EmberJS Service Injection for Unit Tests (Ember QUnit)

Question

Specifications:

• Amber Version: 1.13.8
• node: 0.10.33
• npm: 2.13.4

I have

import Alias from "../../../services/alias"; .... moduleFor("controller:test", "Controller: test", { integration: true, beforeEach: function() { this.register('service:alias', Alias, {singleton: true}); this.inject.service('alias', { as: 'alias' }); this.advanceReadiness(); }, }); ... test('Alias Alias Alias ', function(assert) { var controller = this.subject(); //sample function controller.send("test"); assert.equal(true, controller.alias.get("alias"), "alias should be true"); }); 

(Using an "alias" as an example, because I cannot show the actual code)

I tried to initialize the service, but during the Ember Qunit tests, the controllers do not have the services that were added to them.

I tried to insert an injection in: init () instead of beforeEach, it doesn't work and ...

How do I embed it during unit tests?

I set breakpoints in the debugger to see if my controllers have this service, but not during the tests. However, this is normal on an ordinary ember.

You do not need to import the service. You must enable the service in need, as shown below.

 moduleFor("controller:test", { needs: ['service:alias'] }); 

For example,

service / alias.js

 Em.service.extend({ name: 'john' }); 

controllers / test.js

 Em.Controller.extend({ alias: Em.service.inject(), test: function() { alert(this.get('alias.name'); } }); 

Tests / block / controllers / test-test.js

 moduleFor('controller:test', { needs: ['service:store'] }); test('Alias Alias Alias', function(assert) { var controller = this.subject(); assert.equal(controller.get('store.name'), 'john); }); 

For this test, Ember will create a container with a controller test and service alias . This way, you can access the properties of the service with a name prefix.
