NAME

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

VERSION

    version 0.008

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 - Test::FailWarnings should catch no warnings

        #   Failed test 'Test::FailWarnings should catch no warnings'

        #   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

    "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__} = \&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 => 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 => [ qw/Annoying::Module/ ];

SEE ALSO

    *   Test::NoWarnings -- catches warnings and reports in an "END" block.

        Not (yet) friendly with "done_testing".

    *   Test::Warnings -- a replacement for Test::NoWarnings that works with

        done_testing

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

        this modules
