| Subject: | Fails without X display |
The test suite fails if the machine does not have a running X server:
...
PERL_DL_NONLAZY=1 "/opt/perl-5.29.7/bin/perl5.29.7" "-MExtUtils::Command::MM" "-MTest::Harness" "-e" "undef *Test::Harness::Switches; test_harness(0, 'blib/lib', 'blib/arch')" t/Renard/Incunabula/Frontend/Gtk3/*.t
Unable to init server: Could not connect: Connection refused
(Helper.t:24346): Gtk-WARNING **: 07:34:30.223: cannot open display:
t/Renard/Incunabula/Frontend/Gtk3/Helper.t ..
Dubious, test returned 1 (wstat 256, 0x100)
Failed 2/2 subtests
...
Probably it should detect this situation, and skip the test suite.
