Nodejs, Express, Javascript Stack using Mocha and Chai Dependancies for TDD Testing

Using a nodejs, javascript and express stack I am testing out examples from the book "Web Development with Node and Express: Leveraging the Javascript Stack". I am currently running an example to preform Page Testing using mocha and chai. github link

Can someone explain where I will see the result of a test passing or failing? It could be possible the env is not set to development, and that could be anther reason for me not seeing changes during the test. I am not certain what I should be observing. For example, should there be output in the browser or the console? Below is the partial code I am implementing:

meadowlark.js

app.use( function( req, res, next){ 
     res.locals.showTests = app.get(' env') !== 'production' &&     
     req.query.test = = = '1'; next(); }); 

app.get('/ about', function( req, res) { 
       res.render(' about', { 
          fortune: fortune.getFortune(),
          pageTestScript: '/qa/tests-about.js' } ); });

// routes go here....

In the head:

<head> 
<title> Meadowlark Travel </ title > 
{{# if showTests}} 
     <link rel ="stylesheet" href ="/vendor/ mocha.css"> 
{{/ if}} 
<script src ="// code.jquery.com/ jquery-2.0.2. min.js" > </ script > 
</head >

In the body ......

{{# if showTests}} 
      < div id =" mocha" > </ div > 
      < script src ="/ vendor/ mocha.js" > </ script >
      < script src ="/ vendor/ chai.js" > </ script > 
      < script > 
           mocha.ui(' tdd'); 
           var assert = chai.assert; 
      </ script > 
      < script src ="/ qa/ tests-global.js" > </ script > 
      {{# if pageTestScript}} 
            < script src ="{{ pageTestScript}}" > </ script > 
      {{/ if}} 
      < script > mocha.run(); </ script > 
      {{/ if}} 
</ body >

qa/tests-global.js

suite(' Global Tests', function(){ 
    test(' page has a valid title', function(){ 
    assert(document.title && document.title.match(/\ S/) && 
           document.title.toUpperCase() != = 'TODO'); }); });

qa/tests-about.js

suite('" About" Page Tests', function(){ 
       test(' page should contain link to contact page', function(){ 
              assert( $(' a[ href ="/ contact"]'). length); }); });

To test this the instruction tell me the following: "Now, add test = 1 to the querystring (http:// localhost: 3000/? test = 1), and you’ll see the tests run on the page." I don't see any difference with ?test=1 added to the query string. Any help would be appreciated.

Update: Following the same app.use order as the author did within the meadowlark.js server I was able to successfully get the test displayed in the browser.
