of model refactoring actions, and the automated derivation and verification of such conditions in specific modeling languages. Our work is aimed at helping users to implement refactoring actions in the adopted modelling language by providing an environment for guaranteeing the feasibility of refactoring actions. Our primary focus is on the definition of applicable sequences of refactoring actions, rather than on the user-driven step-by-step application of refactoring actions. As an example, we illustrate the applicability of our metamodel for UML models refactoring.","PeriodicalId":404412,"journal":{"name":"Proceedings of the 2nd International Workshop on Refactoring","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125009639","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}

Code refactoring received a great attention in the literature, often directed to the refactoring of code smells. While at the architectural level, architectural smells received less attention. One of the most common architectural smell which may affect many parts of a software application is the Cyclic Dependency smell. This position paper presents a tool prototype that suggests which path a developer could follow to remove Cyclic Dependency smells in Java applications. The tool has been developed as an extension of the Arcan tool for architectural smells detection. In this paper we describe how the tool identifies the path to follow for the refactoring of Cyclic Dependency on real projects. The tool has been thought only to suggest a possible refactoring approach which a developer could considerate to resolve Cyclic Dependency.","PeriodicalId":404412,"journal":{"name":"Proceedings of the 2nd International Workshop on Refactoring","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128636750","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}

In this context, the purpose of this paper is to better understand developer familiarity and comfort with these languages by conducting a survey. It poses, and answers, four research questions to understand how frequently source code transformation languages are applied to refactoring tasks, how well-known these languages are in industry, what developers think are obstacles to adoption, and what developer refactoring habits tell us about their current use, or underuse, of transformation languages. The results show that while source code transformation languages can fill a needed niche in refactoring, research must motivate their application. We provide explanations and insights based on data, aimed at the program transformation and refactoring communities, with a goal to motivate future research and ultimately improve industry adoption of transformation languages for refactoring tasks.","PeriodicalId":404412,"journal":{"name":"Proceedings of the 2nd International Workshop on Refactoring","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127977155","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}

An approach based on clustering ensembles is proposed, several heuristics to existing algorithms and to filtering and combining their results are discussed. Experimental validation of the proposed approach on an open source project is presented. The obtained preliminary results illustrate that the introduced approach could be successfully used to improve existing integrated development environments, providing developers with one more tool to reduce the complexity of their projects. The paper concludes with a discussion on the applicability of such automatic refactoring recommendation approaches to real-world software developed using common object-oriented techniques.","PeriodicalId":404412,"journal":{"name":"Proceedings of the 2nd International Workshop on Refactoring","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128296564","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}

However, when refactoring the test suite itself, there is no such safeguard. Therefore, there is a need for tool support that can verify if a refactored test suite preserves its behaviour pre- and post-refactoring. In this work we present T-CORE (Test COde REfactoring tool); a tool that captures the behaviour of Java tests in the form of a Test Behaviour Tree. T-CORE allows developers to verify that the refactoring of a test suite has preserved the behaviour of the test.","PeriodicalId":404412,"journal":{"name":"Proceedings of the 2nd International Workshop on Refactoring","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132584376","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}

Developers rename entities when their original names no longer fit their behavioral role within the program. This may happen if the entity's original name was of poor quality or if the system has evolved such that the original name needs to be updated to reflect some of this evolution. In the end, the reason for the rename ultimately falls under increasing understandability and comprehension. Because comprehension is so important, and identifiers are the primary way developers comprehend code, it is critical to understand empirically how and why identifier names evolve. Armed with an understanding of these two facets of identifier evolution, researchers will be able to train algorithms to recognize, recommend, or even automatically generate high-quality identifier names. We present an empirical study of how method, class and package identifier names evolve to better understand the motives of their evolution. The empirical validation involves a set of 524,113 rename refactorings, performed on 3,795 Java systems. In a nutshell, our findings demonstrate that most rename refactorings narrow the meaning of the identifiers for which they are applied. Further, we analyze commit messages to contextualize these renames.","PeriodicalId":404412,"journal":{"name":"Proceedings of the 2nd International Workshop on Refactoring","volume":"172 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126209073","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}
