The form of your test data depends on the kind of rules you are writing. If you 
are aiming to push down a lot of operations down to a particular engine (e.g. 
Druid can handle everything except Join) then you should run on that engine. If 
you are interested mainly in logical transformation rules then the capabilities 
of the engine are less important and you could run on say the Csv adapter. For 
convenience & familiarity I use JDBC_SCOTT, and if I want a larger data set 
with a rich model I use JDBC_FOODMART.

Lastly, if you are writing unit tests for correctness of the rules, and don’t 
want to execute queries, create a sub-class of RelOptRulesTest.
