-----------------------------------------
[~asherman] the patch has a simple sample testcase; but for a real life
example; I'm using it in my wip branch
[here|https://github.com/kgyrtkirk/hive/blob/79acdc7a65c3e01547178e38ee3fbad503477048/ql/src/test/org/apache/hadoop/hive/ql/plan/mapping/TestCounterMapping.java#L138].
> JUnit rule to enable Driver level testing

> I've tried to write a case for a sophisticated check...it worked so well that
> I've started using it and eventually created a junit rule to make it easier
> to reuse
> Currently it takes ~15-25sec to run a test case with this framework (from
> which most of the time is the launch time of all kind of stuff which are
> needed to run a driver command).
> * enable to write JUnit tests which has access to the {{IDriver}} level
> * leave out the cli-driver; it sometimes causes problems
> * write tests at the {{ql}} module
> * it should also work from the IDE without changing anything
> Note: JUnit 5 would be great for this task; but unfortunately junit5 needs
> maven-surefire 2.19.1 ; which causes all kinds of problems for hive devs
> using idea...so that's not an option.
