Running devel::cover recursively on directory with .t files

[david2008]

Hi all,

I have a directory with many subdirectories(more than one level) and want to have one devel::cover run on all these files.
I tried to write the program run_tests.pl

use strict;
use warnings;
use File::Find;
use TAP::Harness;

my ($base_dir) = @ARGV;

my @tests;
 find(\&wanted, $base_dir);
 
 
 my $harness = TAP::Harness->new();
 $harness->runtests(@tests);
 
 sub wanted {
     if($File::Find::name !~ /\.t$/) {
         return;
     }
     push @tests, "$File::Find::name";
 }

but when running
perl -MDevel::Cover run_tests.pl testdir
and afterwards
cover -report
I just get the coverage of the run_tests.pl

---------------------------- ------ ------ ------ ------ ------ ------ ------
File stmt bran cond sub pod time total
---------------------------- ------ ------ ------ ------ ------ ------ ------
t/run_tests.pl 100.0 100.0 n/a 100.0 n/a 100.0 100.0
Total 100.0 100.0 n/a 100.0 n/a 100.0 100.0
---------------------------- ------ ------ ------ ------ ------ ------ ------

What could be the solution for the problem?
Thanks,
David

I guess you'll need to load Devel::Cover for the tests you run and not for the test harness you're using. Test::Harness says that $ENV{HARNESS_PERL_SWITCHES} is the way to go. So either set the $switches variable that Test::Harness alludes to exporting, or set HARNESS_PERL_SWITCHES=-MDevel::Cover before you run the harness.

Hi,

I switched to test:harness and set the environment variable and it worked great.

Thanks, David
