Navigating to Jasmine tests?

In our project, I can press Command+Shift+T to flip between a test file and implementation file in Ruby. It's quite handy!

It doesn't seem to work for our Backbone Models and their tests, though. If I'm editing a file called
app/assets/javascripts/backbone/models/case.js and press Command+Shift+T, nothing happens. (The pulldown menu doesn't work either.)

I would expect Navigate To Test to open the appropriate spec file called
spec/javascripts/backbone/models/case_spec.js

Am I missing something in my configuration, or is this a missing feature/bug?

We're using latest RubyMine EAP, build 132.666 on MacOS 10.8.5.

Thanks!


PS: Navigate To Related Option+Command+Home doesn't work either.
