How To Run the Unit Tests

pytest -v

asyncio notes

• Define coroutine prefixed "async"
• If a func (coroutine) behaviors like IO-block call (calls to remote, open file, sleep or queue operations), use it after "await" keyword.
• on "await", control returns to event loop to schedule other cooroutines. If available will be scheduled to run while blocking call is being waited.

Set up remote debug

• Create remote debug config in .vscode/launch.json (Shft+Ctl+P) | Debug: Add Configuration | Python Debugger
• Start the script from bash git:

python -m debugpy --listen 0.0.0.0:5678 --wait-for-client src/async_stream.py

• Debug view in Visual Studio Code. Select the "Python Debugger: Remote Attach" configuration. Click the green play button to start debugging.
