What is `perl-Test-Warnings`

If you’ve ever tried to use Test generated by your tests, combined with the convenience of done_testing to not have to declare a test count, you’ll have discovered that these two features do not play well together, as the test count will be calculated before the warnings test is run, resulting in a TAP error (see examples/test_nowarnings.pl in this distribution for a demonstration). This module is intended to be used as a drop-in replacement for Test done_testing calculates the test count, rather than after. It does this by hooking into done_testing as well as via an END block. You can declare a plan, or not, and things will still Just Work. It is actually equivalent to use Test as warnings are still printed normally as they occur. You are safe, and enthusiastically encouraged, to perform a global search-replace of the above with use Test
