I have a problem on how to use jasmine spy objects to test controllers that
depends on a service and I have been tussling with this issue for some time
now as I am quite new to AngularJS based developments. Could you please
suggest what changes should be made in order to implement this test
correctly?
In this controller I am trying to test the user login process and it calls
loginRequest method in WebService to send out user credentials as a login
message. A loginreply message is received by the controller.If login
process is successful a URL redirection should happen.I have used jasmine
spy objects to mock the WebService functionality.
I have tried to use jasmine spy objects to mock the WebService
functionality but I seem to be doing something wrong which I have been
unable to pinpoint.But I am currently having a problem evaluating the
received message status and evaluating the URL redirection process based on
that.
*AngularJS code*
———————
Apps.controller(‘loginCtrl’,['$scope','$location','WebService','$timeout',,'$log','$http',
function($scope,$location,WebService,$timeout,$log,$http)
{
//Hardcoded values for testing
$scope.username = '[email protected]';
$scope.password = 'viranga123';
$scope.login = function()
{
var login = {};
login.UserName = $scope.username;
login.Password = $scope.password;
WebService.loginRequest($location.host(),$location.port(),"Check","'?'",login);//
}
//Error in Unit testing this block
$scope.$on('LSuccess_msg',function(e,msg)
{
if(angular.equals(msg.Status,"LOGIN_SUCCESS"))
{
$timeout(function ()
{
window.location.href = "http://"+<--custom redirection URL is added here-->;},
10);
}
});
}]);
*Unit test used to test controller*
—————————————-
“use strict”;
describe(“Controller : Login controller”, function()
{
var $scope, ctrl, $location, $timeout, WebServiceMock;
beforeEach(module(‘Apps’, function($provide)
{
WebServiceMock = jasmine.createSpyObj(“WebService”, ["loginRequest"]);
WebServiceMock.loginRequest.andReturn({ UserID:’1′, SessionId:’1118430′,
Status:’LOGIN_SUCCESS’, EMail:’[email protected]’, FirstName:’Viranga’});
$provide.value(“WebServiceMock”, WebServiceMock)
}));
beforeEach(inject(function($rootScope, $controller, $q, _$timeout_,
_$location_, _WebServiceMock_)
{
$scope = $rootScope.$new();
$timeout = _$timeout_;
$location = _$location_;
ctrl = $controller(‘loginCtrl’,{
$scope: $scope,
$location: $location,
WebService: _WebServiceMock_,
$timeout: $timeout
});
$scope.$digest();
}));
it(‘should call loginRequest WebServiceMock’, function ()
{
$scope.username = ‘[email protected]’;
$scope.password = ‘viranga123′;
$scope.$digest();
$scope.login();
expect(WebServiceMock.loginRequest).toHaveBeenCalled();
//Validate recieved data
spyOn($scope, ‘$on’).andCallThrough();
expect(result.Status).toEqual(“LOGIN_SUCCESS”);//Error here
});
});
*Error*

Chrome 36.0.1985 (Windows 7) Controller : Login controller should call is
loginRequest on WebService FAILED
TypeError: Cannot read property ‘Status’ of undefined at null.
Could you please suggest what changes should be made in order to implement
this test correctly ?
