GTestRunner is a graphical frontend for Perl unit tests, similar to JUnit. The package offers several improvements over the command line or Tk interface that ships with the Perl unit testing framework Test::Unit. The tree view visualizes the test suite hierarchy in an intuitive way. You can select arbitrary subtrees of of the test tree and run only these parts, and you can load and reload multiple test suites at once.
The package is fully internationalized and currently available in English, German and Bulgarian.
