angularjs - Angular 2 testing with Router - Cannot resolve all parameters for 'Router' -


i'm trying test component injects router in constructor (typescript):

constructor(     private _router: router,     private dispatcher: observer<action>,     fb: formbuilder ) { ... }

and have following test(s):

import { it, inject, injectasync, beforeeachproviders, testcomponentbuilder } "angular2/testing";  import {provide} "angular2/core"; import {formbuilder} 'angular2/common'; import {subject} 'rxjs/subject'; import {router, routeparams} 'angular2/router'; // other imports ...  describe("someinfoedit form", () => {      const actions = new subject<action>(null);      // provide our implementations or mocks dependency injector     beforeeachproviders(() => {          return [             router,             formbuilder,             provide(dispatcher, { usevalue: actions }),             someinfoedit         ];     });      it('should have default data', inject([someinfoedit], (component) => {         expect(component.galtitle.value).toequal("");         expect(component.friendlyurl.value).toequal("");         expect(component.isvisible.value).tobe(false);     })); ...

when test runs error:

cannot resolve parameters 'router'(?, ?, ?). make sure parameters decorated inject or have valid type annotations , 'router' decorated injectable.

please that. love read explanation of what's going on (i read articles on di, so).

i should add code works, no problems. test doesn't.

ok, angular team got working:

import { spylocation } 'angular2/src/mock/location_mock'; import {rootrouter} 'angular2/src/router/router'; import {router, routeroutlet, routerlink, routeparams, routedata, location, router_primary_component} 'angular2/router'; import {   routeconfig,   route,   auxroute,   asyncroute,   redirect } 'angular2/src/router/route_config_decorator'; import {routeregistry} 'angular2/src/router/route_registry'; import {directiveresolver} 'angular2/src/core/linker/directive_resolver';  beforeeachproviders(() => {         return [             routeregistry,             provide(location, { useclass: spylocation }),             provide(router_primary_component, { usevalue: yourcomponentwithrouteconfig }),             provide(router, {useclass: rootrouter}),             formbuilder,             someinfoedit         ];     });

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
