title: Angular2 unit testing with karma and angular-cli do not work
body: <p>I just build an application with the official angular-cli on ubuntu 14.04 with nam version v2.14.12 and node version v4.2.6 and karma version v0.13.19,</p>
  
  <p>I did steps below:</p>
  
  <pre><code>sudo ng new Project
  cd Project
  ng serve
  </code></pre>
  
  <p>The project is working, I have project Works! on localhost:4200</p>
  
  <pre><code>ng build
  </code></pre>
  
  <p>Built project successfully. Stored in "dist/"</p>
  
  <pre><code>cd dist
  </code></pre>
  
  <p>I am now in the building project folder</p>
  
  <pre><code>karma start
  </code></pre>
  
  <p>I just have a confirmation message that says:
      Karma v0.13.19 server started at <a href="http://localhost:9876/" rel="nofollow">http://localhost:9876/</a></p>
  
  <p>What I did wrong? Why no unit testings appear?</p>
  
  <p>Thanks :)</p>
