Hello, dear esteemed monks!

I have made a test script that makes cover -t include untested modules into the summary, thus lowering the overall coverage level and the developer's exaggerated ego.

Not even sure how I didn't come up with something like that earlier. So... Here it is:

dallaylaen/todo.t

UPDATE The script doesn't spawn more processes now and runs on Windows. No warnings issued.

#!/usr/bin/env perl

# This script tests nothing (except the fact that modules load w/o war
+nings).
# However, it tries to load them all.
# This means that untested modules would also be included into
# code coverage summary, lowering total coverage to its actual value.

# I.e. having a well-covered module and a totally uncovered one will r
+esult
# in 50% coverage which is probably closer to truth.

use strict;
use warnings;
use Test::More;
use FindBin qw($Bin);
use File::Basename qw(dirname);
use File::Find;

# Try to load EVERY module in t/../lib
my $path = dirname($Bin)."/lib";
my @files;

find (sub {
    /\.pm$/ or return;
    -f $File::Find::name or return;

    $File::Find::name =~ s#^\Q$path\E[/\\]##;
    push @files, $File::Find::name;
}, $path);

# Save warnings for later
my @warn;

foreach my $file (@files) {
    # This sub suppresses warnings but saves them for later display
    local $SIG{__WARN__} = sub {
        push @warn, "$file: $_[0]";
    };

    ok ( eval{ require $file }, "$file loaded" )
        or diag "Error in $file: $@";
};

# print report
foreach (@warn) {
    diag "WARN: $_";
};

# If you are concerned about cover -t, then probably warnings during l
+oad
# are not OK with you
is( scalar @warn, 0, "No warnings during load" );
