I re-read Parallel maintenance on many projects, part II: The Testing and decided to try something similar for some of the modules I've been working with (both CPAN and not). Unlike brian_d_foy, I wanted to use Test::Harness::Straps from the get-go. Just to be different. :-)

Starting with the code Schwern posted (that brian_d_foy links to), I modified it slightly to run through all the tests in a given t/, as so: 

use strict;
use warnings;

use Test::Harness::Straps;

my $tester = Test::Harness::Straps->new;

use lib 'blib';

my @failures;
foreach my $file (<t/*.t>) {
    local *STDERR;
    my %results = $tester->analyze_file( $file );

    push @failures, $file unless $results{passing};
}

if (@failures) {
    print scalar(@failures), " files failed.\n";
    local $"=$/;
    print "@failures\n";
}
else {
    print "All tests succeeded.\n";
}

When all the tests pass, I get a nice "All tests succeeded." message. But, when the tests fail, especially due to a module that doesn't compile, a bunch of messages appear on STDERR and local *STDERR; doesn't fix that. Turns out it's cause the test file is being run in a sub-process.

Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
