Building Scalable Apps with Redis and Node.js

Setting up tests

So far, we have not done any testing. This is bad and not a best practice. We will rectify this here. We will only build a few tests, but it will demonstrate how to create tests. Create a directory named tests and create the routes.js file.

Open the file and paste the following code:

var routes = require('../routes'),
  config = require('../config'),
  nodeunit = require('nodeunit'),
  Request = require('./request'),
  Response = require('./response');

exports.indexRouteTest = function(test){
  var res = new Response();
  test.equal(res.view, undefined);
  routes.index({}, res);
  test.equal(res.view, 'index');
  test.equal(res.viewData.title, 'Index');
  test.done();
};

Here, we are testing the index route. It should call render on the response object ...
