Obtaining such control flow graphs is relevant in the industrial setting of legacy modernisation, to quickly demonstrate to code owners that modernisation engineers did not break their business logic. They need to be convinced that a migration did not affect the flow around critical parts of their code such as database accesses. Focusing on the control flow around embedded SQL queries and confirming that the code logic has been preserved improves customers' trust and satisfaction in the modernisation. Our proposed algorithm and approach uses fuzzy parsing as opposed to full parsing to parse mainly the control flow constructs, while delegating the full parsing of embedded languages like SQL to an external parser, and produces a control flow graph directly while skipping over most of the input in linear time. Such a fuzzy parser is easier to construct and adapt to particular languages and needs than a full parser with a visitor to elicit control flow. Comparisons are made of the fuzzy parser to an industrial-strength full parser.","PeriodicalId":300084,"journal":{"name":"2022 IEEE International Conference on Software Maintenance and Evolution (ICSME)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122327177","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, in practice, passing tests heavily outnumber failing tests regarding a fault, leading to failing tests being a minority class in contrast to passing tests. Previous work has empirically shown that the lack of failing tests regarding a fault leads to a class-balanced test suite, which tends to hamper fault localization effectiveness.To address this issue, we propose MSGen: a Model-domain Synthesized Failing Test Generation approach. MSGen utilizes the widely used information model of fault localization (i.e., an abstraction of the execution information and test results of a test suite), and uses the minimum variability of the minority feature space to create new synthesized model-domain failing test samples (i.e., synthesized vectors with failing labels defined as the information model) for fault localization. In contrast to traditional test generation directly from the input domain, MSGen seeks to synthesize failing test samples from the model domain. We apply MSGen to 12 state-of-the-art localization approaches and also compare MSGen to 2 representative data optimization approaches. The experimental results show that our synthesized test generation approach significantly improves fault localization effectiveness with up to 51.22%.","PeriodicalId":300084,"journal":{"name":"2022 IEEE International Conference on Software Maintenance and Evolution (ICSME)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128052381","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}

Writing test cases for complicated business scenarios with multiple and ordered API calls is also a heavy task that requires a lot of human effort. In this paper, we present the design and deployment of SIT, a fully automated server interface reliability testing platform at ByteDance that provides capabilities including (1) traffic data generation based on combinatorial testing and fuzzing, (2) scenario testing for complicated business logics and (3) automated test execution with fault localisation in a controlled environment that does not affect online services.

The emergence of conflicts among stakeholders may lead to undesired effects on software maintainability, yet it is often unavoidable in the long run. Community smells, i.e., sub-optimal communication and collaboration practices, have been defined to map recurrent conflicts among developers. While some community smell detection tools have been proposed in the recent past, these can be mainly used for research purposes because of their limited level of usability and user engagement. To facilitate a wider use of community smell-related information by practitioners, we present CADOCS, a client-server conversational agent that builds on top of a previous community smell detection tool proposed by Almarini et al. to (1) make it usable within a well-established communication channel like Slack and (2) augment it by providing initial support to software analytics instruments useful to diagnose and refactor community smells.

Recent research has proposed random, search-based and model-based testing techniques for GUI event generation. In industrial practices, different companies have developed various GUI exploration tools such as Facebook Sapienz, WeChat WeTest and ByteDance Fastbot to test their products. However, these tools are bound to their predefined GUI exploration strategies and lack of the ability to generate human-like actions to test meaningful scenarios. To address these challenges, Humanoid is the first Android testing tool that utilises deep learning to imitate human behaviours and achieves promising results over current model-based methods. However, we find some challenges when applying Humanoid to test our sophisticated commercial apps such as infinite loops and low test coverage. To this end, we performed the first case study on the performance of deep learning techniques using commercial apps to understand the underlying reason of the current weakness of this promising method. Based on our findings, we propose MUBot (Multi-modal User Bot) for human-like Android testing. Our empirical evaluation reveals that MUBot has better performance over Humanoid and Fastbot, our in-house testing tool on coverage achieved and bug-fixing rate on commercial apps.","PeriodicalId":300084,"journal":{"name":"2022 IEEE International Conference on Software Maintenance and Evolution (ICSME)","volume":"34 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116616894","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}

