package Installcheck::Changer;
=head1 NAME
Installcheck::Changer - utilities for testing changers
=head1 SYNOPSIS
use Installcheck::Changer;
my $res_cb = sub {
my ($err, $res) = @_;
chg_err_like($err,
{ message => "expected msg", type => 'failure' },
"operation produces the expected error");
# or, just looking at the message
chg_err_like($err,
qr/expected .*/,
"operation produces the expected error");
};
=head1 USAGE
The function C<chg_err_like> takes an C<Amanda::Changer::Error> object and a
hashref of expected values for that error object, and compares the two. The
values of this hashref can be regular expressions or strings. Alternately, the
function can take a regexp which is compared to the error's message. This
function is exported by default.
