## NAME
    [Log::Log4perl::Appender::TestFileCreeper](https://www.chedong.com/phpMan.php/perldoc/Log%3A%3ALog4perl%3A%3AAppender%3A%3ATestFileCreeper/markdown) - Intentionally slow test appender

## SYNOPSIS
        use [Log::Log4perl::Appender::TestFileCreeper](https://www.chedong.com/phpMan.php/perldoc/Log%3A%3ALog4perl%3A%3AAppender%3A%3ATestFileCreeper/markdown);

        my $app = [Log::Log4perl::Appender::TestFileCreeper](https://www.chedong.com/phpMan.php/perldoc/Log%3A%3ALog4perl%3A%3AAppender%3A%3ATestFileCreeper/markdown)->new(
          filename  => 'file.log',

        );

        $file->log(message => "Log me\n");

## DESCRIPTION
    This is a test appender, and it is intentionally slow. It writes out one byte at a time to
    provoke sync errors. Don't use it, unless for testing.
