How to make ti-mocha's error message more detailed?

[shensi...@gmail.com]

hi all,

  I am using TiShadow for running spec tests, but the error message is not detailed enough and very hard to understand where is wrong: 

for example,  one failed message is: 

  1) should open home.xml:  "before each" hook:

     TypeError: undefined is not a function

      at new Controller (eval at custom_require (api/PlatformRequire.js:24:99))

      at Object.createController (eval at custom_require (api/PlatformRequire.js:24:99))

      at Context.<anonymous> (eval at custom_require (api/PlatformRequire.js:24:99))

      at Hook.run (lib/ti-mocha.js:4332:32)

      at next (lib/ti-mocha.js:4609:10)

      at lib/ti-mocha.js:4626:5

      at Titanium.timeslice (lib/ti-mocha.js:5692:27)

There is no information about which line of code in my controller( app/controllers/home.js)  or view( app/views/home.xml) caused this error. 

Is there any suggestion? 

thanks,

Siwei
