# Main object of this unit test is the Breeding module and its subroutines
# A start has been made to define tests for subroutines of Z3950Search.
# These subroutines are actually internal, but these tests may pave the way for
# a more comprehensive test of Z3950Search itself.
#
# TODO We need additional tests for Z3950SearchAuth
