angularjs - Mocking collaborators in Angular controller and service Jasmine tests -

i have been writing jasmine unit tests in angular. in first example i'm testing controller.

myapp.controller('myctrl', function($scope, config){     ... }); 

i have configuration service (config) keeps configuration database , injected controller. unit test, want mock out configuration service altogether, rather allowing execution pass through , using $httpbackend. examples found taught me $controller function can use this, in order instance of controller mocks injected in place of usual collaborator:

beforeeach(inject(function($controller, $rootscope){   var scope = $rootscope.$new();   var configmock = {      theonlypropertymycontrollerneeds: 'value'   };   ctrl = $controller('myctrl', {             $scope:scope,              config: configmock         }); })); 

but have other services use config service. unit test them, assumed there similar $service function use instantiate service whatever mocks want provide. there isn't. tried $injector.get, doesn't seem let me pass in mocks. after searching while, best come in order instantiate service in isolation (avoid instantiating collaborators) this:

beforeeach(function() {   mockconfig = {      thepropertymyserviceuses: 'value'   };    module(function($provide) {     $provide.value('config', mockconfig);   });    inject(function($injector) {     myservice = $injector.get('myservice');   }); }); 

is right way? seems overriding entire application's definition of config service, seems maybe overkill.

is way? why there no $service helper method?

for unit testing, common override service sake of testing. however, can use $provide override existing service instead of using inject, long load application before hand.

assuming created config using like:

angular.moduel('...', [...]).factory('config', function (...) {...}); 

if so, try this:

... beforeeach(module("<name of app>"));  beforeeach(     module(function ($provide) {         $provide.factory('config', function (...) {...});     }); ); ... 

after that, when initialise controller, mocked config.
