Maybe a quick comparison with mocha (used by firefox os) would be worth it,
since karma can run mocha tests too. I wouldnt spend too much time on it
though.

Yes!

Yeah, we can use the check command and run karma for the js modules.

Which should just work if we use the check command.

Something else I would like to provide is a way to take screen snapshots.
The tests could request the webview to generate a snapshot with a certain
id (we could use an alert with a well known text, in lack of a better
communication mecanism, could be done more cleanly with a plugin but
probably not worth it for tests). At the end of test run, the runner would
compare the snapshots with those in test/snapshot and complain about
differences. It's trivial to implement and should be pretty useful for
testing visual stuff.
