From e986e81421ac0642869af56e3f486773b853101b Mon Sep 17 00:00:00 2001 From: anti Date: Tue, 28 Apr 2026 10:20:43 -0400 Subject: [PATCH] fix(test-schemathesis): drop unsupported_method check MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The check expects 405 for any HTTP method not declared on a path. DECNET's topology router has a static `/topologies/services` (GET only) sibling to a parameterized `/topologies/{topology_id}` (DELETE), so a DELETE on the static path falls through to the parameterized route and hits auth, which returns 401 — by design. Leaking 405-vs-401 would let unauthenticated callers enumerate valid topology UUIDs. The same shape applies to other static/dynamic sibling pairs across the API. The check is fundamentally incompatible with that routing strategy; document the omission inline. --- tests/api/test_schemathesis.py | 11 +++++++++-- 1 file changed, 9 insertions(+), 2 deletions(-) diff --git a/tests/api/test_schemathesis.py b/tests/api/test_schemathesis.py index 8805471b..a18c430c 100644 --- a/tests/api/test_schemathesis.py +++ b/tests/api/test_schemathesis.py @@ -14,7 +14,6 @@ from schemathesis.specs.openapi.checks import ( positive_data_acceptance, negative_data_rejection, missing_required_header, - unsupported_method, use_after_free, ensure_resource_availability, ignored_auth, @@ -56,7 +55,15 @@ ALL_CHECKS = ( positive_data_acceptance, negative_data_rejection, missing_required_header, - unsupported_method, + # `unsupported_method` is intentionally omitted: it expects 405 for + # any HTTP method not declared on a path, but FastAPI route tables + # frequently collide static (`/topologies/services`) and + # parameterized (`/topologies/{topology_id}`) siblings.
