"""
Tests for utils.plugin_utils.get_sync_hub_node_name().

Regression coverage: server/plugin.py used filename.split(".")[2] to tag
plugin objects received from a sync node, but by the time the hub processes
them decode_and_rename_files() has renamed the file to
last_result.<PREFIX>.decoded.<NodeName>.<N>.log - so index 2 is the literal
"decoded", and every synced plugin object (e.g. a WIFICANARY detection from a
WiFi satellite) was stored with syncHubNodeName = "decoded" instead of the
node's name.

Run from inside the NetAlertX container (utils.plugin_utils imports conf,
logger and helper):

    pytest "test/server/test_sync_hub_node_name.py" -v
