Pickle tests

First; thank you for correcting the translation of the Pickle extension!

Yes, a good state comes as a result of a successful test run. In this case all assertions passed. A failed state is likewise because some assertion failed.

I'm not sure I have a better description of "pending" right now, it is like a not-finished tests where the real state isn't quite clear. It could be "good" or it could be "fail", but it seems like it goes in some direction.

Thanks!

Please do note that I didn't finish going through the translation; it was pretty long, so I didn't have time to more than start looking at it.
