From da306d46e6e173c2d0f8330e306c391585b444d5 Mon Sep 17 00:00:00 2001 From: shankar0123 Date: Thu, 30 Apr 2026 06:22:06 +0000 Subject: [PATCH] test(service): coverage uplift for production hardening II + adjacent helpers (R-CI-extended floor) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CI's R-CI-extended coverage gate failed on 2025-04-30: service-layer coverage was 68.7% vs the 70% floor. The drag was from new files (internal/service/ocsp_counters.go, ocsp_response_cache.go, export_audit_actions.go) that shipped without enough direct tests to keep the package above the floor. NEW internal/service/ocsp_counters_test.go (4 tests): - TestOCSPCounters_NewIsZero — fresh counter snapshot is all zero - TestOCSPCounters_EveryIncTicksItsLabel — table-driven test pinning every Inc* method to its label string + the no-cross- bleed invariant. Critical for Phase 8 Prometheus exposer contract: a typo in either side would silently drop the counter from /metrics/prometheus. - TestOCSPCounters_SnapshotIsCopy — mutating the returned map doesn't affect the underlying counters - TestOCSPCounters_ConcurrentTicksRace — race-detector smoke against sync/atomic primitives NEW internal/service/ocsp_response_cache_real_test.go (10 tests): - HappyPath_CachesAfterMiss — first fetch live-signs + writes cache row; second fetch hits cache - CacheWriteFailureIsNonFatal — putErrorRepo simulates disk full; response still returned (fail-soft contract) - StaleEntryRegenerates — entries with next_update in the past trigger re-sign on next fetch - InvalidateOnRevoke — pin the load-bearing security wire - InvalidateOnRevoke_DeleteFailureSurfacesError — error-path coverage for the delete branch - CountByIssuer + NilRepoReturnsEmpty - CAOperationsSvc.GetOCSPResponseWithNonce_CacheDispatchHit pins the nil-nonce → cache dispatch wire - CAOperationsSvc.GetOCSPResponseWithNonce_NonceBypassesCache pins the nonce-bearing → live-sign bypass wire (cache stays empty) - RevocationSvc.SetOCSPCacheInvalidator_WireConnects pins the setter through to the wired interface NEW internal/service/coverage_extras_test.go (~12 tests) targets the 0%-coverage chunks adjacent to the bundle's modified files so the package as a whole stays above the floor: - cert-export typed audit emission (Phase 7) round-trip with detail-map inspection (has_private_key + actor_kind + cipher pin) - PKCS12CipherModernAES256 pinned-value test (drift catches a future go-pkcs12 default change) - audit.ListAuditEvents + GetAuditEvent (handler-interface methods that were at 0%) - certificate.ListCertificatesWithFilter (M20 filter delegate) - discovery.{ListScans,GetScan,GetDiscoverySummary} (delegates) - health_check.{Update,SetNotificationService} delegates + audit - est.{deterministicSerial,zeroizeBytes,zeroizeKey} pure helpers + the live RSA + ECDSA key-zeroize branches Sandbox total: 67.6% → 69.9% (+2.3pp). The live keygen branches in zeroizeKey skip in the sandbox when crypto/rand isn't available but run on CI, so the CI total should land above the 70% floor with a small buffer.
