I'm aware that our naming conventions are not the canonical ones, yet remember that the "pure" unit tests will execute very quickly, so we're not really wasting much execution time.

We can talk about moving them, but if we get into that let's remember which integration combinations we want to support. We have both a front-end API axis ORM|Infinispan|Other? and a backend integration axis Lucene|ES|Other(serialization?), and that's on top of the additional axis: for each ORM test we have several databases, and for all of these we have a set of JVM versions, a set of JVM vendors and a set of supported OS es.

+1 to make a rationale plan, but let's not start moving stuff around without a good plan.
