angularjs - How to provide a service returning different mocked response that is called multiple times -

i trying mock service call gets called multiple times in 1 test, importantly returning different results.

heres example of code i'm testing:

 var myarray = [];  angular.foreach(docs, function(doc) {      myservice.execute().then(function(data) {           myarray.push(data);      });  )}; 

and provide unit tests so:

$provide.service('myservice', function() {     return {         execute: jasmine.createspy('myservice.execute')     }; }); 

so idea can provide mock tests so:

it('should something', function () {      myservice.execute.and.callfake(function() {         var deferred = $q.defer();         deferred.resolve(mock1);         return deferred.promise;     });      // expects array have 'mock1' data in  

so works singular, when doing more assumed calling again might work tried doing this:

it('should something', function () {      myservice.execute.and.callfake(function() {         var deferred = $q.defer();         deferred.resolve(mock1);         return deferred.promise;     });      myservice.execute.and.callfake(function() {         var deferred = $q.defer();         deferred.resolve(mock2);         return deferred.promise;     });      // expected array have 'mock1, mock2' data in  

but doesn't work expected returns mock2 twice, can angular.foreach in test it? i've looked around cant seem find on how achieve want.
