From 2ef1c56436d25e8a710a8679c59400c0e4009cd6 Mon Sep 17 00:00:00 2001
From: Mike Bayer <mike_mp@zzzcomputing.com>
Date: Fri, 1 May 2015 13:15:51 -0400
Subject: - move away from explicit raises of SkipTest, instead call a function
 patched onto config.  nose/pytest backends now fill in their exception class
 here only when loaded - use more public seeming api to get at py.test Skipped
 exception
