On a headless linux system:
...
PERL_DL_NONLAZY=1 "/opt/perl-5.28.0/bin/perl" "-MExtUtils::Command::MM" "-MTest::Harness" "-e" "undef *Test::Harness::Switches; test_harness(0, 'inc', 'blib/lib', 'blib/arch')" t/Gtk3-Ex-PdfViewer.t
Unable to init server: Could not connect: Connection refused
(Gtk3-Ex-PdfViewer.t:24911): Gtk-WARNING **: 14:14:33.101: cannot open display:
t/Gtk3-Ex-PdfViewer.t ..
Dubious, test returned 1 (wstat 256, 0x100)
No subtests run
...
Probably the test file should first check if the display can be opened at all --- not sure how to do this with Gtk. With Tk I would do something like:
my $mw = eval { tkinit };
plan skip_all => "Cannot create MainWindow: $@" if !$mw;
