Researchers have recognized the negative impact of coincidental correctness, and the authors have previously conducted a study demonstrating its prevalence in test suites. However, that study was limited to system tests and small subjects seeded with artificial defects. In this paper, we conduct a wider scope study of CC that addresses the following research questions in the context of the Defects4J benchmark: RQ1: Is CC prevalent in Defects4J? RQ2: Is CC affected by the testing levels in Defects4J? RQ3: Do CC tests induce peculiar infection paths in Defects4J? RQ4: Are the infections likely to be nullified within or outside the buggy method? ....","url_abs":"http://arxiv.org/abs/1808.09233v4","url_pdf":"http://arxiv.org/pdf/1808.09233v4.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"links_only","authors_date_abstract":"arXiv metadata, CC0 1.0 (https://info.arxiv.org/help/license), from the Kaggle arXiv metadata snapshot of 2026-09-12"},"code_links":[{"paper_slug":"coincidental-correctness-in-the-defects4j","repo_url":"https://github.com/aub-software-testing/d4j_cc","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
