[rules-users] Guvnor test scenarios for rules that use globals

[lhorton]

The project I'm on needs to be stable by the end of this month for rules.  We
started evaluating Guvnor in April (5.1 release).  We ran into several
problems.  For example:

enums didn't work in guided rules
loading some rule spreadsheets failed
we have domain classes with private no-arg constructors and Guvnor didn't
handle these by reflection
above classes also couldn't be used in guided tests
inability to test rules that used globals

I know some of these have been fixed (you fixed the spreadsheet problem that
I had, I think) but our evaluation was that we could not wait to see if
things got fixed in time, and my management had resistance to changing our
domain model to conform to Guvnor requirements.  We had a vision that Guvnor
would allow non-technical business people write rules, but we ended up
having to write technical rules due to the various problems.

We also found that writing DRL and using spreadsheets outside guvnor for our
rules was working ok, and it was much easier to maintain everything under
our own IDE (e.g. keeping domain model in synch with rules; archiving;
deploying).

Guvnor looks like it is improving with every release.  I will keep
re-evaluating it when new releases come out.
