+"""
+Test script for control_server.py UI WebSocket API.
+
+Starts a client to localhost:8765 and sends a small sequence of UI commands:
+- pattern_change
+- color_change
+- brightness_change
+- parameter_change (n1/n2/n3)
+
+Usage examples:
+  python test/test_control_server.py --pattern on --r 255 --g 0 --b 0 --brightness 150 --n1 5 --n2 5 --n3 1
+  python test/test_control_server.py --pattern rainbow
