  <style type="text/css"> 
  .animate-show-hide.ng-hide {
    opacity: 0;
  }
  .animate-show-hide.ng-hide-add,
  .animate-show-hide.ng-hide-remove {
    transition: all linear 0.5s;
  }
  .check-element {
    border: 1px solid black;
    opacity: 1;
    padding: 10px;
  }
  </style>

  <script type="text/javascript">
  it('should check ngHide', function() {
  var checkbox = element(by.model('checked'));
  var checkElem = element(by.css('.check-element'));
  expect(checkElem.isDisplayed()).toBe(true);
  checkbox.click();
  expect(checkElem.isDisplayed()).toBe(false);
  });
  </script>
</head>
<body data-ng-controller="ProductController">

  <div class="col-md-8 col-sm-8 col-xs-8" style="position: absolute;top:0;bottom: 0;left: 0;right: 0;margin: auto;">

  <div class="panel panel-info spacer"><!-- <button type="button" class="close" data-dismiss="alert">x</button> -->
  <div class="panel-heading"><input type="checkbox" data-ng-model="checked" aria-label="Toggle ngHide"/><b> Product Form</b></div>
  <div class="panel-body">

   <div class="check-element animate-show-hide" data-ng-hide="checked">
   <form class="form-horizontal" name="prodForm" novalidate>
      <div class="form-group">
        .....
      </div>
        ....
   </form>
   </div>
   </div>
   </div>
   </div>

<script type="text/javascript" src="angular/angular.min.js"></script>
<script type="text/javascript" src="angular/angular-sanitize.min.js">   </script>
<script type="text/javascript" src="angular/angular-animate.js"></script>
</body>
</html>

此问题是您不创建module和controller。创建新文件并在其中发布此代码

(function() {
  angular.module('crm',[])
         .controller('ProductController', ProductController)

  ProductController.$inject = ['$scope'];
  function ProductController($scope) {

  }
})();

不要忘记注入html

<script src="script.js"></script>
