Dependency injection for Suman example

suman.ioc.js

//use your own version of this file at the root of your project to configure dependency injection


module.exports = (suman) => {  //load async deps for any of your suman tests

    suman.configure({

        'request': function () {
        
            //* but we could mock 'request' and reference that mock request somewhere in our project by returning the below
            // return require('./mock-request');
            return require('request');  //this is not very useful, but below we can see useful asynchronous loading of deps
        },
      
        'socketClient': function (cb) {

            const client = require('socket.io-client')('http://localhost:3000');
            client.on('connect', cb);
            client.on('error', cb);

        },

        'dbQueryAllUsers': (cb) => {

            var db = require('./db/postgres');

            db.sync().then(function () {
                return db.users.find();
            }).then(function (users) {
                cb(null, users);          //send 'users' as a value to any test that wants the value
            }).catch(function (err) {
