socket.io-mock

A mock to test the socket.io library implementation.

🚀 Now written in ES6! Bundled with rollup.

NEW! Added support for disconnect() and close()

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 { expect } 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) {
            expect(message).to.equal('Hello World!');
        });
        socket.socketClient.emit('message', 'Hello World!');
    });
});
