Litmus (Mozilla)

Litmus is a web-based, open source, test case management/QA tool, previously maintained by the Mozilla Corporation/Mozilla Foundation.
Mozilla used the tool to test its own products.
Requirements
Litmus depends on Apache web server and MySQL database software. It also requires the following Perl modules:
* Class::DBI
* Class::DBI::mysql
* Template
* Time::Piece
* Time::Piece::mysql
* Time::Seconds
* Date::Manip
* HTML::StripScripts
* HTML::StripScripts::Parser
* Text::Markdown
* XML::XPath
The use of the Apache module mod_perl is highly recommended as it highly improves the performance of the software, but not required.
