Test Socket.IO Using a Node.js Client
You do not always need a browser to test Socket.IO.
The socket.io-client package can also be used from Node.js scripts.
Install it as a development dependency:
npm install -D socket.io-client
Create a test script to connect to your server, emit an event, receive a response, and disconnect.
This approach is useful for automated testing and backend integration tests.
