+"""
+Auth-flow integration tests for genenetwork3 protected endpoints.
+
+Tests that GN3's `@require_token` decorator correctly rejects requests
+that carry no bearer token or a malformed/invalid token.  These tests do
+not require database state — the rejection happens before any DB access.
+
+Endpoints under test are in `gn3/api/case_attributes.py`:
+
+    POST /api/case-attribute/<inbredset_id>/edit
+    POST /api/case-attribute/<inbredset_id>/approve/<change_id>
+    POST /api/case-attribute/<inbredset_id>/reject/<change_id>
+
+Via the nginx proxy the external URL prefix is `/api3/`, so the full CD
+URL for the first endpoint is:
+
+    https://cd.genenetwork.org/api3/case-attribute/1/edit
+
+Run with:
+
+    pytest -m "gn3 and auth_flow"
