Question

通过伟大的yeoman generator-ember（版本0.7.1）生成一个ember.js项目后，我尝试使用集成的mocha执行测试。

grunt test

或

npm test

标准测试工作正常，但它不参考Ember项目。所以自己的模型测试抛出

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)

这是上面提到的测试......

'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看起来很不受欢迎：

{
  "name": "mediator",
  "version": "0.0.1",
  "dependencies": {  },
  "devDependencies": {
    "grunt": "~0.4.1",
    "grunt-contrib-copy": "~0.4.1",
    "grunt-contrib-concat": "~0.3.0",

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

更新：将require("ember");添加到测试用例文件时，npm test会抱怨

> 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)

而grunt test很高兴忽略测试文件。

我是否必须以某种方式将与Ember的连接放在一起？最好的方法是怎样的？提前谢谢......

Answer 1

命令行使用的Mocha是Node.js应用程序。

通常，在Node.js中，如果你想使用某些东西，你必须先安装它：

npm install ember

这会将Ember安装在本地node_modules目录中。

然后你必须使用require的电话。在使用mocha进行测试的情况下，在解析这些文件之前，mocha本身会将诸如describe和it之类的调用添加到可用于测试文件的符号中。这是一个特例，但其他一切都必须以某种方式提出。

Ember的Node.js doc说：

require("ember");

和Ember将添加到您的全局命名空间。

通过更新yeoman的ember-generator 0.8.0.并重建项目，这个问题就消失了。
