This sounds like a job for ... Test::Trap!

my $result = trap { $obj->method(@args) }; # or my @results, for list
context
# Possibly:
$trap->warn_is_deeply( \@expected_warnings, "Got exactly the expected
warnings?" );
# ... but usually more usefully:
$trap->stderr_like( $pattern, "Trapped stderr matches expectations" );

$trap->return), and whatever else, from the same call.
