From e16d19fd3bbe90103502dd7db8008ea139a49f6a Mon Sep 17 00:00:00 2001 From: SAM Date: Wed, 8 Jul 2026 04:21:05 +0000 Subject: [PATCH] feat: validate Supabase RLS policies with pgTAP and JS tests (#546) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Replace migration 004 with a full pgTAP suite (28 SQL tests) covering: own-data access, cross-operator SELECT/INSERT/UPDATE/DELETE isolation on cooperatives / meters / readings / certificates, admin bypass, unauthenticated denial, readings-via-meter-join scoping, and certificate retirement visibility. - Add supabase/tests/rls_policies.sql — standalone pgTAP file (28 tests) wrapped in a BEGIN/ROLLBACK transaction so it is safe to run on any database independently of the migration process. - Add apps/web/src/__tests__/rls.test.ts — JS/TS integration harness (32 tests across 7 describe blocks) using a mocked Supabase client; runs in CI without a live database. - Update supabase/migrations/rollbacks/20240101000004_rls_tests.down.sql to delete all pgTAP fixture rows in dependency order. - Update .github/workflows/supabase.yml to run `supabase db test` after `supabase db reset`, so pgTAP failures block CI.
