The command returns the response as is, but it would probably be not a
bad idea to parse it to restructure returned info using named arrays,
making it easier to access single commands and their info.
We will keep it as is for now, and investigate this change later.
We now have a base test case class for Predis (namely PredisTestCase)
grouping various commonly used utility methods shared by all of the
tests in the suite, greatly improving reusability.
