GNNs can exhibit incorrect behavior, resulting in severe consequences. Therefore, testing is necessary and pivotal. However, labeling all test inputs for GNNs can be prohibitively costly and time-consuming, especially when dealing with large and complex graphs. In response to these challenges, test selection has emerged as a strategic approach to alleviate labeling expenses. The objective of test selection is to select a subset of tests from the complete test set. While various test selection techniques have been proposed for traditional deep neural networks (DNNs), their adaptation to GNNs presents unique challenges due to the distinctions between DNN and GNN test data. Specifically, DNN test inputs are independent of each other, whereas GNN test inputs (nodes) exhibit intricate interdependencies. Therefore, it remains unclear whether DNN test selection approaches can perform effectively on GNNs. To fill the gap, we conduct an empirical study that systematically evaluates the effectiveness of various test selection methods in the context of GNNs, focusing on three critical aspects: <b>1) Misclassification detection</b>: selecting test inputs that are more likely to be misclassified; <b>2) Accuracy estimation</b>: selecting a small set of tests to precisely estimate the accuracy of the whole testing set; <b>3) Performance enhancement</b>: selecting retraining inputs to improve the GNN accuracy. Our empirical study encompasses 7 graph datasets and 8 GNN models, evaluating 22 test selection approaches. Our study includes not only node classification datasets but also graph classification datasets. Our findings reveal that: 1) In GNN misclassification detection, confidence-based test selection methods, which perform well in DNNs, do not demonstrate the same level of effectiveness; 2) In terms of GNN accuracy estimation, clustering-based methods, while consistently performing better than random selection, provide only slight improvements; 3) Regarding selecting inputs for GNN performance improvement, test selection methods, such as confidence-based and clustering-based test selection methods, demonstrate only slight effectiveness; 4) Concerning performance enhancement, node importance-based test selection methods are not suitable, and in many cases, they even perform worse than random selection.</p>","PeriodicalId":11525,"journal":{"name":"Empirical Software Engineering","volume":"92 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141739972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, in comparison to images or text, labelling video test cases for the purpose of assessing system accuracy can lead to increased expenses due to their temporal structure and larger volume. Test prioritization has emerged as a promising approach to mitigate the labeling cost, which prioritizes potentially misclassified test inputs so that such inputs can be identified earlier with limited time and manual labeling efforts. However, applying existing prioritization techniques to video test cases faces certain limitations: they do not account for the unique temporal information present in video data. Unlike static image datasets that only contain spatial information, video inputs consist of multiple frames that capture the dynamic changes of objects over time. In this paper, we propose VRank, the first test prioritization approach designed specifically for video test inputs. The fundamental idea behind VRank is that video-type tests with a higher probability of being misclassified by the evaluated DNN classifier are considered more likely to reveal faults and will be prioritized higher. To this end, we train a ranking model with the aim of predicting the probability of a given test input being misclassified by a DNN classifier. This prediction relies on four types of generated features: temporal features (TF), video embedding features (EF), prediction features (PF), and uncertainty features (UF). We rank all test inputs in the target test set based on their misclassification probabilities. Videos with a higher likelihood of being misclassified will be prioritized higher. We conducted an empirical evaluation to assess the performance of VRank, involving 120 subjects with both natural and noisy datasets. The experimental results reveal VRank outperforms all compared test prioritization methods, with an average improvement of 5.76%<span>(sim )</span>46.51% on natural datasets and 4.26%<span>(sim )</span>53.56% on noisy datasets.</p>","PeriodicalId":11525,"journal":{"name":"Empirical Software Engineering","volume":"45 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141739839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to a variety of build scheduling and test selection heuristics studied in the past, new artifact-based build technologies like Bazel have built-in support for advanced performance optimizations such as parallel build and incremental build (caching of build results). However, little is known about the extent to which new build technologies like Bazel deliver on their promised benefits, especially for long-build duration projects. In this study, we collected 383 Bazel projects from GitHub, then studied their parallel and incremental build usage of Bazel in popular CI services (GitHub Actions, CircleCI, Travis CI, or Buildkite), and compared the results with Maven projects. We conducted 3,500 experiments on 383 Bazel projects and analyzed the build logs of a subset of 70 buildable projects to evaluate the performance impact of Bazel’s parallel builds. Additionally, we performed 102,232 experiments on the 70 buildable projects’ last 100 commits to evaluate Bazel’s incremental build performance. Our results show that 31.23% of Bazel projects adopt a CI service but do not use Bazel in the CI service, while for those who do use Bazel in CI, 27.76% of them use other tools to facilitate Bazel’s execution. Compared to sequential builds, the median speedups for long-build duration projects are 2.00x, 3.84x, 7.36x, and 12.80x, at parallelism degrees 2, 4, 8, and 16, respectively, even though, compared to a clean build, applying incremental build achieves a median speedup of 4.22x (with a build system tool-independent CI cache) and 4.71x (with a build system tool-specific cache) for long-build duration projects.

