I looked the unit tests. I'm looking for something different
I would have different rules that compares varying fields(rather fixed set
of fields) and those are all defined in the database.
1.Rule1 conditions are f1='a' & f2='b' in db
2. Rule2 conditions are f3='c' or f4='d' in db.
how can I create rules programmatically and feed into rule engine?
Please provide some guidance with examples?
