-"""Smoke test for the WebSocket transport.

-Runs the full WS stack end-to-end over a real TCP connection, covering both
-``src/mcp/client/websocket.py`` and ``src/mcp/server/websocket.py``. MCP
-semantics (error propagation, timeouts, etc.) are transport-agnostic and are
-covered in ``tests/client/test_client.py`` and ``tests/issues/test_88_random_error.py``.
