As best as I can tell, this package represents a testing framework and parser tester that has long since been antiquated by JUnit integration into our build. Moveover, this package represents much of the tight coupling that blocks / makes very difficult any progress on GEODE-5803.

I was actually thinking of moving these to geode-junit. This is the framework used for testing geode examples. It's currently only used for the old examples. The new examples lack tests.

I always forget to check the examples!

Well, this might be the fastest I've ever opened, gotten feedback, and closed a ticket.

My main concern is that having one module's test source set depend on other module's active test source set is a serious anti-pattern in gradle. Moving this to geode-junit:main would be the other solution.
