From f41ed2b1c0e37b31d37261e1099814a0a88d5087 Mon Sep 17 00:00:00 2001 From: Manas Srivastava Date: Wed, 20 May 2026 15:24:53 +0530 Subject: [PATCH] test(integration): rigorous-integration layer across 5 reliability tracks MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds the next layer up from existing unit tests + chaos drills: Track 1 — Backup/restore integration tests (api/e2e/, build tag integration_backup): - Wraps infra/scripts/restore-drill.sh in Go test scaffolding - Asserts RTO < 5min (postgres) / 3min (mongo), RPO < 30h - Asserts cleanup of throwaway namespace - Pure-parse tests for NR alert aggregation_window + Prom rule 36h/60h thresholds (run anywhere) - .github/workflows/integration-backup.yml: weekly cron + manual dispatch against KUBECONFIG_TEST_CLUSTER; defensive context-name gate to prevent prod runs Track 2 — Brevo webhook full pipeline (api/e2e/, e2e build tag): - Registry-iterating round-trip over every documented Brevo event: delivered/soft_bounce/hard_bounce/blocked/complaint/deferred/ unsubscribed/error - Idempotent re-delivery pins GREATEST(delivered_at) clause - Delivered-then-bounce pins makeClassUpdater contract (no time-travel) - Malformed payload 400 + unhandled event 200 end-to-end Track 3 — Propagation runner integration tests (worker/internal/jobs/, no build tag, runs under regular make gate): - Backoff exact-schedule via markRetry persistence for every position - Dead-letter at maxAttempts via markDeadLettered direct - F2 P1 guard: unknown_kind bounded retries - FOR UPDATE SKIP LOCKED concurrency (TEST_DATABASE_URL-gated) - Enum-vs-handler-map registry walk (TEST_DATABASE_URL-gated) Track 4 — Deep /readyz cross-service (api/e2e/, e2e build tag): - Envelope-shape walk across api/worker/provisioner - Brevo unreachable → 200 degraded (NOT 503) contract - Cache TTL: 50-burst latency assertion - Secret-leak scan (20+ hex chars regex) - P95 response time < 500ms - Criticality-matrix registry walk Track 5 — Cross-track contract test (api/e2e/, no build tag, runs under regular gate when TEST_DATABASE_URL is set): - Walks AuditKind* constants from api/internal/models/audit_kinds.go via source-file regex - Forward: every constant has a consumer spec entry - Reverse: every spec entry refers to a real constant - Emails=true implies Forwards=true (F4 ledger drift class) - Propagation kinds match pending_propagations.kind enum - Forwarder_sent.classification populated for rows > 5min old Companion: INTEGRATION-TESTS-2026-05-20.md (repo-root) lists every new test with the failure mode it catches, per CLAUDE.md rule 17 coverage-block discipline. Per CLAUDE.md rule 18 (registry-iterating regression tests, not hand-typed lists), every Track has at least one registry walk that fails LOUD on additions to the upstream registry without matching downstream wiring.
