Yes I agree, I will give a look to Mocha.  Maybe QUnit too.

The thing is, in the Karma server you don't see you web application, but this:

http://dev.laptop.org/~manuq/karma.png

The real information appears in the command line:

[sugar-build sugar-html-graphics-manuq]$ karma start
INFO [karma]: Karma server started at http://localhost:9876/
INFO [Chrome 26.0 (Linux)]: Connected on socket id VrmGeTEdSMYWd82R6Emw
Chrome 26.0 (Linux): Executed 2 of 2 SUCCESS (0.517 secs / 0.021 secs)

and the good thing is that by default it will watch your JS files for
changes and run the tests again.  That's why I was thinking in a new
sugar-build command.  Of course the auto-run can be switched off and
then the check can be added to make check, I'm +1 to that.
