=head2 Expensive test method attribute

If a test method is decorated with an Expensive
attribute, it is skipped unless the RUN_EXPENSIVE_TESTS
environment variable is defined.

To declare an entire test class and its subclasses expensive,
define a SKIP_CLASS with the Expensive attribute:

    sub SKIP_CLASS : Expensive { }

=cut

sub Expensive : ATTR(CODE) {
    my ($package, $symbol, $sub, $attr, $data, $phase) = @_;
    my $name = *{$symbol}{NAME};
    if ($name eq 'SKIP_CLASS') {
        if ($ENV{'RUN_EXPENSIVE_TESTS'}) {
            *{$symbol} = sub { 0; }
        } else {
            *{$symbol} = sub { "Skipping expensive test classes $package (and subclasses)"; }
        }
    } else {
        unless ($ENV{'RUN_EXPENSIVE_TESTS'}) {
            # a test method that runs no tests and just returns a scalar is viewed by Test::Class as a skip
            *{$symbol} = sub { "Skipping expensive test $package\:\:$name"; }
        }
    }
}

  returns:
