LiquiBase is a DBMS-independent library for tracking, managing, and applying database changes. It is built on a simple premise: all database changes (structure and data) are stored in an XML-based descriptive manner and checked into source control. While there have been many attempts to provide a similar tool, LiquiBase aims to provide a solution that supports merging of changes from multiple developers, works well with code branches, supports a database refactoring IDE/plugin, and more.
jf-unittest is a C++ unit test framework modeled after the way the Python unittest module is used in the Confix test suites. It was written out of frustration with the existing unittest frameworks. As such, it contains no bloat: no GUI with colorful progress bars, no dependencies on any other packages.
Perl::Critic is an extensible framework for creating and applying coding standards to Perl source code. Essentially, it is a static source code analysis engine. It is distributed with a number of Perl::Critic::Policy modules that attempt to enforce various coding guidelines. Most Policy modules are based on Damian Conway's book Perl Best Practices. However, Perl::Critic is not limited to PBP, and will even support Policies that contradict Conway. You can enable, disable, and customize those Polices through the Perl::Critic interface. You can also create new Policy modules that suit your own tastes.
