Renée provided a working solution here: http://www.perl-community.de/bat/poard/thread/18420 (German)
use strict;
use warnings;
use TAP::Harness::Archive;
use TAP::Harness;
use TAP::Formatter::HTML;
my $formatter = TAP::Formatter::HTML->new;
my $harness = TAP::Harness->new({ formatter => $formatter });
$formatter->really_quiet(1);
$formatter->prepare;
my $session;
my $aggregator = TAP::Harness::Archive->aggregator_from_archive({
archive => '/must/be/the/complete/path/to/test.tar.gz',
parser_callbacks => {
ALL => sub {
$session->result( $_[0] );
},
},
made_parser_callback => sub {
$session = $formatter->open_test( $_[1], $_[0] );
}
});
$aggregator->start;
$aggregator->stop;
$formatter->summary($aggregator);
Tanks a lot! I hope this will help some others too. It seems like this knowledge is not very wide spread yet.
I have made a module to pack this solution in a nice interface: https://metacpan.org/module/Convert::TAP::Archive
So from now on you can just type this:
use Convert::TAP::Archive qw(convert_from_taparchive);
my $html = convert_from_taparchive(
'/must/be/the/complete/path/to/test.tar.gz',
'TAP::Formatter::HTML',
);
The problem with the output is mentioned in the docs. Please provide patches or comments if you know how to fix this (minor) issue. E.g. here: https://github.com/borisdaeppen/Convert-TAP-Archive
