[rules-users] When - Then In DSL Rule

[Stephen Masters]

A simple tip when creating DSLs:

	Write an example rule as DRL first!

:)

Then, if it's working DRL code (get familiar with unit testing rules) use DSL to map 'plain English' phrases to the DRL code you just wrote.

It's then also worth writing a simple unit test around a hand-cranked DSRL rule which uses your DSL, before sticking it in Guvnor.
