mock_client.update_one = AsyncMock(return_value=AsyncMock(matched_count=1, modified_count=1)). Outcome: Here the minimal code to make your example works.

FIXED_BYSolution

using `magicmock` to mock it could lead to unusual or unexpected behavior when checking for call counts — Since `get_item` might be an asynchronous function in your middleware. Tension: using `magicmock` to mock it could lead to unusual or unexpected behavior. Outcome: which is designed to work with async functions.

FIXED_BYSolution

call_count is 0. Tension: This generates an error indicating that call_count is 0. Outcome: Check for `await_count` instead of `call_count`.
