    assert not mocked_requests_get.called
```

In this example, we're using the `mocker` fixture to create a mock object for the `requests.get` function. We then set up the mock to return a response with a JSON payload containing the user's name. Finally, we test that our `fetch_user_name` function returns the expected result without actually making a network request.
