Test Summary Report
-------------------
t/callback.t   (Wstat: 2816 Tests: 5 Failed: 1)
  Failed test:  5
  Non-zero exit status: 11
  Parse errors: Bad plan.  You planned 8 tests but ran 5.
Files=8, Tests=275,  2 wallclock secs ( 0.14 usr  0.06 sys +  1.64 cusr  0.63 csys =  2.47 CPU)
Result: FAIL

Please ignore the execution hint, that's an interactive test and doesn't help the problem with callback.t :)

Also, the test does work just fine, and this doesn't appear to be related to the other T-RL-Gnu bug #690274 or bug #595346
Comment 2 Kent Fredric (IRC: kent\n) (RETIRED) gentoo-dev 2020-04-26 17:26:22 UTC
Ooh, I remember where I saw this last. Maybe Tk is trying to load ... and if it is, then this test requires X11. Yay.

grep  -E "(use|require)\s*Tk" -nr .
./t/callback.t:47:    if (eval "use Tk; 1" && $ENV{DISPLAY} && $ENV{DISPLAY} ne '') {
./t/callback.t:48:	ok(1, 'use Tk');
./eg/perlsh:454:	    use Tk;
./eg/ptksh+:12:#	use Tk;
./eg/ptksh+:19:use Tk;
./eg/ptksh+:29:use Tk;
./blib/man1/perlsh.1:156:\&            use Tk;
./blib/script/perlsh:454:	    use Tk;


Uhuh. Yep. Omg.

Reproducing a similar failure:

env DISPLAY="doesntexist" perl -Mblib t/callback.t 
1..8
ok 1 - load done
ok 2 - An object of class 'Term::ReadLine' isa 'Term::ReadLine'
ok 3 - 'Attribs' isa 'Term::ReadLine'
ok 4 - use Tk
not ok 5 - undef isa 'MainWindow'
#   Failed test 'undef isa 'MainWindow''
#   at t/callback.t line 76.
#     undef isn't defined
Cannot continue...
# Looks like your test exited with 25 just after 5.
