Oosterbroek, W. (author), Brandt, C.E. (author), Zaidman, A.E. (author)Test amplification generates new tests by modifying existing, manually written tests.<br/>Up until now, this process preserves statements that were relevant for the original test case but are no longer needed for the behavior of the new test case.<br/>These unnecessary statements impact the readability of the tests in question.<br/>As a part of...conference paper 2021

Nijkamp, N. (author), Brandt, C.E. (author), Zaidman, A.E. (author)Test amplification generates new test cases that improve the coverage of an existing test suite. To convince developers to integrate these new test cases into their test suite, it is crucial to convey the behavior and the improvement in coverage that the amplified test case provides. In this paper, we present NATIC, an approach to generate names...conference paper 2021

Beller, M. (author), Bholanath, R. (author), McIntosh, S. (author), Zaidman, A.E. (author)The use of automatic static analysis has been a software engineering best practice for decades. However, we still do not know a lot about its use in real-world software projects: How prevalent is the use of Automated Static Analysis Tools (ASATs) such as FindBugs and JSHint? How do developers use these tools, and how does their use evolve over...conference paper 2016

Beller, M. (author), Levaja, I. (author), Panichella, A. (author), Gousios, G. (author), Zaidman, A.E. (author)As software engineering researchers, we are also zealous tool smiths. Building a research prototype is often a daunting task, let alone building an industry-grade family of tools supporting multiple platforms to ensure the generalizability of results. In this paper, we give advice to academic and industrial tool smiths on how to design and build...conference paper 2016

Panichella, S. (author), Panichella, A. (author), Beller, M. (author), Zaidman, A.E. (author), Gall, H. (author)Automated test generation tools have been widely investigated with the goal of reducing the cost of testing activities. However, generated tests have been shown not to help developers in detecting and finding more bugs even though they reach higher structural coverage compared to manual testing. The main reason is that generated tests are...report 2015

Beller, M. (author), Gousios, G. (author), Panichella, A. (author), Zaidman, A.E. (author)The research community in Software Engineering and Software Testing in particular builds many of its contributions on a set of mutually shared expectations. Despite the fact that they form the basis of many publications as well as open-source and commercial testing applications, these common expectations and beliefs are rarely ever questioned....conference paper 2015

Chen, C. (author), Gross, H.G. (author), Zaidman, A.E. (author)Due to their loosely coupled and highly dynamic nature, service-oriented systems offer many benefits for realizing fault tolerance and supporting trustworthy computing. They enable automatic system reconfiguration when a faulty service is detected. Spectrum-based fault localization (SFL) is a statistics-based diagnosis technique that can be...journal article 2015

Beller, M. (author), Zaidman, A.E. (author), Karpov, A. (author)Micro-clones are tiny duplicated pieces of code; they typically comprise only a few statements or lines. In this paper, we expose the “last line effect,” the phenomenon that the last line or statement in a micro-clone is much more likely to contain an error than the previous lines or statements. We do this by analyzing 208 open source projects...conference paper 2015

Beller, M. (author), Gousios, G. (author), Zaidman, A.E. (author)What do we know about software testing in the real world? It seems we know from Fred Brooks’ seminal work “The Mythical Man-Month” that 50% of project effort is spent on testing. However, due to the enormous advances in software engineering in the past 40 years, the question stands: Is this observation still true? In fact, was it ever true? The...conference paper 2015

Espinha, T. (author), Zaidman, A. (author), Gross, H.G. (author)Web APIs provide a systematic and extensible approach for application-toapplication interaction. Developers using web APIs are forced to accompany the API providers in their software evolution tasks. In order to understand the distress caused by this imposition on web API client developers we perform a semi-structured interview with six such...report 2014

This work focuses on the role of the integrator and investigates working habits and challenges alike. We set up an exploratory qualitative study involving a large-scale survey involving 749 integrators, to which we add quantitative...report 2014

Bezemer, C.P. (author), Milon, E. (author), Zaidman, A. (author), Pouwelse, J. (author)Regression testing can be done by re-executing a test suite on different software versions and comparing the outcome. For functional testing, the outcome of such tests is either pass (correct behaviour) or fail (incorrect behaviour). For non-functional testing, such as performance testing, this is more challenging as correct and incorrect are...report 2014

Athanasiou, D. (author), Nugroho, A. (author), Visser, J. (author), Zaidman, A. (author)Automated testing is a basic principle of agile development. Its benefits include early defect detection, defect cause localization and removal of fear to apply changes to the code. Therefore, maintaining high quality test code is essential. This study introduces a model that assesses test code quality by combining source code metrics that...report 2014

Beller, M. (author), Bacchelli, A. (author), Zaidman, A.E. (author), Juergens, E. (author)Code review is the manual assessment of source code by humans, mainly intended to identify defects and quality problems. Modern Code Review (MCR), a lightweight variant of the code inspections investigated since the 1970s, prevails today both in industry and open-source software (OSS) systems. The objective of this paper is to increase our...conference paper 2014

Heck, P. (author), Zaidman, A. (author)Verification activities are necessary to ensure that the requirements are specified in a correct way. However, until now requirements verification research has focused on traditional up-front requirements.

Bezemer, C.P. (author), Zaidman, A. (author)Preprint submitted to Elsevier. The goal of performance maintenance is to improve the performance of a software system after delivery. As the performance of a system is often characterized by unexpected combinations of metric values, manual analysis of performance is hard in complex systems. In this paper, we propose an approach that helps...report 2013

Luijten, B. (author), Visser, J. (author), Zaidman, A. (author)We mined the issue database of GNOME to assess how issues are handled. How many issues are submitted and resolved? Does the backlog grow or decrease? How fast are issues resolved? Does issue resolution speed increase or decrease over time? In which subproject are issues handled most efficiently? To answer such questions, we apply several...report 2013
