karma and requirejs with angular

I having troubles to setting the above working together.

I want to implement karma testing in my project, the problem is that the require modules are not defined in the test.

Here is my karma.config.js:

module.exports = function(config) {
  config.set({

    // base path that will be used to resolve all patterns (eg. files, exclude)
    basePath: '',


    // frameworks to use
    // available frameworks: http://ift.tt/1ft83uu
    frameworks: ['jasmine', "requirejs"],


    // list of files / patterns to load in the browser
    files: [
      {pattern: 'app/scripts/**/*.js', included: false, served: true},
      {pattern: 'test/spec/**/*.js', included: false, served: true},
     "test/main-test.js"
    ],




    // list of files to exclude
    exclude: [
      'app/require-main.js'
    ],


    // preprocess matching files before serving them to the browser
    // available preprocessors: http://ift.tt/1gyw6MG
    preprocessors: {
    },


    // test results reporter to use
    // possible values: 'dots', 'progress'
    // available reporters: http://ift.tt/1ft83KQ
    reporters: ['progress'],


    // web server port
    port: 9876,


    // enable / disable colors in the output (reporters and logs)
    colors: true,


    // level of logging
    // possible values: config.LOG_DISABLE || config.LOG_ERROR || config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG
    logLevel: config.LOG_DEBUG,


    // enable / disable watching file and executing tests whenever any file changes
    autoWatch: false,


    // start these browsers
    // available browser launchers: http://ift.tt/1ft83KU
    browsers: ['PhantomJS'],


    // Continuous Integration mode
    // if true, Karma captures browsers, runs the tests and exits
    singleRun: true

  });
};

Here is my main-test.js:

var tests = [];
for (var file in window.__karma__.files) {
  if (window.__karma__.files.hasOwnProperty(file)) {
    if (/Spec\.js$/.test(file)) {
      tests.push(file);
    }
  }
}
requirejs.config({
  // Karma serves files from '/base'
  baseUrl: '',

  paths: {
    "requireMain": "app/scripts/require-main"
  },

  shim: {
  },

  // ask Require.js to load these files (all our tests)
  deps: tests,

  // start test run, once Require.js is done
  callback: window.__karma__.start
});

Here is my require-main.js (shorten):

require.config({
    paths: {
        //bootstrap
        app: "app",
        ...


        //3rd party
        "angular_route": "../3rd-party/angular-route/angular-route",

        //providers


        //services
        ...
        normalizer: "../ext/conf/normalizer",
        ...


        //directives
        "si-daterangepicker": "ng-directives/si-daterangepicker",
    },
    shim: {
        "angular" : {
            deps: ["jquery"],
            "exports" : "angular"
        }
     .....

});

and I have this normalizerSpec.js test file:

define(['app', 'normalizer'], function(app) {
  console.log("bew");
  describe("service: normalizer", function () {
    var normalizer;

    beforeEach(module("app"));

    beforeEach(inject(function (_normalizer_) {
      normalizer = _normalizer_;
    }));

    var params = {};
    var metadata = {};
    var data = {};

    var response = normalizer.topLanguagesHybrid(metadata, data, params);

    var type = typeof response;
    expect(type).toEqual("object");
  });
});

The error that I am getting is:

Note: My project is working with requirejs, how can I make karma see all its dependencies as they are set in require-main.js?

Thanks!
