Testing Services

[George Maggessy]

Hi Gurus,

I'm a total newbie on AngularJs and my question is certainly simple. I'm trying to test a service that has a decorated $log as a parameter. What would be the right approach? Mock the $log.getInstance() function or inject the decorated implementation into the test?

define(['angular'], function(angular) {

   'use strict';

   angular.module('myApp.services.MyApi', [])

      .factory('MyApi', function($q, $log) {

            $log = $log.getInstance('VimApi');

            init = function() {

                ...

            };

         // Public API

         return {

            init: init

         };

      });

});

define(['angular', 'angular-mocks', 'app'], function(angular, mocks, app) {

   'use strict';

   describe('Service: myApi', function () {

      var myApi;

      beforeEach(function() {

         //Mock getInstance?

         module('myApp.services.MyApi');

         inject(function ($log, _MyApi_) {

            myApi = _MyApi_;

         });

      });

      it('should initialize', function () {

         expect(!!myApi).toBe(true);

      });

   });

});

Any help is appreciated.

Cheers,

George

Hi Garry,

Thanks for your help.

I added the basicService example to my project just for sanity check and it worked. 

However, I'm using a decorated $log. That is, I need not only to inject $log, but also augment its methods.

For instance, I have a getInstance function on $log, which I'm injecting on my tests using the code below.

beforeEach(function() {

         module('esxUiApp.services.VimApi', function($provide) {

            var MockLog = {

               getInstance: jasmine.createSpy('getInstance')

            };

            $provide.value('$log', MockLog);

         });

      });

And as you can imagine, tests fail when it finds any other native method on $log, such as debug().

I also thought about mocking the whole $log object, but I'd like to see the logs in my test output.

Any ideas?

Cheers,

George 

Best,
