A Perl test file written with Test::More is just a Perl program. @ARGV works there like it does in any Perl program (I know, I use @ARGV in some of my test files.)

Can you post some example code that does not behave as you expect?

Here's a simple script run with Perl 5.8.8:

#!/bin/env perl

use strict;
use warnings;

use Test::More tests => 1;
use Data::Dumper;

print Data::Dumper->Dump([\@ARGV], [qw/ARGV/]);
pass('placeholder');

Upon execution, I'm getting the following:

$ prove -v t.t one two three
t.t ....
1..1
$ARGV = [];
ok 1 - placeholder
ok
Cannot determine source for one at /tools/oss/packages/x86_64-rhel5/pe
+rl/5.8.8-64/lib/5.8.8/App/Prove.pm line 496
$

Okay, I see part of my error. If I run the script directly through the interpreter, I get results:

$ perl t.t one two three
1..1
$ARGV = [
          'one',
          'two',
          'three'
        ];
ok 1 - placeholder
$
[download]

...but is there a way I can pass command-line arguments if I use prove instead? I would like to have the statistics prove provides if possible.

prove does not pass on arguments to the test files. prove assumes that you're trying to run test cases called "one", "two" and "three".

If you need to provide arguments to a test file, you need to run it with perl, not prove:

$ perl t.t one two three

If you really want to use prove then perhaps modify your test file to read its options from environment variables instead.

perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'
