I’m trying to apply unit testing to my function onPersistSuccess, but this error appears

Typeerror: Undefined is not an Object (evaluating 'self.data.ID')

I have tried to define it in several ways but the error persists. I would like to know what the interference of this in calling this in test cases and how I can solve.

Below follows my function and test iterations:

(function () {
'use strict';

angular.module('app')
    .service('BusinessLogicService', BusinessLogicService);

BusinessLogicService.$inject = ['$rootScope', '$state', '$stateParams', 'StcpUtilsService', 'StorageService', 'storage', 'LanguageResource'];

function BusinessLogicService($rootScope, $state, $stateParams, StcpUtilsService, StorageService, storage, LanguageResource) {

    var self = this;
    var t = LanguageResource.t;
    var _storage = StorageService[storage];

    self.data = null;
    self.form = null;
    self.paramsRedirect = null;
    self.redirect = null;
    self.refresh = null;
    self.user_id = null;
    self.instance_id = null;

I’m applying the test as follows:

describe('Testing BusinessLogicService', function () {
beforeEach(module('app'));

var rootScope, state, stateParams, StcpUtilsService, StorageService, storage, language, httpBackend; 
var srv; 

describe('Testing BusinessLogicService', function () {
beforeEach(module('app'));

var rootScope, state, stateParams, StcpUtilsService, StorageService, storage, language, httpBackend; 
var srv; 

beforeEach(inject(function (BusinessLogicService, $rootScope, $state, $stateParams, StcpUtilsService, StorageService, storage, LanguageResource, $httpBackend) {        
    rootScope = $rootScope;
    srv = BusinessLogicService;
    state = $state;
    stateParams = $stateParams;
    StcpUtilsService = StcpUtilsService; 
    StorageService =StorageService; 
    storage = storage;
    language = LanguageResource; 
    httpBackend = $httpBackend;  

    var fakeRequest = function(){
        return;
    }; 

    httpBackend = $httpBackend;
    httpBackend.when('GET', './configs/config.json').respond(fakeRequest);
    httpBackend.when('GET', './configs/modules.json').respond(fakeRequest);
    httpBackend.when('GET', './configs/app_ver').respond(fakeRequest);
    httpBackend.when('GET', './configs/trans_tab.json').respond(fakeRequest);
    httpBackend.when('GET', './json/pt-br.json').respond(fakeRequest);
    httpBackend.when('GET', './json/es.json').respond(fakeRequest);
    httpBackend.when('GET', './json/en-gb.json').respond(fakeRequest);

    // var self = this;          


})); 

it('testing function onPersistSuccess', function(){
    self = {
        data:{
            ID: 0
        }
    }
    srv.onPersistSuccess();
});


})

In your code you have $emit(), however none $on() is set -where, I imagine, the payload containing the property ID:'' would be applied to the scope. As it stands, your Undefined occurs because self.data is not populated.

@Onosendai self = this, how this interferes with my test. How this is influencing this function?

this, in the context mentioned, is the internal scope of the function BusinessLogicService() - something completely other than $scope and $rootScope. self.data, its return, does not receive at any time the payload used in $emit().

@Onosendai I took the rootScope. $Mit and keeps giving the same error.
