Yes, thank you!

I'd stumbled across that thread, wasn't sure it would work, but it does (with weird output, though):

Test::Builder->BAILOUT("oh no");
# outputs:
# tests_sante_reporting/02-infocentre-sanity.......NOK 1FAILED--Furthe
+r testing stopped: oh no
# # Looks like you planned 2 tests but only ran 1.

Test::Builder->BAILOUT("oh no\n");
# outputs (yes, like this):
# # tests_sante_reporting/02-infocentre-sanity.......NOK 1# Looks like
+ you planned 2 tests but only ran 1.
# FAILED--Further testing stopped: oh no

Test::Builder->BAILOUT("\noh no\n");
# outputs (yes, also like this):
# tests_sante_reporting/02-infocentre-sanity.......NOK 1# Looks like y
+ou planned 2 tests but only ran 1.
# FAILED--Further testing stopped.

I think I'm going to go with number 1.

I tried it like this, and it works. BAILOUT is doable. I designed it to have failing tests just to see what happens...

#!/usr/bin/perl

use strict;
use warnings;
use Test::Builder;
use Test::More;

BEGIN { 
        use_ok( 'Test::Simple ' ); 
}

my $Exit_Code;
BEGIN {
        *CORE::GLOBAL::exit = sub { $Exit_Code = shift; };
}

my $output;
my $TB = Test::More->builder;
$TB->output(\$output);

my $Test = Test::Builder->create;
$Test->level(0);

$Test->plan(tests => 3);
plan tests => 1;

$Test->is_eq( $output, <<'OUT' );
1..3
Bail out!  Sayonara!
OUT

if ($Test) {
      $Test->is_eq( $Exit_Code, 255 );
      $Test->ok( $Test->can("BAILOUT"), "Backwards compat" );
}
else {
     BAILOUT(print  "Sayonara!\n");
}
