Of course we have a testing suite, but unfortunately we haven't made it public yet. Its form needs a lot of polishing and we haven't got time recently to do that. Also, these articles on wiki are outdated. A lot has changed in CKE4 and we still haven't updated these things.

I think that after 4.2 we will stop coding for a while and move our focus to the tests runner, wiki articles and other resources, because we were coding constantly for like... 2 years. It's a little bit too long now :).

Anyway, I can't give you an access to our tests repo, but I can give you some details if that would be enough to fulfill that requirement :)

E.g. here's a cloc​ result:
