Test AngularJS factory function with Jasmine

Question

I am very new to this (angularjs, jasmine, testacular) and I have this code (I simplified it a bit, leaving only what matters):

//my_module.js
angular.module(\'m

You're not too far from what you need. First off, as you require my_data as my_module dependency, you don't need to inject my_module to the controller, just the factory (my_factory);

Secondly, you want to make use of ngMock. The docs are not very complete, but give a good insight. More here and a example here (look for test/unit/controllers).

Basically, what you want to do is to mock the service so you can be assured it has been called. To achieve it, inject $provide to your angular.mock.module call and provide a mocked my_factory service. The best way to achieve it is something like this:

describe('testing my_controller.my_function', function () {
  var mockedFactory, $rootScope, $controller;

  beforeEach(module('my_module', function($provide) {
    mockedFactory = {
      save: jasmine.createSpy()
    };

    $provide.value('my_factory', mockedFactory);
  }));

  beforeEach(inject(function(_$rootScope_, _$controller_) {
    $rootScope = _$rootScope_;
    $controller = _$controller_;
  }));

  scope = $rootScope.$new();

  it('should call the save function', function() {
    scope.my_function();
    expect(mockedFactory.save).toHaveBeenCalled();
  });
}

This way you'll override my_factory dependency.
