Error: [$injector:unpr] Unknown provider: DSCacheFactoryProvider <- DSCacheFactory <- myService

[Guru I]

Implemented angular-cache for certain time consuming http request in my app.  App works great but seems my unit tests are failing with above error...

in karma.conf.js i added this

'app/bower_components/angular-cache/dist/angular-cache.js',

1) I added 'angular-data.DSCacheFactory' as dependency in my app.js

2) Implemented dataServiceCache which uses DSCacheFactory to create, remove cache

3) I have dataService which depends on dataServiceCache now.

Everything works fine except my unit tests for controllers (which depends on dataService - which depends on dataServiceCache) are failing. 

Any ideas what mistake im doing here.

dataServiceCache.js -

angular.module('emcdApp')

.factory('dataServiceCache', function(DSCacheFactory){

var dataServiceCache = {};

///code...

/////....

                return dataServiceCache;

});

I am still having this issue and im clueless 

Im loading angular-cache after angular.js

while i did not understand this statement

Angular-cache is a dependency of angular-data and must be loaded before angular-data if you are using angular-data.

Do i need angular-data to be installed. Without angular-data my application runs fine, although i have dependency in my app.js as angular-data.DSCacheFactory

No, you don't need angular-data.js to use angular-cache. Can I see your karma.conf.js and (if you have one) karma.start.js to help you debug?

What i was able to do is to inject a mock of my dataServiceCache which use DSCacheFactory

// load the controller's module

var dataServiceCacheMock;

beforeEach(function(){

module('myApp', function($provide){

$provide.value('dataServiceCache', dataServiceCacheMock);

});

});

Hi

Sorry for this whole confustion, i managed to get my unit tests working again, apparently i was missing the DI in one of my init.js file which is used when i do beforeEach(module('myApp));

I added the dependency there and now all UT passes without any other code change.
