[英]Testing Ember.JS Application fails with ReferenceError: Ember is not defined
通過巨大的yeoman generator-ember
-ember(版本0.7.1)生成ember.js項目之后,我嘗試使用集成的mocha
執行測試。
grunt test
要么
npm test
標准測試可以正常運行,但是它沒有引用Ember項目。 所以自己的模型測試拋出
ReferenceError: Ember is not defined
at Context.<anonymous> (/home/lray/workspace/js/mediator/test/spec/source_model_test.js:9:9)

at Object._onImmediate (/home/lray/workspace/js/mediator/node_modules/mocha/lib/runner.js:254:5)
at processImmediate [as _immediateCallback] (timers.js:330:15)
這是提到的測試...
'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();
})
})
});
})();
我的package.json
看起來很沒動:
{

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

},
"scripts": {
"test": "mocha --recursive test/spec/*.js"
},
"engines": {

}
}
更新: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;
^

而grunt test
愉快只是忽略了測試文件。
我是否必須以某種方式將與Ember的連接組合在一起? 最好的方法是怎么做? 提前致謝...
從命令行使用的Mocha是Node.js應用程序。
通常,在Node.js中,如果要使用某些組件,則必須先安裝它:
npm install ember
這會將Ember安裝在本地的node_modules
目錄中。
然后,您必須使用呼叫來require
。 在使用Mocha進行測試的情況下,在解析這些文件之前,mocha本身it
諸如describe
和it
類的調用添加到可用於測試文件的符號中。 這是一個特例,但其他所有內容都必須以某種方式進行要求。
Ember的Node.js 文檔說:
require("ember");
和Ember
將被添加到您的全局名稱空間。
通過更新yeoman的ember-generator 0.8.0。 然后重建項目,這個問題就解決了。
