angularjs - Angular Unit Testing Service with multiple service calls using $q.all -

ok here scenario trying unit test jasmine. have service defined similar service below:

(function () {      'use strict';      angular.module('mymodule')            .service('myservice', myservice);      myservice.$inject = ['$q', '$resource', 'progressservice',              'myservice2', 'myservice3', 'ngdialog'];     function myservice($q, $resource, progressservice,              myservice2, myservice3, ngdialog) {          var self = this;         self.datalistsvc2 = [];         self.datalistsvc3 = [];         self.datafromresource = null;         self.myroutine = myroutine;          var myresource = $resource('/someurl/webapi/getdata');          //trying test routine!!!         function myroutine(param1, param2) {              return progressservice.show($q.all([                 myresource.get({ param1: param1 }).$promise.then(function (response) {                     self.datafromresource = response;                 }),                 myroutine2(param2),                 myroutine3(param2)             ]));          }          function myroutine2(param) {              return myservice2.getsomedata(param).then(function (response) {                 var results = [];                 self.datalistsvc2 = [];                  response.foreach(function (item) {                     item.addfield1 = null;                     item.addfield2 = false;                     results.push(item);                 });                  self.datalistsvc2 = results;             });          }          function myroutine3(param) {              return myservice3.getsomemoredata(param, [6])                 .then(function (response) {                     self.datalistsvc3 = response;                 });         }      } })(); 

i trying write unit test myservice.myroutine() , not having luck, suspect due $q.all array of promises. here test settled on not ideal , don't feel it's testing of value. have tried "mocking" 3 requests $httpbackend no luck 3 responses come in array undefined values. searched around , web , finding $q.all([]) unit tests referencing controllers not services. if has input appreciated. here settled time being:

describe('my service: ', function () {         var $httpbackend;          beforeeach(module('mymodule'));          beforeeach(inject(function ($injector) {             // set mock http service responses             $httpbackend = $injector.get('$httpbackend');         }));          it('can call myroutine myservice', inject(function (myservice) {              //arrange             var expectedval1 = 1234;             var expectedval2 = 1234;              spyon(myservice, "myroutine");              //act             myservice.myroutine(expectedval1, expectedval2);              //assert             expect(myservice.myroutine).tohavebeencalled();          })); }); 

use $httpbackend.when('get', '/someurl/webapi/getdata').respond(data); fake http requests. should fake myservice2.getsomedata method , myservice3.getsomemoredata guess methods create http request fake them in same manner.

expect(myservice.myroutine).tohavebeencalled(); 

is irrelevant called manually ;-).

var fixture = {/*some data ... */};    it('can call myroutine myservice', inject(function (myservice) {          $httpbackend.when('get', '/someurl/webapi/getdata').respond(fixture);             //act             myservice.myroutine(expectedval1, expectedval2);             $rootscope.$apply()             //assert             expect(myservice.datafromresource).tobe(fixture);          }));
