#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
#Furthermore, we need additional tests for:
#Z3950SearchAuth, BreedingSearch, ImportBreedingAuth

#Group 1: testing _build_query and _translate_query (part of Z3950Search)
subtest '_build_query' => sub {

#Group 2: testing _create_connection (part of Z3950Search)
subtest '_create_connection' => sub {
    plan tests => 5;
    test_create_connection();
};
#Group 3: testing _do_xslt_proc (part of Z3950Search)
subtest '_do_xslt_proc' => sub {
    plan tests => 6;
    test_do_xslt();
};
