Test cases stop being hand-written one by one: five agents split the work and audit themselves, averaging a 93.4% mutation score across five datasets
Software test-case design has long depended on manual work, and models that treat generation as one-shot text translation struggle with multi-layered business rules. A pipeline of five roles, parser, triage, architect, writer and auditor, turns test generation into a stateful reasoning process in which the auditor corrects scripts before output. Across five datasets spanning travel, telecom, financial regulation and a government job platform, the pipeline averaged a 93.4% mutation score, 1.4% hallucination and 7.8% redundancy, at an average generation time of 21.2 hours.
