From 430c8ee7f817eacc422682150d6afc24338c099e Mon Sep 17 00:00:00 2001 From: kevin-asprec Date: Thu, 5 Mar 2026 17:44:19 +0800 Subject: [PATCH] test(05-04): add comprehensive API RBAC integration tests - 43 tests covering authentication (401), authorization (403), and tenant isolation - withPermission HOF returns 401 for unauthenticated, 403 for unauthorized - withPortalAuth returns 401/403 for non-portal users - All 5 roles (ADMIN, OFFICE_STAFF, COLLECTOR, TECHNICIAN, CLIENT) tested against all subjects - COLLECTOR cannot access billing/reports/subscriber management writes - TECHNICIAN cannot access payment/invoice/report endpoints - CLIENT can only read own data, create tickets - Two-tenant isolation: subscribers, invoices, payments invisible across tenants - Cross-tenant ID lookup returns null (no data leakage) - INFRA-03 satisfied Co-Authored-By: Claude Opus 4.6 --- .../__tests__/integration/api-rbac.test.ts | 851 ++++++++++++++++++ 1 file changed, 851 insertions(+) create mode 100644 src/lib/__tests__/integration/api-rbac.test.ts diff --git a/src/lib/__tests__/integration/api-rbac.test.ts b/src/lib/__tests__/integration/api-rbac.test.ts new file mode 100644 index 0000000..0d494dd --- /dev/null +++ b/src/lib/__tests__/integration/api-rbac.test.ts @@ -0,0 +1,851 @@ +/** + * API RBAC Integration Tests + * + * Comprehensive integration tests verifying API-layer authorization enforcement + * across all endpoints.
