通過ReferenceError測試Ember.JS應用程序失敗：未定義Ember

Question

通過偉大的yeoman generator-ember（版本0.7.1）生成ember.js項目後，我嘗試使用集成的mocha執行測試。

grunt test 

或

npm test 

標準的測試工作正常，但美國能源部不能引用灰燼項目。所以自己的模型試驗拋出

ReferenceError: Ember is not defined 
    at Context.<anonymous> (/home/lray/workspace/js/mediator/test/spec/source_model_test.js:9:9) 
    at Hook.Runnable.run (/home/lray/workspace/js/mediator/node_modules/mocha/lib/runnable.js:213:32) 
    at next (/home/lray/workspace/js/mediator/node_modules/mocha/lib/runner.js:243:10) 
    at Object._onImmediate (/home/lray/workspace/js/mediator/node_modules/mocha/lib/runner.js:254:5) 
    at processImmediate [as _immediateCallback] (timers.js:330:15) 

這是上述試驗...

'use strict'; 

(function() { 

describe('Mediator.Source (Model)', function() { 
    beforeEach(function() { 
    Ember.run(function() { Mediator.reset(); }); 
    Ember.testing = true; 
    }); 
    afterEach(function() { 
     Ember.testing = false; 
    }); 

    describe('initialize like expected', function() { 
     it('should return the given parameters correctly', function(){ 
     var oItem; 
     Ember.run(function() { 
      // Won't actually load until the end of the run-block. 
      oItem = Mediator.Source.find(1); 
     }); 
     expect(oItem.get("id")).to.be.equal("myId"); 
     expect(oItem.get("name")).to.be.equal("myName"); 
     expect(oItem.additional).to.be.false(); 
     }) 
    }) 
}); 
})(); 

我package.json小艾不變：

{ 
    "name": "mediator", 
    "version": "0.0.1", 
    "dependencies": { }, 
    "devDependencies": { 
    "grunt": "~0.4.1",

    "expect.js": "~0.2.0" 
}, 
"scripts": { 
    "test": "mocha --recursive test/spec/*.js" 
}, 
    "engines": { 
    "node": ">=0.8.0" 
    } 
} 

更新：當添加require("ember");到測試用例文件，npm test抱怨

> mediator@0.0.1 test /home/lray/workspace/js/mediator 
> mocha --recursive test/spec/*.js 

module.js:340 
    throw err; 
    ^
Error: Cannot find module 'ember' 
    at Function.Module._resolveFilename (module.js:338:15) 
    at Function.Module._load (module.js:280:25) 
    at Module.require (module.js:364:17) 
    at require (module.js:380:17) 
    at Object.<anonymous> (/home/lray/workspace/js/mediator/test/spec/source_model_test.js:4:1) 

while grunt test幸福地忽略了測試文件。

我是否必須以某種方式將連接安裝到Ember上的方式不同？如何做到這一點最好的方式？在此先感謝...

Answer 1

通過更新yeoman的ember-generator 0.8.0.並重建項目，此問題已消失。

Answer 2

從命令行使用的摩卡是一個Node.js應用程序。

一般來說，Node.js的，如果你想使用你有什麼事情先安裝它：

npm install ember 

這將在本地node_modules目錄中安裝灰燼。

然後，您必須使用致電require。在使用摩卡進行測試的情況下，在分析這些文件之前，通過mocha自己將諸如describe和it的調用添加到可用於測試文件的符號。這是一個特殊情況，但是其他一切都需要以某種方式進行。

爲灰燼Node.js的doc說做：

require("ember"); 

和Ember將被添加到您的全局命名空間。
