From 8c7f57d221b104d99b6c0e7cfc2d7d40817689aa Mon Sep 17 00:00:00 2001 From: Albert Mavashev Date: Wed, 13 May 2026 16:44:23 -0400 Subject: [PATCH] tests: live integration smoke tests for sync + async guards MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds `tests/integration/test_live_ap2_guard.py` — five tests (four sync + one async) exercising cycles_guard_payment and cycles_guard_payment_async end-to-end against a real Cycles server. Pattern mirrors cycles-client-python/tests/integration/ test_live_server.py: module-level `pytest.mark.skipif(not CYCLES_BASE_URL)` so the whole file is skipped at collection time when env vars are unset. Default `pytest` runs and CI ignore it; verified locally — 147 passed, 5 skipped. Why: every existing test uses MagicMock or AsyncMock for the CyclesClient surface. A server-side rename of a `Subject.dimensions` key, a field that flips from string to enum, or a change to how response.is_success classifies status codes — none of those would surface in mock-based tests. The integration suite catches that class of regression when run against a real dev server. Cost: zero in CI (skipped by env-var gate). When run, each test uses a fresh UUID-based transaction_id and a $0.00000001 (1 micro-cent) amount, so the suite is idempotent across runs and costs essentially nothing in budget per execution. Covers: - Sync clean commit (lifecycle + receipt fields) - Sync exception → release (no deadlock, propagates) - Sync dry-run → AP2DryRunResult with decision payload - Sync idempotent replay (same mandate → same reserve key, server collapses or surfaces finalized status — both OK) - Async clean commit with open_mandate_hash scope (exercises the AP2 §6 consume-once path through async) To run locally: CYCLES_BASE_URL=http://localhost:7878 \ CYCLES_API_KEY=cyc_dev_xxx \ CYCLES_TENANT=ap2-integration \ pytest tests/integration -v Tenant needs a budget with `payment.charge` permitted.
