=head1 NAME
Test::If - Test only if ...
=head1 VERSION
Version 0.01

our $VERSION = '0.01';
=head1 SYNOPSIS
Generic usage
use Test::More;
use Test::If 'Test::Something', [ tests => N ];
# Is equal to
use Test::More;
eval q{ use Test::Something; 1 } or plan skip_all => 'Module Test::Something required for this test';
plan tests => N;
use Test::More;
use Test::If sub { $ENV{TEST_AUTHOR} }, [ tests => N ];
# Is equal to
use Test::More;
$ENV{TEST_AUTHOR} or plan skip_all => "Test condition not met";
plan tests => N;
You can also combine options and it is allowed to omit plan options, if it is run by loaded module or you want to load it manually
For example common C<pod-coverage.t>:
use Test::More;
use Test::If
sub { $ENV{TEST_AUTHOR} }, # Checked first $ENV{TEST_AUTHOR}, otherwise skip
'Test::Pod::Coverage 1.08', # Use Test::Pod::Coverage of at least version 1.08
'Pod::Coverage 0.18', # And want Pod::Coverage at least of version 0.18
;
all_pod_coverage_ok();
If some of conditions will not be met, test will be skipped.
