AngularJS Unit Tests: Injected Services undefined

Question

I have difficulties unit testing angularJS due to the injector not injecting properly. Anything I inject turns out to be undefined.

Module:

app.module.js

angular.module('myServices', []);

AngularTest.js

describe('AngularTest', function() {

    beforeEach(module('myServices'));

    var scope;

    beforeEach(inject(function(_$rootScope_) {
        // The injector unwraps the underscores (_) from around the parameter names when matching
        scope = _$rootScope_;

    }));

    describe('Testing Angular injection', function() {

      it('scope should be defined', function() {    
        expect(scope).toBeDefined(); // fails
      });

    });
});

I have successfully tested controllers in my main module, however, this particular module is testing my sanity.

Any ideas ?

EDIT:

Karma file:

files: [
      'app/bower_components/angular/angular.js',
      'app/bower_components/angular-resource/angular-resource.js',
      'app/bower_components/angular-route/angular-route.js',
      'app/bower_components/angular-animate/angular-animate.js',
      'app/bower_components/angular-cookies/angular-cookies.js',
      'app/bower_components/angular-mocks/angular-mocks.js',
      'app/app.module.js',
      'app/components/**/controller/*.js',
      'app/components/**/model/*.js',
      'app/components/**/test/unit/*.js'
    ]

The service module is defined in app.module.js and the service is at app/components/services/model/myService.js (The path seems illogical, I tried to abstract my structure to generalize this question as much as possible)

EDIT 2:

Karma also seems to not complain: From the log:

28 08 2015 03:38:47.095:WARN [karma]: No captured browser, open http://localhost:9876/
28 08 2015 03:38:47.107:INFO [karma]: Karma v0.13.9 server started at http://localhost:9876/

Followed by the failing test case:

Answer 1

DARN YOU SAFARI!

Solution: Changed the browser to Chrome in the karma config file and the debug log spat out much more detailed information on what was wrong!

Turned out I did not include needed module dependencies in my karma files.
