How to manually trigger a net.socket error event during testing

Question

I wrote a TCP server using Node.js and on my tests (with Mocha) I'm testing that the server actually emits all the events it should. The one problem that I'm finding is that I cannot trigger the error event at will so I cannot automate this test.

    socket.on('error', function()
    {
        // How do I test this?
    });

Is there a way to trigger this event manually? O maybe craft a corrupt packet?

Answer 1

You can emit it manually: socket.emit('error', new Error('foo bar baz'));
