Consider an application streaming a video over http/2. Perhaps the user pauses the video and the application stops reading bytes from this stream. The buffer will fill up, and flow control prevents the server from sending more data on this stream. When the user unpauses her video the buffer drains, the read is acknowledged, and the server proceeds to stream data.

## Dependencies with `yield` and `scope`

When using dependencies with `yield`, they can have a `scope` that defines when the exit code is run.

Use the default scope `"request"` to run the exit code after the response is sent back.

```python
from typing import Annotated

from fastapi import Depends, FastAPI

app = FastAPI()


def get_db():

        }

        // Test channel selection with mock request when no channels available
        ServerMessageBlock2Request mockRequest = mock(ServerMessageBlock2Request.class);
        when(mockRequest.getTreeId()).thenReturn(123);

        // Should throw NoAvailableChannelException when no healthy channels
