Here are some examples on how to test for error messages using CPAN modules.
Check that code does or does not die (with a specific error message):
use Test::Exception;
dies_ok { testsub("die") } "Dies on inappropriate input";
throws_ok { testsub("die screaming") } qr/arrrgh/, "Dies with appropri
+ate error message";
lives_ok { testsub("survive") } "Survives with appropriate input";
Check that a warning is or is not given:
use Test::Warn;
warning_is { testsub("complain") } qr/nag/, "Gives a specific warning"
+;
warning_is { testsub("quiet") undef, "No warnings given";
Check that none of the tests you run emit a warning:
use Test::NoWarnings;
For this last one you'll have to add 1 to the number of tests you run (in your Test::More plan), which will then pass whether any of the tests in this file emitted a warning.
See the perldoc for each of these modules for further examples and documentation.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
