Testing functions inside controllers in angular

I am trying to test whether or not a particular function was called in my Angular controller. 

.controller('demo',function(){

  function init(){
     //some code..
  }

  init();
}

My test code looks something like below:

describe(..

  beforeEach(...
   function createController() { /*call this fn to create controller */
   )

  describe('controller initilization'.function(){
     var spy = spyOn(this,init)
     createController();  
     expect(spy).toHaveBeenCalled();
   }

)

ofcourse the above unit test fails. So how would i check if the function init() was called ?

The code you wrote isnt "spy-able". So either dont spy on init or only mock the controller collaborators.

You wrote the equivalent of a private method in Java.So make it public OR make the method belong to a collaborator.

move init into a service,pass the $scope as an argument if needed.

module.service('Init',function(){
    this.init=function($scope){};
})
.controller('Ctrl',function($scope,Init){
       Init.init($scope);
})

then 

$scope=$rootScope.new();
Init=$injector.get('Init');
spyOn(Init,'init');
Ctrl=$controller('Ctrl',{$scope:$scope});


expect(Init.init).toHaveBeenCalledWith($scope);