Typical examples of such systems are plugin-based systems, microservices, and modular software systems. Such types of software systems have several advantages motivating a large body of research to propose approaches for the migration from monolithic software systems to modular architecture (mainly microservices). However, a few prior works investigated how to assist practitioners post-migration. In fact, these studies reported that having independent components is difficult to achieve, leading to several evolution challenges that are still manually handled. In this paper, we conduct an empirical study on OpenStack and its 1,310 projects (aka., components) to better understand how the changes to a given component depend on changes of other components (aka., cross-component changes) so managers can better plan for their changes in a cross-component project, and researchers can design better solutions to help practitioners in such a co-evolution and the maintenance of multi-component software systems. We observe that the concept of ownership exists in the context of OpenStack, as different teams do not share the responsibility over the studied components of OpenStack. Despite that, dependencies across different components are not exceptional but exist in all releases. In fact, we observe that 52,069 OpenStack changes (almost 10% of all the changes) depend on changes in other components. Such a number of cross-component changes continuously increased over different years and releases, up to a certain release in which OpenStack decided to make a major refactoring of its project by archiving over 500 projects. We also found that a good percentage of cross-component changes (20.85%) end up being abandoned, leading to wasteful synchronization efforts between different teams. These dependent changes occur for different reasons that we qualitatively identified, among which configuration-related (34.64%) changes are the most common, while developers create cross-component changes for testing purposes then abandon such changes as the most prevalent category (38.45%). These cross-project changes lead to collaboration between different teams to synchronize their changes since 24.55% of the pairs of two cross-component changes are made by different developers, while the second change is reviewed by the developer of the first change of the pair (71.63%). Even when a developer makes both changes, that developer ends up working on a project that she/he is less familiar with. Our results shed light on how different components end up being dependent on each other in terms of their maintenance, which can help managers better plan their changes and guide researchers in proposing appropriate approaches for assisting in the maintenance of multi-component systems.</p>","PeriodicalId":11525,"journal":{"name":"Empirical Software Engineering","volume":"93 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141613761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A Dockerfile contains the requirements to build a Docker image containing a target application. There are several best practice rules for writing Dockerfiles, but the developers do not always follow them. Violations of such practices, known as Dockerfile smells, can negatively impact the reliability and performance of Docker images. Previous studies showed that Dockerfile smells are widely diffused, and there is a lack of automatic tools that support developers in fixing them. However, it is still unclear what Dockerfile smells get fixed by developers and to what extent developers would be willing to fix smells in the first place. The aim of our study is twofold. First, we want to understand what Dockerfiles smells receive more attention from developers, i.e., are fixed more frequently in the history of open-source projects. Second, we want to check if developers are willing to accept changes aimed at fixing Dockerfile smells (e.g., generated by an automated tool), to understand if they care about them. We evaluated the survivability of Dockerfile smells from a total of 53,456 unique Dockerfiles, where we manually validated a large sample of smell-removing commits to understand (i) if developers performed the change with the intention of removing bad practices, and (ii) if they were aware of the removed smell. In the second part, we used a rule-based tool to automatically fix Dockerfile smells. Then, we proposed such fixes to developers via pull requests. Finally, we quantitatively and qualitatively evaluated the outcome after a monitoring period of more than 7 months. The results of our study showed that most developers pay more attention to changes aimed at improving the performance of Dockerfiles (image size and build time).

Studies on mono-language systems suggest that design smells may increase the risk of bugs and negatively impact software quality.

However, like traditional software, ML applications are not immune to the bugs that result from programming errors. Explicit programming errors usually manifest through error messages and stack traces. These stack traces describe the chain of function calls that lead to an anomalous situation, or exception. Indeed, these exceptions may cross the entire software stack (including applications and libraries). Thus, studying the ML-related patterns in stack traces can help practitioners and researchers understand the causes of exceptions in ML applications and the challenges faced by ML developers. To that end, we mine Stack Overflow (SO) and study 18, 538 ML-related stack traces related to seven popular Python ML libraries. First, we observe that ML questions that contain stack traces are less likely to get accepted answers than questions that don’t, even though they gain more attention (i.e., more views and comments). Second, we observe that recurrent patterns exist in ML stack traces, even across different ML libraries, with a small portion of patterns covering many stack traces. Third, we derive five high-level categories and 26 low-level types from the stack trace patterns: most patterns are related to <i>model training</i>, <i>python basic syntax</i>, <i>parallelization</i>, <i>subprocess invocation</i>, and <i>external module execution</i>. Furthermore, the patterns related to external dependencies (e.g., file operations) or manipulations of artifacts (e.g., model conversion) are among the least likely to get accepted answers on SO. Our findings provide insights for researchers, ML library developers, and technical forum moderators to better support ML developers in writing error-free ML code. For example, future research can leverage the common patterns of stack traces to help ML developers locate solutions to problems similar to theirs or to identify experts who have experience solving similar patterns of problems. Researchers and ML library developers could prioritize efforts to help ML developers identify misuses of ML APIs, mismatches in data formats, and potential data/resource contentions so that ML developers can better avoid/fix model-related exception patterns, data-related exception patterns, and multi-process-related exception patterns, respectively.</p>","PeriodicalId":11525,"journal":{"name":"Empirical Software Engineering","volume":"1 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141550953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The four dimensions of RN-related issues revealed by the taxonomy and the corresponding strategies from the framework include: 1) <i>Content</i> (419, 25.47%): RN producers tend to overlook information rather than include inaccurate details, especially for breaking changes. To address this, effective completeness validations are recommended, such as managing Pull Requests, issues, and commits related to RNs; 2) <i>Presentation</i> (150, 9.12%): inadequate layout may bury important information and lead to end users’ confusion, which can be mitigated by employing a hierarchical structure, standardized format, rendering RNs, and folding techniques; 3) <i>Accessibility</i> (303, 18.42%): many users find RNs inaccessible due to link deterioration, insufficient notification, and obfuscated RN locations.
