用于单元测试的EmberJS服务注入（Ember QUnit） [英] EmberJS Service Injection for Unit Tests (Ember QUnit)

问题描述

规格：

• Ember版本：1.13.8


• 节点：0.10.33


• npm：2.13.4

我有

使用别名作为示例，因为我不允许显示实际的代码）

我已经尝试初始化服务，但在Ember Qunit测试，控制器没有注入到他们的服务。

我已经尝试将注入：init（）而不是beforeEach，不工作...

在单元测试中如何注入？

我将调试器中的断点看看我的控制器是否有服务，它不会在测试期间。但是，在正常的Ember服务器上可以正常使用。

解决方案

您不必输入服务。您必须在下面的需求中包含服务。

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

例如：

服务/别名.js

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

controllers / test.js

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

tests / unit / controllers / test-test.js

  moduleFor（'controller：test'，{
 needs ：['service：store'] 
}）; 
 
 test（'别名别名别名'，函数（assert）{
 
 var controller = this.subject （）; 
 assert.equal（controller.get（'store.name'），'john）; 
 
}）; 
  pre> 
 
 
为了运行此测试，Ember将生成一个容器，其中包含控制器测试和服务别名，所以您可以访问名称为前缀的服务属性。
 
Specs:


Ember 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 'alias' as example because I'm not allow to show actual code)

I've tried to initialize the service but during Ember Qunit tests, controllers do not have the services injected to them.

I've tried putting the injection in: init() instead of beforeEach, doesn't work either...

How do I inject it during unit tests?

I put break points in the debugger to see if my controllers have the service, it doesn't during tests. It's fine on normal ember serve, however.
解决方案
You don't have to import service. You have to include service in needs like below.
moduleFor("controller:test", {
   needs: ['service:alias']
});
For eg:

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/unit/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 to run, Ember will generate a container with the controller test and service alias. So you can access the service properties with its name prefixed.
