Much previous work implicitly assumed it to be sufficient to re-compute mutant suites per release. Sadly, this makes mutation results inconsistent; mutant scores from each release cannot be directly compared, making it harder to measure test improvement. Furthermore, regular code change means that a mutant suite's relevance will naturally degrade over time. We measure this degradation in relevance for 143,500 mutants in 4 non-trivial systems finding that, on overage, 52% degrad","authors_text":"Mark Harman, Mike Papadakis, Milos Ojdanic","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"cs.SE","submitted_at":"2022-12-22T14:53:45Z","title":"Keeping Mutation Test Suites Consistent and Relevant with Long-Standing Mutants"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2212.11762","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:8e8454553063126e595bedac048351843e4f39b866148c3eb296124abde1cdc7","target":"record","created_at":"2026-07-05T05:27:42Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"c09258e1aea442c2639bda24e68a70584e5cda3ff020d5aa2a1ec3037261aa7c","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"cs.SE","submitted_at":"2022-12-22T14:53:45Z","title_canon_sha256":"4b296e81019f01d3fb90e75aee883613e71f9820584a8d03fe5e1bdef145fa44"},"schema_version":"1.0","source":{"id":"2212.11762","kind":"arxiv","version":1}},"canonical_sha256":"0b7b8f72d79d7e3db1828d69644cedcec9635cebe1fa8e95ca3a1738f12fd6ec","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0b7b8f72d79d7e3db1828d69644cedcec9635cebe1fa8e95ca3a1738f12fd6ec","first_computed_at":"2026-07-05T05:27:42.670472Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:27:42.670472Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"DPIG/nWJ3noeZoL12PZ8kaTAbaLqxK8N4Ii4kNK9I1HWJJuca3URMx8bNtFaAY4hqo84yn83FElStJc2zsiACQ==","signature_status":"signed_v1","signed_at":"2026-07-05T05:27:42.670852Z","signed_message":"canonical_sha256_bytes"},"source_id":"2212.11762","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8e8454553063126e595bedac048351843e4f39b866148c3eb296124abde1cdc7","sha256:0a47262c86a762b7872fd1fe89f1a6909957be0645841cd888e67ca007861849"],"state_sha256":"759e417da9bfadf5f270c151c6738fcb330bd500efa6721f4eb560ff4eaf56b0"}
