#        Regression test for Image Factory #bug740592
#        Created by koca (mkoci@redhat.com)
#        Date: 28/11/2011
#        Issue: aeolus-configure creates a /etc/rhevm.json file which imagefactory uses to push
#               images to rhevm.  The latest version of imagefactory now expects this in
#               /etc/imagefactory directory.
# return values:
# 0 - OK: everything OK
# 1 - Fail: setupTest wasn't OK
# 2 - Fail: bodyTest wasn't OK
# 3 - Fail: cleanTest wasn't OK
# 4 - Fail: any other error (reserved value)
