In Nutch we have numerous testing scenarios which simulate persistence of data to Gora in some form or other. It has worked good as until now.
Now that gora-sql-0.1.1-incubating artifact is non-compatible with gora-core 0.3, there is a requirement to address this situation in order to keep some degree of integrity within the Nutch codebase.
Specifcally a number of tests  all extend a Util testing class which utilizes functionality from the gora-sql artifact.
My initial solution was to switch to using MemStore... which brought me to logging this issue!
I've logged sub issues here to make clear distinction about my observations.
