socket.io-mock

socket.io-mock

A mock to test the socket.io library implementation.

This is an enhanced copy of socket-io-mock.

I made this project becuase socket-io-mock does not appear to be actively maintained. This project takes advantage of eventemitter covering more of the socket.io-client library. If you see any bugs or lack of support for socket.io features, please drop an issue.

Installation

npm install socket.io-mock

Usage

Simply create new socket mock with:

import MockedSocket from 'socket.io-mock';
let socket = new MockedSocket();

And use the socket as if it was a normal Socket.io socket.

For example:

import SocketMock from 'socket.io-mock';
import { should } from 'chai';

describe('Fast and isolated socket tests', function(){
    it('Sockets should be able to talk to each other without a server', function(done) {
        let socket = new SocketMock();

        socket.on('message', function (message) {
            message.should.be.equal('Hello World!');
        });
        socket.socketClient.emit('message', 'Hello World!');
    });
});
