To generate tests, Ultimate TestGenencodes test goals as property violations and generates test cases from counterexamples detected by trace abstraction.For Test-Comp\u00a02026, we keep this general principle but make two changes.First, we adapt Ultimate TestGento a recent parallelization of trace abstraction.Second, we extend Ultimate TestGenwith a Path-Checker, which runs in parallel with parallel trace abstraction and exhaustively explores counterexamples but skips refinement.<\/jats:p>","DOI":"10.1007\/978-3-032-22774-4_28","type":"book-chapter","created":{"date-parts":[[2026,4,16]],"date-time":"2026-04-16T09:18:30Z","timestamp":1776331110000},"page":"492-496","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Ultimate TestGen: Combining Parallel Trace Abstraction and Symbolic Path Execution (Competition Contribution)"],"prefix":"10.1007","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-7716-3898","authenticated-orcid":false,"given":"Max","family":"Barth","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8947-5373","authenticated-orcid":false,"given":"Daniel","family":"Dietsch","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4252-3558","authenticated-orcid":false,"given":"Matthias","family":"Heizmann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5890-4673","authenticated-orcid":false,"given":"Marie-Christine","family":"Jakobs","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,4,17]]},"reference":[{"key":"28_CR1","doi-asserted-by":"publisher","unstructured":"Barth, M., Dietsch, D., Heizmann, M., Jakobs, M.C.: Ultimate Paralizer: Parallel\ntrace abstraction (competition contribution).
