Optimizing regression testing is important. Test parallelization has the potential to leverage the power of multi-core architectures to accelerate regression testing. Unfortunately, it is not possible to directly use parallelization options available in build systems and testing frameworks without introducing test flakiness. Tests can fail because of data races or broken test dependencies. Although it is possible to safely circumvent those problems with the assistance of an automated tool to collect test dependencies (e.g., PRADET), the cost of that solution is prohibitive, defeating the purpose of test parallelization. This paper proposes PASTE an approach to automatically parallelize the execution of test suites. PASTE alternates parallel and sequential execution of test cases and test classes to circumvent provoked test failures. PASTE does not provide the safety guarantee that flakiness will not be manifested, but our results indicate that the strategy is sufficient to avoid them. We evaluated PASTE on 25 projects mined from GitHub using an objective selection criteria. Results show that (i) PASTE could circumvent flakiness introduced with parallelization in all projects that manifested them and (ii) 52% of the projects benefited from test-parallelization with a median speedup of 1.59x (best: 2.28x, average: 1.47x, worst: 0.93x).","PeriodicalId":205629,"journal":{"name":"2021 IEEE International Conference on Software Maintenance and Evolution (ICSME)","volume":"180 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131886518","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}

Research has proposed several language-agnostic reduction techniques that automatically reduce bug-inducing programs in arbitrary programming languages, but there is no large-scale, conclusive evaluation of these algorithms yet. Furthermore, the development of new algorithms is hampered by the unavailability of comparable implementations of previous techniques and of diverse test programs that trigger different bugs in real compilers. To close these gaps and to foster future research in this area, this paper makes three contributions: (1) A framework that includes efficient, fine-tuned implementations of 6 state-of-the-art reducers, (2) a diverse benchmark that comprises 321 fuzzer-generated programs in two programming languages that trigger 110 different bugs in real compilers, and (3) a comparative study that builds upon our framework and benchmark and compares the reduction techniques w.r.t. their effectiveness and efficiency. Our results show that there is no reduction technique yet that performs best across all test cases and languages. Our framework and benchmark are available online and we provide the necessary scripts and tools to replicate our study.","PeriodicalId":205629,"journal":{"name":"2021 IEEE International Conference on Software Maintenance and Evolution (ICSME)","volume":"29 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130259169","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 effectiveness of CI/CD may depend on the extent to which such pipelines are properly maintained to cope with the system and its underlying technology evolution, as well as to limit bad practices. This paper reports the results of a study combining a qualitative and quantitative evaluation on CI/CD pipeline restructuring actions. First, by manually analyzing and coding 615 pipeline configuration change commits, we have crafted a taxonomy of 34 CI/CD pipeline restructuring actions, either improving extra-functional properties or changing the pipeline's behavior. Based on such actions, we have developed a metric extractor for Travis-CI pipelines, which extracts 16 indicators of how a pipeline evolves. The analysis of the pipeline evolution for 4,644 projects using Travis-CI and developed in 8 programming languages shows how some pipeline components, such as jobs and steps tend to change more often than others, but also the Docker adoption by the projects increases over time.","PeriodicalId":205629,"journal":{"name":"2021 IEEE International Conference on Software Maintenance and Evolution (ICSME)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133984531","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, due to the limited availability of public COBOL resources, entry-level developers, who assume the mantle of legacy COBOL systems maintainers, face significant difficulties during routine maintenance tasks, such as code comprehension and defect location. While we made substantial advances in the field of software maintenance for modern programming languages yearly, mainframe maintenance has received limited attention. With this study, we aim to direct the attention of researchers and practitioners towards investigating and addressing challenges associated with mainframe development. Specifically, we explore the scope of defects affecting COBOL systems and defect location strategies commonly followed by COBOL developers and compare them with the modern programming language counterparts. To this end, we surveyed 30 COBOL and 74 modern Programming Language (PL) developers to understand the differences in defects and defect location strategies employed by the two groups. Our preliminary results show that: (1) major defect categories affecting the COBOL ecosystem are different than defects encountered in modern PL software projects; (2) the most challenging defect types in COBOL are also the ones that occur most frequently; and (3) COBOL and modern PL developers follow similar strategies to locate defective code.","PeriodicalId":205629,"journal":{"name":"2021 IEEE International Conference on Software Maintenance and Evolution (ICSME)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115870691","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, semi-structured and unstructured software artifacts have been leveraged by researchers to build recommender systems aimed at supporting developers in different tasks, such as transforming user feedback in maintenance and evolution tasks, suggesting experts, or generating software documentation. More specifically, Natural Language (NL) parsing techniques have been successfully leveraged to automatically identify (or extract) the relevant information embedded in unstructured software artifacts. However, such techniques require the manual identification of patterns to be used for classification purposes. To reduce such a manual effort, we propose an NL parsing-based tool for software artifacts analysis named NEON that can automate the mining of such rules, minimizing the manual effort of developers and researchers. Through a small study involving human subjects with NL processing and parsing expertise, we assess the performance of NEON in identifying rules useful to classify app reviews for software maintenance purposes. Our results show that more than one-third of the rules inferred by NEON are relevant for the proposed task.

Coverage is typically computed on source code, by assessing the extent of source code entities (e.g., statements, data dependencies, control dependencies) that are exercised when running test cases. When considering REST APIs, an alternative perspective to assess test suite completeness is with respect to the service definition. This paper presents Restats, a test coverage tool for REST APIs that supports eight state-of-the-art test coverage metrics with a black-box perspective, i.e., only relying on the OpenAPI interface specification of the REST API under test. In fact, metrics are computed by only observing the HTTP requests and responses occurring at testing time, and no access to source/compiled code of the REST API is required. These coverage metrics come in handy for: (i) developers and test engineers working at development and maintenance tasks; (ii) stakeholders and customers who want to evaluate the completeness of acceptance tests; (iii) researches interested in comparing different automated test case generation strategies.
