They are broken, because Joseph ripped out the gruntfile without taking a look what it was doing.
You can take a look at what is missing here [1].
Intermediate solution
$ npm install -g mocha karma coffee-script
$ mocha --compilers coffee:coffee-script # Unit server tests
$ karma start --single-run # Unit browser tests
For more info on karma see here [2], but the second command won't execute as you need
to run a test server in test/helpers/server.coffee as you can see in the grunt file that was removed.
So no need to feel dumb, it's just broken.
Cheers
