當在茉莉花單元測試中使用嵌套的描述語句時，爲什麼karma或Webstorm崩潰？錯誤：無法讀取未定義的屬性*

我正在使用WebStorm與karma結合運行Jasmine javaScript單元測試。 如果我嵌套describe陳述，然後業力崩潰，或者它可能是WebStorm崩潰，我不知道。當在茉莉花單元測試中使用嵌套的描述語句時，爲什麼karma或Webstorm崩潰？錯誤：無法讀取未定義的屬性*

的因緣錯誤輸出說道：

ERROR [karma]: [TypeError: Cannot read property 'should return a Foo' of undefined]

如果我直接在茉莉花SpecRunner.html運行測試，一切正常，並測試通過。
如果我刪除嵌套describe語句，那麼一切運行良好。

版本：

OS X：10.9（13A603）
WebStorm：7.0.2
因緣：0.10.8
果報茉莉：0.1.4
jasmine.js：jasmine-1.3.1

是什麼導致它崩潰？

代碼和測試：

var Foo = function Foo(name) { 

    this.name = name; 

}; 

Foo.prototype.bar = function bar() { 

    return "Hello " + this.name; 

}; 


describe("Foo", function() { 


    describe("constructor", function() { 


     it("should return a Foo", function() { 

      var act, 
       target; 

      act = function() { 
       target = new Foo("Gary"); 
      }; 

      expect(act).not.toThrow(); 

      expect(target).not.toBeNull(); 


     }); 


    }); 



    describe("bar", function() { 

     it("should return a string like 'Hello' + name", function() { 

      var target, actValue; 

      target = new Foo("Gary"); 

      actValue = target.bar(); 

      expect(actValue).toBe("Hello Gary"); 


     }); 

    }); 


});