Recent studies on DL-APR techniques have focused on the training phase to generate more accurate patches; however, a trained model cannot always generate an accurate patch for every new defect code, as the training dataset does not completely represent the new defects to be input in the future. DL-APR researchers should study a method to elicit the best performance on new inputs from the trained and deployed model. A new defect instance (i.e., defect codes and their context codes) is one of the crucial input data that determine the accuracy of the DL-APR, which can be changed and improved. We improve the quality of new input defect instances by focusing on the presence of noise tokens which compromise the defect instances’ quality, thus impairing the accuracy of generated patches. This paper shows that 1) there are noise tokens which prevent correct patch generation (inference) in a new defect instance, and 2) it is necessary to mask these noise tokens to avoid their usage in inferencing patch codes. In order to validate these two assertions, we use a state-of-the-art DL-APR technique and a genetic algorithm to generate near-optimal defect instances which maximize the patch generation accuracy (i.e., the BLEU score) of 4,573 defect instances. Based on optimization results, we found that 1) noise tokens impair patch generation accuracy in approximately 49% of instances, and 2) if these tokens are precluded from inference by masking them, we can improve patch generation accuracy by 88%. The results suggest that future work is required to automatically remove noise tokens from new defect instances so that the trained patch generator generates better patches.","PeriodicalId":300084,"journal":{"name":"2022 IEEE International Conference on Software Maintenance and Evolution (ICSME)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114734165","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}

We do, however, not know how well these results translate to iOS.This research project aims to close this gap by analysing iOS applications with regards to maintainability and security. Regarding maintainability, we analyse code smells in iOS applications, the evolution of code smells in iOS applications and compare code smell distributions in iOS and Android applications. Regarding security, we analyse the evolution of the third-party library dependency network for the iOS ecosystem. Additionally, we analyse how publicly reported vulnerabilities spread in the library dependency network.Regarding maintainability, we found that the distributions of code smells in iOS and Android applications differ. Code smells in iOS applications tend to correspond to smaller classes, such as Lazy Class. Regarding security, we found that the library dependency network of the iOS ecosystem is not growing as fast as in some other ecosystems. There are less dependencies on average than for example in the npm ecosystem and, therefore, vulnerabilities do not spread as far.","PeriodicalId":300084,"journal":{"name":"2022 IEEE International Conference on Software Maintenance and Evolution (ICSME)","volume":"241 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115196407","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}

To remove this design flaw, several Move Method refactoring tools have been proposed. To the best of our knowledge, state-of-the-art related techniques can be broadly divided into two categories: the first line is non-machine-learning-based approaches built on software measurement, while the selection and thresholds of software metrics heavily rely on expert knowledge. The second line is machine learning-based approaches, which suggest Move Method refactoring by learning to extract features from code information. However, most approaches in this line treat different forms of code information identically, disregarding their significant variation on data analysis. In this paper, we propose an approach to recommend Move Method refactoring named RMove by automatically learning structural and semantic representation from code fragment respectively. We concatenate these representations together and further train the machine learning classifiers to guide the movement of method to suitable classes. We evaluate our approach on two publicly available datasets.

However, such capability can be subject to illness or even unexpected crash, when contexts, for suffering environmental noises, become inaccurate or even conflict with each other. Fortunately, various constraint checking techniques have been proposed to validate contexts against consistency constraints, in order to guard context consistency for applications in a timely manner. However, with the growth of environmental dynamics and context volume, it is getting more and more challenging to check context consistency in time. In this paper, we propose a novel approach, INFuse, to soundly fuse together two lines of techniques, namely, incremental checking and concurrent checking, for efficient constraint checking. Realizing such check fusion has to address the challenges rising from the gap between the micro analysis for reusable elements in incremental checking and the macro collection of parallel tasks in concurrent checking. INFuse solves the challenges by automatically deciding maximal concurrent boundaries for context changes under checking (i.e., what-correctness problem), and soundly fusing incremental and concurrent checking for context consistency (i.e., how-correctness problem), with theoretical guarantees. Our experimental evaluation with real-world data shows that INFuse could improve constraint checking efficiency by 18.6x–171.1x, as compared with existing state-of-the-art techniques.","PeriodicalId":300084,"journal":{"name":"2022 IEEE International Conference on Software Maintenance and Evolution (ICSME)","volume":"509 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133532003","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}
