perl-Test-Warnings - Test for warnings and the lack of them
- Description:
If you've ever tried to use Test::NoWarnings to confirm there are no warnings
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::NoWarnings: it also adds an extra test, but runs this test before
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::NoWarnings 1.04 ':early';
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::Warnings; whether or not your tests have a plan.
