de Vries, Chiel (author)To validate the quality of software, test cases are used. These test cases are often manually-written, which is labor-intensive. To avoid this problem, automated software testing was invented. Search-based software testing is a useful tool for developers to automatically generate test cases. However, improvements are still needed to create test...bachelor thesis 2020

Datskiv, Sergey (author)On the intuitive level, software testing is important because it assures the quality of the software used by humans. However, ensuring this quality is not an easy task because as the complexity of the software increases, so do the efforts to test it. Search-based software testing is an active research field that develops and explores tools for...bachelor thesis 2023

de Munck, Philip (author)As software and systems continue to get more complex, software testing is an important field to ensure that software functions properly. Every day information about software testing is being discussed on the internet via blog posts, discussion boards, and more. This information is scattered among many different websites, making it hard to access...bachelor thesis 2023

Dimitrov, Stoyan (author)To ensure that a software system operates in the correct way, it is crucial to test it extensively. Manual software testing is severely time-consuming, and developers often underestimate its importance. Consequently, many tools for automatic test generation have been developed during the past decade. EvoSuite is a state-of-the-art tool for...bachelor thesis 2022

Nijkamp, Nienke (author)TestCube amplifies existing unit tests and creates a new test suite with additional coverage for the source code. The names automatically generated by TestCube do not give any information on the behaviour or the coverage improvement of the amplified test case. In this paper, we present an approach to naming these amplified test cases by...bachelor thesis 2021

Gökmen, Onur (author)Software testing plays a crucial role in delivering reliable software. Currently, research is ongoing on how software developers and testers acquire this knowledge of software testing to deliver reliable software and what kind of knowledge is being transferred to developers and testers. In an effort to gain more insight into this area, we will...bachelor thesis 2023

Özmetin, Doruk (author)In this study, we try to understand what kind of topics and frameworks are covered by the popular software testing books, and see whether these topics satisfy the industry needs and address the rising trends. To define "popular" software testing books, we formulated three heuristics. The topics of the books are analyzed through LDA topic...bachelor thesis 2023

van den Berg, Bo (author)Big data applications are becoming increasingly popular. The importance of testing these applications increases with it. A recently proposed work called BigFuzz applies automated testing. The big data fuzzing tool shows very promising results. The aim of this research is to inspect how coverage guidance affects the performance of big data...bachelor thesis 2021

Džiugaitė, Neda (author)Software testing is a necessary aspect of software development. With high expectations placed on software testers and a shortage of qualified professionals, Massive Open Online Courses (MOOCs) have emerged as a potential solution to improve software testing education. MOOCs provide accessible education and can offer a comprehensive review of...bachelor thesis 2023

Li, Erwin (author)Software testing is an important but time-consuming task, making automatic test case generation an appealing solution. The current state-of-the-art algorithm for test case generation is DynaMOSA, which is an improvement of NSGA-II that applies domain knowledge to make it more suitable for test case generation. Although these enhancements are...bachelor thesis 2023

Viero, Diego (author)In recent decades, automatic test generation has advanced significantly, providing developers with time-saving benefits and facilitating software debugging. While most research in this field focused on search-based test generation tools for statically-typed languages, only a few have been adapted for dynamically-typed languages. The larger...bachelor thesis 2023

Spadini, D. (author), Schvarcbacher, Martin (author), Oprescu, Ana (author), Bruntink, Magiel (author), Bacchelli, A. (author)Test smells are poor design decisions implemented in test code, which can have an impact on the effectiveness and maintainability of unit tests. Even though test smell detection tools exist, how to rank the severity of the detected smells is an open research topic. In this work, we aim at investigating the severity rating for four test smells...conference paper 2020

van Meerten, M.C. (author), Kulahcioglu Ozkan, Burcu (author), Panichella, A. (author)Blockchain systems are prone to concurrency bugs due to the nondeterminism in the delivery order of messages between the distributed nodes. These bugs are hard to detect since they can only be triggered by a specific order or timing of concurrent events in the execution. <br/>Systematic concurrency testing techniques, which explore all possible...conference paper 2023

Panichella, A. (author), Liem, C.C.S. (author)Mutation testing is a well-established technique for assessing a test suite’s quality by injecting artificial faults into production code. In recent years, mutation testing has been extended to machine learning (ML) systems, and deep learning (DL) in particular; researchers have proposed approaches, tools, and statistically sound heuristics to...conference paper 2021

Oosterwaal, Sebastiaan (author), van Deursen, A. (author), De Souza Coelho, R. (author), Sawant, A.A. (author), Bacchelli, A. (author)One of the tasks of reviewers is to verify that code modifications are well tested. However, current tools offer little support in understanding precisely how changes to the code relate to changes to the tests. In particular, it is hard to see whether (modified) test code covers the changed code. To mitigate this problem, we developed OPERIAS...conference paper 2016

Olsthoorn, Mitchell (author), Derakhshanfar, P. (author), Panichella, A. (author)State-of-the-art search-based approaches for test case generation work at test case level, where tests are represented as sequences of statements. These approaches make use of genetic operators (i.e., mutation and crossover) that create test variants by adding, altering, and removing statements from existing tests. While this encoding schema has...conference paper 2021
