Libwhisker is a Perl module geared specifically for HTTP testing.
Libwhisker has a few design principles:

- Portable: runs with 0 changes on Unix, Windows, etc. (100% Perl)
- Flexible: designed with a 'no rules' approach
- Contained: designed to not require external modules when possible
- Localized: does not require installation to use
