Re: More extensive unit testing and code coverage report?

Looks fine, I already committed it into the trunk.

I took this opportunity to update junit for whole project (to 4.8.2) but
now I'm facing some issues with that.. anyway, not your problem. I
should have this solved by end of today.

So, I'll close that issue and mark it as fixed. You don't need to create
new one for new tests, just add another attachment to this one and
reopen/comment.

Thanks,
Pavel
