Error in Unit testing help me to solve this

Question

I got an error in this test. Can anyone tell me why this happen?

describe('Controller: LoginCtrl', function () {
  beforeEach(function(){

    var $httpBackend;
    module("loginModule");
  });

  beforeEach(inject(function($controller, $rootScope, $location, $auth, $httpBackend) {
    this.$location= $location;
    this.$httpBackend=$httpBackend;
    this.scope= $rootscope.$new();
    this.redirect = spyOn($location,'path');

    $controller('LoginCtrl',{
        $scope: this.scope,
        $location: $location,
        auth: $auth

    });

  }));



  describe("succesfully loggin in",function(){
    it("should redirect you to home",function(){
        //arrange
        $httpBackend.expectPOST('/login',scope.login).respond(200);
        //act
        scope.login();
        $httpBackend.flush();

        //assertion
        expect(this.redirect).toHaveBeenCalledWith('/login');
    });

  });
});

The error I got is:

The error specifies that $auth is not available in the module. What are you trying to do with $auth in the controller? You might just be able to remove all references to it. — Peter Ashwell, Dec 29 '14 at 09:18

Angular provides automatic mocks for many things ($controller, $httpBackend) but not for $auth. You need to implement your own $authProvider (see https://docs.angularjs.org/guide/providers for a general overview) or mock $auth directly.

Use $provide to let Angular know about your new custom mock.
