I don't know the reason why testing framework shouldn't
have setup_once and teardown_once and I want to know, too.

But I know the reason why RubyUnit has no these methods.
Because JUnit has no these methods.
(I referenced JUnit when I implemented RubyUnit.) 

And RubyUnit has RUNIT::Ext::TestSetup module like as JUnit.
This module provides the same functionality as setup_once and 
teardown_once.

require 'runit/testcase'
require 'runit/cui/testrunner'
require 'runit/ext/testsetup'

class TestFoo < RUNIT::TestCase
  def setup
    puts "\nTestFoo#setup"
  end
  def test_a
    puts "running TestFoo#test_a"
  end
  def test_b
    puts "running TestFoo#test_b"
  end
  def teardown
    puts "\nTestFoo#teardown"
  end
end

class OnceSetupTeardown
  include RUNIT::EXT::TestSetup
  def setup
    puts "\nOnceSetupTeardown#setup"
  end
  def teardown
    puts "\nOnceSetupTeardown#teardown"
  end
end

RUNIT::CUI::TestRunner.quiet_mode = true
RUNIT::CUI::TestRunner.run(OnceSetupTeardown.new(TestFoo.suite))


But I think TestSetup module is not convenient because
OnceSetupTeardown#setup(teardown) can not share (or access)
TestFoo instance variable(test fixture).

 Thank you.
