There's no tool, AFAIK, in RubyUnit for that. I guess there will be one
some day.

There's of course a Ruby way for the same thing.

# Simple test runner which runs all test in separate interpreters.
# Usage: ruby runit_all.rb [dir] [ruby] [unittest_re]
#
# Optional argument dir specifies directory where tests are collected.
#          Run like: runit_all.rb /home/foo/src/my_tests
#          Default value: .
# Optional argument ruby specifies the path and name to the ruby 
#          interpreter executed for each unit test file.
#          Default value: ruby
# Optional argument unittest_re specifies the regular expression used
#          to filter the unit test files out from the other files.
#          Default value: /UT.rb$/ according to 
# (C) 2001 Aleksi Niemela

dir = ARGV.shift || "."
ruby = ARGV.shift || "ruby"
unittest_re = ARGV.shift || Regexp.new(/\UT.rb$/)
unittests = Dir[dir+"/*"].find_all {|fname| fname =~ unittest_re }
unittests.each { |file| cmd = "#{ruby} #{file}"; %x{#{cmd}} }
