(author), Pawełczak, Przemysław (author), Picek, S. (author), de Weerdt, M.M. (author), van Gemert, J.C. (author)We present ReproducedPapers.org : an open online repository for teaching and structuring machine learning reproducibility. We evaluate doing a reproduction project among students and the added value of an online reproduction repository among AI researchers. We use anonymous self-assessment surveys and obtained 144 responses. Results suggest...conference paper 2021

Panichella, A. (author), Panichella, Sebastiano (author), Fraser, Gordon (author), Sawant, Anand Ashok (author), Hellendoorn, Vincent J. (author)Test smells attempt to capture design issues in test code that reduce their maintainability. Previous work found such smells to be highly common in automatically generated test-cases, but based this result on specific static detection rules; although these are based on the original definition of “test smells”, a recent empirical study showed...conference paper 2020

Devroey, Xavier (author), Panichella, Sebastiano (author), Gambi, Alessio (author)We report on the results of the eighth edition of the Java unit testing tool competition. This year, two tools, EvoSuite and Randoop, were executed on a benchmark with (i) new classes under test, selected from open-source software projects, and (ii) the set of classes from one project considered in the previous edition. We relied on an updated...conference paper 2020

Derakhshanfar, P. (author), Devroey, Xavier (author), Zaidman, A.E. (author), van Deursen, A. (author), Panichella, A. (author)Evolutionary-based crash reproduction techniques aid developers in their debugging practices by generating a test case that reproduces a crash given its stack trace. In these techniques, the search process is typically guided by a single search objective called Crash Distance. Previous studies have shown that current approaches could only...conference paper 2020

Brandt, C.E. (author), Panichella, A. (author), Zaidman, A.E. (author), Beller, M.M. (author)Build logs are textual by-products that a software build process creates, often as part of its Continuous Integration (CI) pipeline. Build logs are a paramount source of information for developers when debugging into and understanding a build failure. Recently, attempts to partly automate this time-consuming, purely manual activity have come up,...conference paper 2020

Liem, C.C.S. (author), Panichella, A. (author)The rise in popularity of machine learning (ML), and deep learning in particular, has both led to optimism about achievements of artificial intelligence, as well as concerns about possible weaknesses and vulnerabilities of ML pipelines. Within the software engineering community, this has led to a considerable body of work on ML testing...conference paper 2020

Abdessalem, Raja Ben (author), Panichella, A. (author), Nejati, Shiva (author), Briand, Lionel (author), Stifter, Thomas (author)In the past years, several automated repair strategies have been proposed to fix bugs in individual software programs without any human intervention. There has been, however, little work on how automated repair techniques can resolve failures that arise at the system-level and are caused by undesired interactions among different system...conference paper 2020

Panichella, A. (author), Campos, José (author), Fraser, Gordon (author)EvoSuite is a search-based tool that automatically generates exe- cutable unit tests for Java code (JUnit tests). This paper summarizes the results and experiences of EvoSuite’s participation at the eighth unit testing competition at SBST 2020, where EvoSuite achieved the highest overall score (406.14 points) for the seventh time in eight...conference paper 2020

Derakhshanfar, P. (author), Devroey, Xavier (author), Panichella, A. (author), Zaidman, A.E. (author), van Deursen, A. (author)Approaches for automatic crash reproduction aim to generate test cases that reproduce crashes starting from the crash stack traces. These tests help developers during their debugging practices. One of the most promising techniques in this research field leverages search-based software testing techniques for generating crash reproducing test...conference paper 2020

Derakhshanfar, P. (author), Devroey, Xavier (author), Zaidman, A.E. (author), van Deursen, A. (author), Panichella, A. (author)Writing a test case reproducing a reported software crash is a common practice to identify the root cause of an anomaly in the software under test. However, this task is usually labor-intensive and time-taking. Hence, evolutionary intelligence approaches have been successfully applied to assist developers during debugging by generating a test...conference paper 2020

Olsthoorn, Mitchell (author), van Deursen, A. (author), Panichella, A. (author)Software testing is an important and time-consuming task that is often done manually. In the last decades, researchers have come up with techniques to generate input data (e.g., fuzzing) and automate the process of generating test cases (e.g., search-based testing). However, these techniques are known to have their own limitations: search-based...conference paper 2020

However, recent studies demonstrate that the readability of generated tests is very limited due to (i) uninformative identifiers and (ii) lack of proper documentation. Prior...conference paper 2020

Panichella, A. (author)Over the last decades, white-box search-based techniques have been applied to automate the design and the execution of test cases. While most of the research effort has been devoted to unit-level testing, integration-level test case generation requires to solve several open challenges, such as the combinatorial explosion of conditions or pre...conference paper 2019

Stallenberg, D.M. (author), Panichella, A.

The effectiveness of the protection mechanisms strongly depends on the quality of the sanitization and validation rule sets (e.g., regular expressions) and, therefore, security...conference paper 2019

Kechagia, M. (author), Devroey, Xavier (author), Panichella, A. (author), Gousios, G. (author), van Deursen, A. (author)Application Programming Interfaces (APIs) typically come with (implicit) usage constraints. The violations of these constraints (API misuses) can lead to software crashes. Even though there are several tools that can detect API misuses, most of them suffer from a very high rate of false positives. We introduce Catcher, a novel API misuse...conference paper 2019

Panichella, A. (author)Latent Dirichlet Allocation (LDA) has been used to support many software engineering tasks. Previous studies showed that default settings lead to sub-optimal topic modeling with a dramatic impact on the performance of such approaches in terms of precision and recall. For this reason, researchers used search algorithms (e.g., genetic...conference paper 2019

Panichella, A. (author), Kifetew, Fitsum Meshesha (author), Tonella, Paolo (author)Several criteria have been proposed over the years for measuring test suite adequacy. Each criterion can be converted into a specic objective function to optimize with search-based techniques in an attempt to generate test suites achieving the highest possible coverage for that criterion. Recent work has tried to optimize for multiple-criteria...conference paper 2018

Messaoudi, Salma (author), Panichella, A. (author), Bianculli, Domenico (author), Briand, Lionel (author), Sasnauskas, Raimondas (author)Many software engineering activities process the events contained in log files. However, before performing any processing activity, it is necessary to parse the entries in a log file, to retrieve the actual events recorded in the log. Each event is denoted by a log message, which is composed of a fixed part—called (event) template—that is the...conference paper 2018

Abdessalem, Raja Ben (author), Panichella, A. (author), Nejati, Shiva (author), Briand, Lionel C. (author), Stifter, Thomas (author)Complex systems such as autonomous cars are typically built as a composition of features that are independent units of functionality. Features tend to interact and impact one another’s behavior in unknown ways. A challenge is to detect and manage feature interactions, in particular, those that violate system requirements, hence leading to...conference paper 2018
