ruby-test-unit 2.5.5-1build1 (i386 binary) in ubuntu utopic

 Test::Unit is a testing framework originally bundled with Ruby 1.8.
 .
 This package provides an updated version of this framework, with many fixes and
 improvements, and support for Ruby 1.9, which bundles minitest, but not
 Test::Unit.
 .
 Note that this version of Test::Unit will override the one possibly shipped
 with the Ruby interpreter.
