22// NOTE: Odds are this file should not be included in your project.  It is
23// only needed for some enhanced unit testing.
24//
25// By adding:
26//    #define _GTMDevLog _GTMUnitTestDevLog
27// to your prefix header (like the GTM Framework does), this function then
28// works to forward logging messages to the GTMUnitTestDevLog class to
29// allow logging validation during unittest, otherwise the messages go to
30// NSLog like normal.
31//
32// See GTMUnitTestDevLog.h for more information on checking logs in unittests.
