Subject: Manual Test::Unit and popen's require space

Hi, I'm trying to manully run unit test using Test::Unit because I need
to isolate certain requires from others in the
course of the tests. Certain files I'm testing can potentially cause
conflits with others, so I need to run them in isolation. But I still
want to tally the tests/assertions/errors, etc. So I'm wondering if I'm
doing this right. Specifically, is popen("-", "w+") giving me a whole
seperate "require space" to utilize?

Here's my code so far:

    def fork_test( testfile )
      result = nil
      IO.popen("-","w+") do |pipe|
        result = pipe.instance_eval do
          require 'test/unit'
          require 'test/unit/collector'
          require 'test/unit/collector/objectspace'
          require 'test/unit/ui/testrunnermediator'
          load( testfile )
          tests = Test::Unit::Collector::ObjectSpace.new.collect
          runner = Test::Unit::UI::TestRunnerMediator.new( tests )
          runner.run_suite
        end
      end
      p result
      result
    end

Thanks,
T.
