primus-sinon-chai
Provides additional assertions and stubs I use while testing realtime applications built on Primus
Works in the browser and node.js
For browser use, it expects you to have already loaded underscore (or lodash?), sinon, chai, sinon-chai
Usage
nodejs setup
npm install --save-dev primus-sinon-chai
var psc = require('primus-sinon-chai');
global.expect = psc.chai.expect;
global.sinon = psc.sinon;
global.sparkStub = psc.spark;browser setup
bower install --save-dev primus-sinon-chai
