=head1 NAME

Test2::Plugin::NoWarnings - Fail if tests warn

=head1 VERSION

version 0.09

=head1 SYNOPSIS

use Test2::V0;
    use Test2::Plugin::NoWarnings;

...;

=head1 DESCRIPTION

Loading this plugin causes your tests to fail if there any warnings while they
run. Each warning generates a new failing test and the warning content is
outputted via C<diag>.

This module uses C<$SIG{__WARN__}>, so if the code you're testing sets this,
then this module will stop working.

=head1 ECHOING WARNINGS

By default, this module suppresses the warning itself so it does not go to
C<STDERR>. If you'd like to also have the warning go to C<STDERR> untouched,
you can ask for this with the C<echo> import argument:

use Test2::Plugin::NoWarnings echo => 1;

=head1 SUPPORT

Bugs may be submitted at L<https://github.com/houseabsolute/Test2-Plugin-NoWarnings/issues>.

I am also usually active on IRC as 'autarch' on C<irc://irc.perl.org>.

=head1 SOURCE

The source code repository for Test2-Plugin-NoWarnings can be found at L<https://github.com/houseabsolute/Test2-Plugin-NoWarnings>.

=head1 DONATIONS

If you'd like to thank me for the work I've done on this module, please
consider making a "donation" to me via PayPal. I spend a lot of free time
creating free software, and would appreciate any support you'd care to offer.

Please note that B<I am not suggesting that you must do this> in order for me
to continue working on this particular software. I will continue to do so,
inasmuch as I have in the past, for as long as it interests me.

Similarly, a donation made in this way will probably not make me work on this
software much more, unless I get so many donations that I can consider working
on free software full time (let's all have a chuckle at that together).

To donate, log into PayPal and send money to autarch@urth.org, or use the
button at L<https://www.urth.org/fs-donation.html>.
