    $ git grep -nC1 evpciph_aes_siv -- test
    test/recipes/30-test_evp.t-171-push @defltfiles, qw(evpciph_aes_gcm_siv.txt) unless $no_siv;

    $ git grep -nC3 defltfiles -- test | tail -n7
    test/recipes/30-test_evp.t-189-}
    test/recipes/30-test_evp.t-190-
    test/recipes/30-test_evp.t-191-my $conf = srctop_file("test", $defaultcnf);
    test/recipes/30-test_evp.t:192:foreach my $f ( @defltfiles ) {
    test/recipes/30-test_evp.t-193-    ok(run(test(["evp_test",
    test/recipes/30-test_evp.t-194-                 "-config", $conf,
    test/recipes/30-test_evp.t-195-                 data_file("$f")])),

Therefore, given also:

    test/recipes/30-test_evp.t:39:my $defaultcnf = $no_legacy ? 'default.cnf' : 'default-and-legacy.cnf';

The test is:

    $ ./util/wrap.pl ./test/evp_test -config test/default.cnf \
        test/recipes/30-test_evp_data/evpciph_aes_siv.txt 2>&1 |
        grep -E 'ok |RUNNING' | uniq -c
          6     # RUNNING TEST FOR CIPHER AES-128-SIV
          1     # RUNNING TEST FOR CIPHER AES-192-SIV

        148     # RUNNING TEST FOR CIPHER AES-128-SIV
        147     # RUNNING TEST FOR CIPHER AES-192-SIV
