title: angularjs access form in jasmine without using $scope
body: <p>I want to test my form in angular, just like <a href="https://stackoverflow.com/questions/25022663/how-to-unit-test-angular-form/25024441#25024441">this solution from here</a>.  But in my case, I'm using <code>controllerAs</code> (I'm using controller without $scope to reference controller methods) syntax for my controller.</p>
  
  <p>How can I accomplish that? </p>
