未知`服务：在灰烬航线单元测试session`注射器

Question

我在路线简单登入我的灰烬应用程序：

import Ember from 'ember'; 
import UnauthenticatedRouteMixin from 'ember-simple-auth/mixins/unauthenticated-route-mixin'; 

export default Ember.Route.extend(UnauthenticatedRouteMixin, { 
}); 

而对于不是更复杂的单元测试：

import { moduleFor, test } from 'ember-qunit'; 

moduleFor('route:sign-in', 'Unit | Route | sign in', { 
    needs: ['service:session'] 
}); 

test('it exists', function(assert) { 
    let route = this.subject(); 
    assert.ok(route); 
}); 

但运行ember test -f sign当它失败，错误告诉我，它不能注入service:session：

我试图找到解决方案，但是我发现的一切都是关于集成测试，或者告诉我添加needs: ['service:session']，但它已经在那里。

也适用于我。我认为这是因为在您的应用程序中找不到session服务（它在插件中）。尽管如此，请不要听我的话。

无论如何，你可以做的是将会话对象本身存储在路由主题中而不是需要。

例如

test('it exists', function(assert) { 
    let route = this.subject({session: Ember.Object.create()}); 
    assert.ok(route); 
}); 

的问题存在，如果你需要在会​​话像session.get('isAuthenticated')东西，因为你根本存根空session就会失败。所以，你应该存根，而不是像这样：

let route = this.subject({session: Ember.Object.create({isAuthenticated: true}); 

提示：创建一个测试辅助创建会话存根将是有益的。
