Test window creation

[Luis Mochan]

I wonder how do you 'Test' a module that is related to a graphical
interface. I got failure reports from cpan testers with messages like:

# got: 'couldn't connect to display ":0" at \
/home/cpan/pit/thr/conf/perl-5.24.0/.cpanplus/5.24.0/build/Ss0ihFoAc_/Tk-804.033/blib/lib/Tk/MainWindow.pm \
line 53.
# Tk::MainWindow->new() at t/create.t line 45.

I guess that my testing code should have realized that there was no
available display, skipped the test and issued a warning instead of
failing, but I don't know how to do that. Any suggestion?

Best regards,
Luis
