Flask-SocketIO VS asynction

Hi! I'm trying to write test cases for Flask socket io using pytest. But it seems we can't test the emitted messages from namespaces using pytest only. What would be a good approach to test it? Also, I am trying to figure out resources for flask socketio testing, I tried writing tests using some repos but there's not much explanation on what is being done. So it would be really helpful if anyone could point me towards any resources. These are the repos I was talking about 1. https://github.com/miguelgrinberg/Flask-SocketIO/blob/main/test_socketio.py 2. https://github.com/julianYaman/bitcoinPriceApp_python/tree/master

WS-Emit is based on Flask-SocketIO and sending message is as simple as in any other flask-socketio application:

https://github.com/miguelgrinberg/Flask-SocketIO might help you.

The framework is driven by the AsyncAPI specification, built on top of Flask-SocketIO. and inspired by Connexion.

I don't know what module you're using for websockets, but looking at an issue posted on one of them, the thread should periodically sleep in order for I/O to function properly.

I'm running a Flask server on my local machine and am using it to pull data from a serial port and display it in real time on a webpage with Flask-socketio. I followed the example here and am encountering an interesting behavior. I was able to replicate the results of the example, but when I alter the background_thread function to include reading and parsing data from the serial port, something seems to be blocking the socket from sending the data. My code correctly establishes a socket and opens the connection, and can even emit messages correctly at the beginning of the thread function, but once it hits a time.sleep(5), emitting doesn't work anymore. Here's the original thread function that works (and includes a time.sleep()!):

I have Flask application with SocketIO integration.Current user flow seems like 

I think you're having this issue. https://github.com/miguelgrinberg/Flask-SocketIO/issues/1570

Check Miguel's flask-socketio examples.

The purpose of Asynction is to empower a specification first approach when developing SocketIO APIs in Python. It guarantees that your API will work in accordance with its documentation.
