how to share scope in angular-ecmascript6 controller while unit-testing in SinonJS

How can I share scope in SinonJs.

Here is my snippet for your reference:

// set up the mock
  beforeEach(() => {

    MockHomeApiService = function () {
      return {
        requestForEarlyAccess: ()=>{
          console.log("homeApiService.requestForEarlyAccess");
        } 
      }
    };

    MockTranslate = function () {
      return sinon.stub().resolves("true");
    };

  });


  // set up the angular mocks
  beforeEach(() => {
      // provide the 
      module(($provide) => {
        $provide.service('homeApiService', MockHomeApiService);
        $provide.service('$translate', MockTranslate);
      });

      // you can surround any injected dependencies with _ _ and    // the injector will throw them away, it's just to        // differentiate between variables that you might want to     // use for tests.
      inject((_$q_, _$timeout_, _homeApiService_, _$translate_) => {

          $q = _$q_
          // having $timeout is often useful for testing that
          // promises have been fulfilled
          $timeout = _$timeout_;

          // set up sinon-as-promised, otherwise it won't work!
          sinonAsPromised($q);


          homeApiService = _homeApiService_;
          $translate = _$translate_

      });
  });


// set up your controller using mocked dependencies
  beforeEach(() => {
    controller = new ApplyController(homeApiService,  userAlertsService, $log, $translate);
  });
