A Guided Genetic Algorithm for Automated Crash Reproduction

To reduce the effort developers have to make for crash debugging, researchers have proposed several solutions for automatic failure reproduction. Recent advances proposed the use of symbolic execution, mutation analysis, and directed model checking as underling techniques for post-failure analysis of crash stack traces. However, existing...

Beyond Unit-Testing in Search-based Test Case Generation: Challenges and Opportunities

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...

Multi-objective Black-box Test Case Prioritization based on Wordnet Distances

Test case prioritization techniques have emerged as effective strategies to optimize this process and mitigate the regression testing costs. Commonly, black-box heuristics guide optimal test ordering, leveraging information retrieval (e.g., cosine distance) to measure the test case distance and sort them accordingly. However, a challenge...
