From ed4d4e46408693e360441722c5a515d22f99d8c7 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Hartmut=20N=C3=B6renberg?= Date: Thu, 2 Apr 2026 23:31:26 +0200 Subject: [PATCH] test(api): fill router auth and security coverage gaps MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Four new test files — 27 tests total: - role-router-auth.test.ts (8): UNAUTHORIZED/FORBIDDEN on all mutations for unauthenticated/USER callers; MANAGER and ADMIN happy paths - webhook-router-auth.test.ts (6): adminProcedure guard verified for all six webhook procedures across USER/MANAGER/ADMIN roles - comment-sanitization-router.test.ts (4): proves stripHtml runs before db.comment.create — script tags stripped, plain text and @mentions preserved - auth-anomaly-check/route.test.ts (+5 unit tests): detectAuthAnomalies() unit coverage — empty window, global threshold, per-entity threshold, null entityId, and both anomaly types firing simultaneously Co-Authored-By: claude-flow --- .../api/cron/auth-anomaly-check/route.test.ts | 104 +++++++++ .../comment-sanitization-router.test.ts | 145 +++++++++++++ .../src/__tests__/role-router-auth.test.ts | 204 ++++++++++++++++++ .../src/__tests__/webhook-router-auth.test.ts | 163 ++++++++++++++ 4 files changed, 616 insertions(+) create mode 100644 packages/api/src/__tests__/comment-sanitization-router.test.ts create mode 100644 packages/api/src/__tests__/role-router-auth.test.ts create mode 100644 packages/api/src/__tests__/webhook-router-auth.test.ts diff --git a/apps/web/src/app/api/cron/auth-anomaly-check/route.test.ts b/apps/web/src/app/api/cron/auth-anomaly-check/route.test.ts index 650af55..327a4eb 100644 --- a/apps/web/src/app/api/cron/auth-anomaly-check/route.test.ts +++ b/apps/web/src/app/api/cron/auth-anomaly-check/route.test.ts @@ -203,3 +203,107 @@ describe("GET /api/cron/auth-anomaly-check — error handling", () => { expect(body.ok).toBe(false);
