    Test::FailWarnings - Add test failures if warnings are caught

VERSION
    version 0.002

SYNOPSIS
    Test file:

        use strict;
        use warnings;
        use Test::More;
        use Test::FailWarnings;

        ok( 1, "first test" );
        ok( 1 + "lkadjaks", "add non-numeric" );

        done_testing;

    Output:

        ok 1 - first test
        not ok 2 - Caught warning
        #   Failed test 'Caught warning'
        #   at t/bin/main-warn.pl line 7.
        # Warning was 'Argument "lkadjaks" isn't numeric in addition (+) at t/bin/main-warn.pl line 7.'
        ok 3 - add non-numeric
        1..3
        # Looks like you failed 1 test of 3.

DESCRIPTION
    This module hooks $SIG{__WARN__} and converts warnings to Test::More's
    "fail()" calls. It is designed to be used with "done_testing", when you
    don't need to know the test count in advance.

    Just as with Test::NoWarnings, this does not catch warnings if other
    things localize $SIG{__WARN__}, as this is designed to catch *unhandled*
    warnings.

USAGE
  Overriding $SIG{__WARN__}
    On "import", $SIG{__WARN__} is replaced with
    "Test::FailWarnings::handler".

        use Test::FailWarnings;  # global

    If you don't want global replacement, require the module instead and
    localize in whatever scope you want.

        require Test::FailWarnings;

        {
            local $SIG{__WARN__} = \&amp;Test::FailWarnings::handler;
            # ... warnings will issue fail() here
        }

    When the handler reports on the source of the warning, it will look past
    any calling packages starting with "Carp" or "warnings" to try to detect
    the real origin of the warning.

  Allowing warnings from dependencies
    If you want to ignore failures from outside your own code, you can set
    $Test::FailWarnings::ALLOW_DEPS to a true value. You can do that on the
    "use" line with "-allow_deps".

        use Test::FailWarnings -allow_deps =&gt; 1;

    When true, warnings will only be thrown if they appear to originate from
    a filename matching "qr/^(?:t|xt|lib|blib)/"

  Allowing warnings from specific modules
    If you want to white-list specific modules only, you can add their
    package names to @Test::NoWarnings::ALLOW_FROM. You can do that on the
    "use" line with "-allow_from".

        use Test::FailWarnings -allow_from =&gt; [ qw/Annoying::Module/ ];

SEE ALSO
    *   Test::NoWarnings -- catches warnings and reports in an "END" block.
        Not (yet) friendly with "done_testing".

    *   Test::Warn -- test for warnings without triggering failures from
        this modules
