how can I unit test Service2 which depends on Service1? I keep getting a Service1Provider not found error.

app.js

!function(ng){
  'use strict';
 
  var module = ng.module('foo.services', []);
  
  (function($ng, $module) {
    function Service($q) {
       
        return {
            bar: function(a,b,c){
                
                var baz = a+b+c;
                return function(d,e,f){
                    
                    var deferred = $q.defer();
                    if(baz > 0){
                      deferred.resolve({result: baz + d + e + f });
                    } else {
                      deferred.reject({ err: 'baz was <= 0'})
                    }
                    return deferred.promise;
                    
                }
            }
        };
    }
 
    $module.factory("Service1", ['$q', Service]);
 
  })(ng, module);
 
   (function($ng, $module) {
    function Service(Service1) {
      
        function doSomething(){
            
            var result;
            var whatever = Service1.bar(5,6,7);
           
             var promise = whatever(8,9,10);
            promise.then(function(data){
                
                result = data.result;
                //data.result should be 45 here
            }, function(err){
                
            });
            
            return result;
        }
        
        return {
            bam:doSomething
        };
    }
 
    $module.factory("Service2", ["Service1", Service]);
 
  })(ng, module);
}(angular);


var myApp = angular.module('myApp',['foo.services']);

service_tests.js

describe('foo service tests', function () {

   beforeEach(function () {
        module('foo.services');
    });
    
    //http://jsfiddle.net/hcabnettek/JJ9Rk/
    it('bam should return 45', inject(function (Service2) {
      
       var expectation = Service1.bam();
       expect(expectation).toBe(45);
    }));
