Debugging mocha chai unit tests in IDEA 12.1.4

Hi

How do I debug a mocha / chai unit test. I want to set breakpoints and step into the code.

currently I saw that there are workarounds that have been written ,  for example runing a testerjs file that runs  the actual mocha tests.

Isnt there a built in way in the intellij IDEA 12.1,4 environment to debug mocha ?

Is there a way in  IDEA 13 ?

Thanks.
