Angular.js promise not resolving when unit testing service with karma

Question

I am trying to unit test an Angular.js service, and need to set an expect on a promise returned from a Mock service (using Jasmine). I am using the karma unit testing framew

Answer 1

Assuming that you are using ngFacebook/ngModule a quick note before the solution/ideas is that this project does not have unit tests ! Are you sure you want to use this project ?

I did a quick scan of your Unit Tests on Github and found following missing:-

1) Module initialization. ngFacebook needs that or you need to initialize your module that does the same thing.

beforeEach(module('ngFacebook'));

OR

beforeEach(module('yieldtome'));

2) Seriously consider mocking ngFacebook module

At unit level tests you are testing your code within a mocked bubble where outside interfaces are stubbed out.

Otherwise) Try adding calling the API as below:-

 $rootScope.$apply(function() {
     this.FacebookService.getFacebookToken().then(function(){
        //your expect code here
     });
    });
 $httpBackend.flush();//mock any anticipated outgoing requests as per [$httpBackend][2]
