angularjs - how to test and resolve Controller data (.then function()) promise and get orginal Data in Jasmine2

Question

    I am testing a controller that uses a service that returns a promise. I need to resolve promise. I am using Jasmine 2. 

    Here is Spec code

      beforeEach(inject(function ($controller, $rootScope, _myService_, _$q_, _$rootScope_, _$httpBackend_, $http) {


         scope = $rootScope.$new();
         $q = _$q_;
         $httpBackend = _$httpBackend_;
         $rootScope = _$rootScope_;
         myService = _myService_;
$http = $http;
         ctrl =  $controller('Ctrl', { '$scope': scope, 'myService': myService });
     spyOn(myService, "getDateRangeData").and.callThrough();

      }));


        it('getDateRangeData return Data obj', function() {

    myService.getDateRangeData().then(function(response) {
      console.log('Success', response);
    }); 
        scope.$digest()      

      });

service js
function getDateRangeData(obj) {
  return $http({
    method: 'POST',
    url: 'https:URL',
     headers: {
       'Content-Type': 'application/json',
       'X-Auth-Token': self.token
     },
    data: obj
  })
}

Api data is object. or there is another aprroch to get Ctrl return promise to resolve and getData? added sevice js code where request send.

If you want the spyOn to actually use the correct implementation instead of the mock you can use callThrough() instead of callFake().

Try it like this:

spyOn(myService, "getDateRangeData").and.callThrough();
