    .controller('ExampleController', ['$scope', Function ($scope) {
      $scope.salutation = 'Hello';
      $scope.name= 'World';
    }]);
</script>
<div ng-controller="ExampleController">
 Salutation: <input Type="text" ng-model="salutation"><br>
 Name: <input Type="text" ng-model="name"><br>
 <pre ng-bind-template="{{salutation}} {{name}}!"></pre>
</div>
protractor.js
it('should check ng-bind', Function() {
  var salutationElem = element(by.binding('salutation'));
  var salutationInput = element(by.model('salutation'));
  var nameInput = element(by.model('name'));

  expect(salutationElem.getText()).toBe('Hello World!');

  salutationInput.clear();
  salutationInput.sendKeys('Greetings');
  nameInput.clear();
  nameInput.sendKeys('user');

  expect(salutationElem.getText()).toBe('Greetings user!');});
