"""
Endpoint tests for the plugin-registry routes in api_v3:
POST /plugins/store/refresh and POST /plugins/registry-from-url.

Both reach out to the network through PluginStoreManager (mocked here) and
had no endpoint-level coverage; registry-from-url in particular takes a
user-supplied URL and hands it straight to the manager.
