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.
NOTE: Backported from v0.9-dev.
This cannot be implemented for previous versions of PHP because we
need socket_import_stream() to extract the underlying socket resource
from the stream in order to be able to set the TCP_NODELAY flag.
This class works just like Predis\Connection\PhpiredisConnection but
it does not require the socket extensions since it relies on PHP's
native streams thus allowing the use of persistent connections.
