title: Can not Inject Service into Controller
body: <p>I wrote a service (empty, just for testing purposes), which I want to inject into a controller.</p>
  
  <p>However, this is unfortunately not working, I can't see the Problem.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>app.controller('AppCtrl', function($scope, $location, Test){
  
    $scope.goto = function(destination){
      $location.path(destination);
    }
  
  })
  
  app.service('Test', ['', function(){
  
  }])
  </code></pre>
  
  <p>And here is the Exception:</p>
  
  <pre><code>Error: [$injector:unpr] Unknown provider: Provider &lt;-  &lt;- Test
  http://errors.angularjs.org/1.3.13/$injector/unpr?p0=Provider%20%3C-%20%20%3C-%20Test
