Hi,

from a user's point of view, who has been using Drools Expert in
production for years now, I'm wondering why there aren't *unit tests*
which are capable of answering this basic question in no time?

If test coverage is as low as it seems, can you recommend using Drools
Expert in production with a clear conscience?

Best regards

Ansgar
