Asynchronous fixtures and test functions should use "asyncio.get_running_loop()" instead. warnings.warn( src/tests/test_integration.py::test_server_lifecycle /home/herman/Documents/vscode/iac-memory-mcp-server/.venv/lib/python3.13/site-packages/pytest_asyncio/plugin.py:867: DeprecationWarning: The event_loop fixture provided by pytest-asyncio has been redefined in /home/herman/Documents/vscode/iac-memory-mcp-server/src/tests/test_integration.py:14 Replacing the event_loop fixture with a custom implementation is deprecated and will lead to errors in the future. If you want to request an asyncio event loop with a scope other than function scope, use the "loop_scope" argument to the asyncio mark when marking the tests. If you want to return different types of event loops, use the event_loop_policy fixture. warnings.warn( -- Docs: https://docs.pytest.org/en/stable/how-to/capture-warnings.html =========================== short test summary info ============================ ERROR src/tests/test_integration.py::test_server_lifecycle - tests.test_utils.exceptions.MCPTestError: Session setup failed: Failed to establish MCP test context: unhandled errors in a TaskGroup (1 sub-exception) Operation: test Traceback (most recent call last): File "/home/herman/Documents/vscode/iac-memory-mcp-server/.venv/lib/python3.13/site-packages/mcp/client/stdio.py", line 149, in stdio_client process, ^^^^^^^ File "/home/herman/Documents/vscode/iac-memory-mcp-server/.venv/lib/python3.13/site-packages/anyio/abc/_resources.py", line 29, in __aexit__ await self.aclose() File "/home/herman/Documents/vscode/iac-memory-mcp-server/.venv/lib/python3.13/site-packages/anyio/_backends/_asyncio.py", line 1066, in aclose await self.wait() File "/home/herman/Documents/vscode/iac-memory-mcp-server/.venv/lib/python3.13/site-packages/anyio/_backends/_asyncio.py", line 1074, in wait return await self._process.wait() ^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.13/asyncio/subprocess.py", line 137, in wait return await self._transport._wait() ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3.13/asyncio/base_subprocess.py", line 248, in _wait return await waiter ^^^^^^^^^^^^ asyncio.exceptions.CancelledError: Cancelled by cancel scope 728f52a65160 During handling of the above exception, another exception occurred: + Exception Group Traceback (most recent call last): | File "/home/herman/Documents/vscode/iac-memory-mcp-server/src/tests/test_utils/mcp_utils.py", line 36, in mcp_test_context | async with stdio_client(server_params) as streams: | ~~~~~~~~~~~~^^^^^^^^^^^^^^^ | File "/usr/lib/python3.13/contextlib.py", line 235, in __aexit__ | await self.gen.athrow(value) | File "/home/herman/Documents/vscode/iac-memory-mcp-server/.venv/lib/python3.13/site-packages/mcp/client/stdio.py", line 148, in stdio_client | anyio.create_task_group() as tg, | ~~~~~~~~~~~~~~~~~~~~~~~^^ | File "/home/herman/Documents/vscode/iac-memory-mcp-server/.venv/lib/python3.13/site-packages/anyio/_backends/_asyncio.py", line 767, in __aexit__ | raise BaseExceptionGroup( | "unhandled errors in a TaskGroup", self._exceptions | ) | ExceptionGroup: unhandled errors in a TaskGroup (1 sub-exception) +-+---------------- 1 ---------------- | Traceback (most recent call last): | File "/home/herman/Documents/vscode/iac-memory-mcp-server/.venv/lib/python3.13/site-packages/mcp/client/stdio.py", line 124, in stdout_reader | await read_stream_writer.send(exc) | File "/home/herman/Documents/vscode/iac-memory-mcp-server/.venv/lib/python3.13/site-packages/anyio/streams/memory.py", line 255, in send | raise BrokenResourceError from None | anyio.BrokenResourceError +------------------------------------ The above exception was the direct cause of the following exception: Traceback (most recent call last): File "/home/herman/Documents/vscode/iac-memory-mcp-server/src/tests/test_integration.py", line 27, in mcp_session async with mcp_test_context( ~~~~~~~~~~~~~~~~^ operation_name="test", ^^^^^^^^^^^^^^^^^^^^^^ env={"PYTHONUNBUFFERED": "1", "MCP_DEBUG": "1"}, ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ) as session: ^ File "/usr/lib/python3.13/contextlib.py", line 214, in __aenter__ return await anext(self.gen) ^^^^^^^^^^^^^^^^^^^^^ File "/home/herman/Documents/vscode/iac-memory-mcp-server/src/tests/test_utils/mcp_utils.py", line 62, in mcp_test_context raise MCPTestError(error_msg) from e tests.test_utils.exceptions.MCPTestError: Failed to establish MCP test context: unhandled errors in a TaskGroup (1 sub-exception) Operation: test ======================== 2 warnings, 1 error in 30.10s =========================
